The front panel has a large central area to display dynamic information and icons. On the left and right sides you can see up to six fixed icons at different times. Normally they are not all displayed at the same time. To the right of the front panel is the Power key, with which you can turn the printer on or off. The key is illuminated when the printer is on. It flashes when the printer is in transition between on and off.
If a network cable is connected, is displayed instead. NOTE: It is not possible to use wireless and wired network connections simultaneously. NOTE: The active paper source is indicated by a slightly larger icon, with a white tick in a green circle:. If the printer is left idle for some time, it goes into sleep mode and switches off the front-panel display. You can set a time between 5 and minutes. The printer wakes from sleep mode and switches on the front-panel display whenever there is some external interaction with it.
The following table shows an overview of the two types of support menu available, for more details see Entering the support menus on page NOTE: The icons mentioned in this table will not be visible in the front panel: you must press the front panel in the places where they normally appear, as shown in the front panel illustration at the start of this section. In this case, press the Power button and hold it down for.
Electronics initialization. The front panel moves from flashing white light to turning dark. The printer reads the firmware. To diagnose what is happening, go to the front panel blank troubleshooting. Subsequently, you can enter the Support menu to troubleshoot if necessary. The HP logo appears with a static bar. Bundle board and ASICs are initialized. A check that the Scan Axis and Paper Axis are unobstructed by scraps of paper or other items. Paper and print system initialization. NOTE: Initialization lasts around 45 s if there was a clean power-off using the front panel Power button.
If there was a dirty power-off, the printer will require more time to inititialize to ensure that the printhead is in a good state. These parts cover the printing mechanism and act as protection from potential knocks or dust. They also prevent the customer from coming into contact with unsafe parts during the operation of the printer. Finally, the covers complement the style and aesthetics of the printer.
The T and T printers have covers of different colors, and a different configuration of the roll cover, as seen in the following table:. Other than the cosmetic aspects of the covers, there are several sensors related to the subsystem covers. The sensors are designed to detect the status of the cover, open or closed. Opening the Ink Cartridge Cover starts ink cartridge replacement automatically.
The sensor is hosted in the printer chassis. See Central Cover on page To avoid paper jams while printing on roll paper, the tray should be closed. In order to proceed with the removal and installation of the covers its important to bear in mind their cosmetic aspects, some surfaces of the covers have a glossy finish, which requires maximum attention as they are very delicate and susceptible to scratches and finger marks.
It is recommended that you use gloves for any service operation involving the covers. Due to the layout of the covers, it is important to bear in mind that some parts require removal before you can remove a specific cover. See Diagnostics menu on page Other than the sensor boards, there are no electronics related to this subsystem. The service station is responsible for printhead maintenance. It takes action to clean ink residues and service ink nozzles, and prevents ink from drying in critical zones by capping the printhead once printing has finished.
The Primer system provides the necessary air pressure to the printhead to perform initialization. This system also provides pressure to the necessary printhead service operations by boosting air which pushes ink out through the printhead nozzles, cleaning residues of dried ink and other particles. Any leakage in the primer system will generate poor or no priming, this will affect nozzle heath or even cause the printhead startup to fail. Bear in mind that the system is not just for the Prime Pump and tubes, the prime pressure is transmitted via the off-axis coupling to the Carriage and from there to the printhead assembly and from there to the cartridges.
NOTE: There is no pressure sensor in the system. The Prime Pump operates at a certain time to reach a specific pressure level, the system is depressurized by releasing the pinching of the release tube in the Service Station by moving the service station. NOTE: It is important to ensure the Carriage reaches the maximum left position; if not, the off-axis coupling will not connect the Prime Pump with the Carriage.
Also, the coupling is made of a rubbery material, degradation of the material will affect Primer performance due to air leaks. The control driver of the Prime Pump is located on the remote controller board located on the right-hand side of the printer. There is no encoder for the Prime Pump. This pump is managed only by a DC motor activated for a certain period of time to create the required priming pressure.
Wiping: A physical action to pass the rubber wipers through the. Capping: Parking the printhead to maintain nozzle heath during. Priming: Squirts ink through the nozzles to clean and unblock.
The service station is offered as a complete service part for full replacement. The failures from this subsystem are usually related to the mobile parts: motor or encoder failures that prevent the shuttle from reaching the positions for capping or uncapping. With the life primer system, tube pinching can present an issue although it is designed to function for the life of the printer.
When the Service Station is replaced, it is mandatory to reset the Preventive Maintenance Kit for the Service Station, this will trigger a simple calibration that is done with the Service Station on the next printer startup.
The calibration measures the length of the Service Station shuttle front bump to shuttle rear bump , which ensures a correct capping position. All the controlled movements for the Service Station are done from the remote-controlled board located on the right-hand side of the printer. Issues with the Service Station can also be related to this control board. This comprises all the elements of the printer in contact with the paper, designed to hold, move, and manage it in a controlled manner in order to print.
Paper can be loaded using a roll, which is mounted on the rear spindle, or single sheets loaded from the Multi-Sheet Tray, or single sheets loaded singly. The paper passes from its source Roll, Single Tray, or Multi-Sheet Tray until it touches the Out-Of-Paper Sensor, when the printer detects the presence of the paper and proceeds to load it. To perform the paper feed, the printer catches the paper in between the Drive Roller and the Pinch Rollers Pinch Rollers are spring-loaded pushing the paper down on top of the Drive Roller , then the paper is pushed forwards on top of the Print Platen in the print zone, which is where the printing operation is performed.
The paper advance is provided by a motor that moves the Drive Roller. The exact position of the Drive Roller and hence the paper is controlled by an Encoder Disk located on the roller axis. The printed paper then passes between the Output Shaft and the Starwheels which keep the paper tension as flat as possible for printing to exit on the Output Platen, where it is held in case of cut sheet or is cut to fall on the output basket in the case of roll paper.
The Output Shaft is designed to over-advance the Drive Roller movement slightly, and hence create the necessary paper tension to keep the paper as flat as possible. The Starwheels are spring-loaded and are designed to create force on top of the paper, this is done so as to leave the paper unmarked and at the same time allow the Output Shaft force to be appropriately transmitted.
In the Roll configuration, the rewinder module generates back force while printing to facilitate paper control. This sensor is located at the beginning of the Print Platen; it detects paper insertion for roll load and single-sheet load. In the paper-path driving system, the only electrically active element is the Drive Roller. The Drive Roller is impelled by the drive roller motor and it contains an Encoder Disk on the axis to determine its position.
The Encoder Disk is read by two sensors. If this search fails which means that the index sensor is faulty , the printer will give a system error and will be unable to initialize. It contains the rewinder, which rewinds the paper for paper ejection, and provides an opposite tension to the paper advance for better paper control.
There is a V-shaped spring to load and fix the spindle in position. In the T, the right support also contains the dampers for the roll cover opening movement control the internal dampers perform a braking action preventing sudden movement during the opening operation. The T and T have two different assemblies from the factory, nevertheless both can be replaced by the damper option of T identical from the external point of view , and there is only one service part available.
It consists of a central bar and two hubs; the right hub is fixed to determine the right-side loading position of the paper, and the moveable left hub adjusts to the width of the paper.
The system ensures that the printed paper follows a controlled path and acquires a certain shape in order to be delivered properly to the user. It also has a cosmetic function. The system includes a set of three telescopic trays, which are extended to collect the cut-sheet paper printed from the Multi-Sheet Tray.
There are two roll-paper control tabs that are deployed automatically when the telescopic trays of the Output Tray are in the closed position. This is a purely mechanical action as the tabs are pushed up by the output trays when closed. The purpose of those tabs is to control the shape of the roll paper when coming out of the paper path. The only electronic component related to the Output Platen is the Output Tray Sensor located underneath the output trays.
The sensor is activated when the three output trays are fully closed. The sensor cable is routed via the front of the machine and is directly connected to the main PCA. It comprises 1 a cutter module that cuts the paper with two rotary blades, 2 a Cutter Bridge attached to the Carriage that catches and releases the Cutter to perform the cutting operation and then to leave it in capping position, 3 a Cutter Guide that holds the movement of the Cutter along the printer width.
In order to operate the Cutter, it needs to be in the parked position. If not, the Cutter will not be engaged by the Cutter Bridge and the printer will not perform the cutting action.
Whenever the printer initializes, it performs a parking movement with the Carriage to ensure that the Cutter is left in the appropriate position. The printer does not have any feedback about the cutter engagement action.
Hence, if for any reason the engagement is not performed correctly, the printer will continue operating as if the engagement has occurred. Pre-activation phase: The Cutter Engagement Feature of the Bridge gets into the funnel of the Cutter Module grooving the Cutter to ensure the correct position for activation.
Hook catching: The cutter bridge continues moving to the left pushing down the cutter hook in orange , after the left side of the cutter bridge passes the Carriage stops and the cutter hook returns to its position due to its spring motion.
Cutter action: The left feature of the cutter bridge pushes the cutter to the left, performing the cutting operation. Disengagement: Hook Bridge changes direction moving now from right to the left, so that Cutter Hook slides out of the Cutter Catch Feature. Move-away action: the Cutter Hook deactivates from the bridge by passing in front of it. The accessory tray holds and loads the cut-sheet paper for the printer.
The accessory tray itself is a completely mechanical system with no electronics or motors. All the motion drives for both picking and paper drive are or created or transmitted by the Right Gear module located on the right-hand side of the printer, behind the Service Station. The Right Gear module has two main functions. It contains the motor encoder and gear drive system for the picking mechanism, and it contains the gear train system to transmit the movement from the drive roller to the accessory tray.
The paper drive from the Multi-Sheet Tray into the platen area until the cut sheet reaches the drive roller area. The intermediate shaft in the Multi-Sheet Tray is driven by the drive roller through a gear train inside the Right Gear module. The intermediate shaft meshes with the Multi-Sheet Tray gear interface red gear in the picture at the end of the train. A swing arm engages the gear train when the Drive Roller is driven backwards as shown in the picture , driving the intermediate shaft forwards.
When the Drive Roller is driven forwards, the swing arm disengages from the gear train and the intermediate shaft is not driven. This action is to prevent reverse paper movement to be transmitted to the Multi-Sheet Tray.
Picking functionality drive system. The Multi-Sheet Tray pick drive assembly is mounted in the right side gear module. The assembly contains a DC motor and pinion, belt, cluster pulley, and gear.
An encoder not shown, but it is located in front of the white gear shown in the picture is read by the encoder sensor in red in the picture to servo-control the pick drive. The two gears from the Right Gear module interface with the Multi-Sheet Tray by location once the MultiSheet Tray is locked in position; both gears can be considered fully engaged. The function of the Multi-Sheet Tray is to pick and feed the cut-sheet paper until the paper is grabbed by the drive roller drive roller and pinch system.
The actions performed for those operations are 1 sheet pick and 2 sheet input. This movement is transmitted through a lateral gear chain in the Multi-Sheet Tray towards the swing arm, which is pushed towards the paper, and the picking mechanism located at the bottom of the Multi-Sheet Tray, which separates the top sheet from the stack of pages.
Once the paper is in the intermediate shaft area, the drive roller is rotated, impelling the intermediate shaft through the right gear module, pushing the sheet towards the inside of the printer, so that it will be grabbed by the drive roller and main printer pinch system, proceeding with the standard paper drive motion as with roll paper. NOTE: The printer considers the load successful if, after the picking and sheet input procedures, the sheet is detected by the printer's Paper Sensor.
Hence, a correct function of the Paper Sensor is required also for the accessory tray loading action. NOTE: It is possible to reproduce the picking and loading motions by extracting the Multi-Sheet Tray and rotating the gears with the hand, to validate module performance and troubleshoot any possible mechanical issues. Both the encoder and motor-drive system are managed by the Bundle PCA located on the right-hand side of the printer.
This system moves the Carriage from left to right and right to left of the printer on top of the paper in a controlled manner to perform printing, cutting, paper detection, and any other Carriage movements for servicing and final capping process.
The system comprises the Carriage sliding on the scan axis rod, on which rotates and whose position is determined by a cam mounted on the Carriage, which slides touching the bottom surface of the anti-rotation rail. There are two trailing cables mounted one on top of the other, which connect the Carriage with the main electronics control board.
A scan-axis encoder strip is needed for the Carriage to determine its position, and a Carriage Motor which impels the Carriage via a belt.
The trailing cable is held in position by a plastic holder, which clips onto the scan axis structure. A springloaded loop ensures follow-up action of the cables with the Carriage movement. Two plastic cable sliders are also placed to ensure minimum contact of the trailing cables with the scan axis structure.
The plastic sliders are greased to prevent ink spray aerosol deposits from accumulating on them, generating a sticky surface which could retain the cables and then be damaged by Carriage movement. The Encoder Strip Sensor is located inside the Carriage, once the Carriage is assembled the Encoder Strip crosses the Carriage, passing by the detection area of the sensor inside the Carriage. The main function of the Carriage is to hold the printhead in position, to enable cartridge insertion, and to move the printhead in a controlled manner in order to print.
The Carriage holds all the necessary interface electronics for the main board to interact with the printhead via the trailing cables. A set of spring-loaded connectors are the main interface Carriage-printhead. This is particularly important when replacing the printhead, as the removal of the old printhead extraction with a rotary movement can cause the nozzle plate to touch those contacts and create contamination that could cause problems with the new printhead.
However, manual cleaning of the contacts is not recommended. Transmits the pressure from the Prime Pump via off-axis coupling to each of the four cartridges. The cutter bridge impels the Cutter for cutter operations see additional information in the cutter section. Holds the Carriage Line Sensor.
The Carriage Line Sensor also known as the ZIM Sensor is located on the right of the printer and is used to detect the edges of the paper to determine the paper dimensions and start position. This sensor is also the tool used to detect the position of printed lines to perform calibrations Paper Advance calibration and printhead alignment. The Line Sensor is a reflective tool that generates a beam of LED light, whose reflection is detected by a luminance sensor. The signal from this sensor is used to determine the position of lines or paper edge according to the position of the Carriage.
If this cover becomes dirty, the signal to detect edges or lines will be affected, which could cause intermittent issues during the paper load. It can also detect printed lines from short signals when the sensor crosses the lines:. In manufacturing, the anti-rotation rail area in which the PRS cam slides is adjusted to calibrate the nozzle plate position of the printhead, at around 1.
This calibration is not service-adjustable and should remain constant throughout the printer's life. As there are different paper thicknesses, the printer is able to rotate this sliding cam automatically to three different positions, changing the PRS distance to accommodate it to the appropriate printing distance.
This rotation is performed by taking the Carriage to a feature on the left-hand side of the scan axis, different side movements of the Carriage at different speeds allow this feature to grab and rotate the cam accordingly. The Cam has three different areas for three different PRS adjustments.
Back part of the Carriage with auto-PPS cam, after being activated in position 1. The encoder strip tension is also fixed by a tensioning spring. However, there is a mechanism to hold it in position after the spring places the strip at one specific tension. This is to prevent the spring from continually applying force over the encoder strip; which, over time and temperature changes, could make it creep.
NOTE: When assembling the encoder strip, ensure that it is placed in the right orientation using the smiling symbol located on the sides of the encoder strip.
NOTE: Due to the proximity of the encoder strip to the greased sliding rod, it is easy to dirty the strip with grease when performing any repair operation in the area. Please clean any grease from the encoder strip if necessary. A dry cloth can be used for this purpose, to prevent any deformation or strain on the encoder strip while performing the cleaning. The printer contains several electronics boards and electrical and electronic components in different locations.
Located in the front panel, it is used to power the printer on and off. The standard wiring used in the printer is Flat Flexible Cables FFCs , to interconnect all boards including sensors and encoders and distributed cables for power signals to the motors.
NOTE: It is important to bear in mind that FFCs are relatively delicate, so please ensure cable connectors are not touched or dirtied during manipulation for assembly and disassembly operations.
NOTE: Ensure that you are properly grounded for any electronics or wiring manipulation. The Main PCA is located on the left-hand side of the printer.
The internal clock is used to remember the actual date, used for cartridge life counting and warranty accounting. It is a customized device designed to interact with the main electronics, and all the data are appropriately encrypted. The Bundle Board is located on the right-hand side of the printer, this board includes a driver ASIC to control and manage the motor, encoder, and sensors located on the right-hand side of the printer.
The following diagram describes the connections between components and electronic boards, the voltage, and the type of data line. If all is in order paper loaded, all ink components installed, and no file errors , there are still reasons why a file you have sent from your computer may not start printing when expected:. You may have an electrical power problem.
If there is no activity at all from the printer, and the front panel does not respond, check that the power cord is connected correctly and that there is power available at the socket. You may be experiencing unusual electromagnetic phenomena, such as strong electromagnetic fields or severe electrical disturbances, which can cause the printer to behave strangely or even stop working. In this case, turn off the printer using the power key on the front panel and unplug the power cord, wait until the electromagnetic environment has returned to normal, then turn it on again.
Check the Touch Control Panel display message. If the problem remains, try a new printhead. As long as the product is kept turned on, an autom atic cleaning is performed periodically. This ensures there is fresh ink in the nozzles and prevents nozzle clogs, which ensures color accuracy.

To clean the printheads, press the Menu key to return to the main menu and select the Image Quality Maintenance menu icon, then Clean printheads. If you have gone through the Image Quality Diagnostic print process, you knowwhich colors are failing. Select tothe pair of printheadswhich contain thefailing colors.
If you are not sure which colors to clean, you can also select to clean all printheads. Cleaning all printheads takes about nine minutes. Cleaning a single pair of printheads takes about six minutes. Cleaning all printheads uses more ink than cleaning a single pair. If you have cleaned the printheads using the Clean printheads procedure from the Touch Control Panel and are still experiencing image quality problems, you can try cleaning the printhead nozzles manually using the following procedure.
NOTE: This is a delicate process and may damage the printhead. Do not touch the electrical connections on the backside of the printhead. You must remove the printhead see Changing a Printhead on page 20 and using a cotton swab and a little de-ionized, distilled water, or Carriage Interconnect Wiper clean the bottom of the printhead until the residue is removed.
All theinstructionsneeded to use the Flex Contacts Cleaning Tool will be packaged with the kit. Whenever you replace the Printhead, check the empty slots to see if they need cleaning. In extreme circumstances, when a Printhead is inserted, it is possible that the product will not recognize it due to the build-up of ink on the electrical connection between the Printhead and the Carriage Assembly. Included with the product is a Flex Contacts Cleaning Tool.
This tool is provided in a separate package. It also contains replacement sponges and an instruction sheet. This tool should be used for cleaning the electrical interconnects of both the Carriage Assembly and the Printhead.
NOTE: Do not touch, wipe or attempt to clean the printhead nozzles. This can damage the printhead and reduce print quality. Follow the advice given in the appropriate section below.
