Readership

The procedures described in this service manual are to be performed by HP Certied service personnel only.

Part numbers

Part numbers for printer service parts are located in Parts and diagrams on page 240.

Warning labels

Electric shock hazard
Hazardous voltage inside the printer (built-in power supply) could result in death or serious personal injury. See the installation instructions before connecting power. Ensure that the input voltage is within the printer's rated voltage range. Use only earthed mains outlets and the power cords supplied by HP with the printer. There are no operator-serviceable parts inside the printer. Refer servicing to qualied service personnel. Disconnect the power cord before servicing. Voltage is still present in the built-in power supply after the main switch is turned o.
Double pole/neutral fusing
Electric shock hazard. The built-in power supply incorporates a fuse on each conductor, therefore the printer could be energized even when one fuse has blown. There are no operator-replaceable fuses inside. Refer servicing to qualied service personnel. Disconnect the power cord before servicing.
ENWW Introduction 5

Theory of operation

Schematics

Electronics are based on 3 main components:
E-box - contains the power supply and all the PCAs (driving the printer), plus the Ethernet port.
Carriage PCA - drives the printhead.
Front Panel - user interface and USB port.
The following diagram describes the connections between components and electronic boards and the data line type for T920, T1500 and T2500.

Printer Initialization

There are 3 main blocks to be initialized before the printer can be operated:
ENWW Theory of operation 13
Electronic components init
1. The front panel shows a white background and blue HP logo.
2. The upper LED in the formatter is ON, indicating that the formatter has been initialized.
3. The middle LED in the formatter blinks, indicating that the HDD has been initialized.
NOTE: Steps 2&3 are the same when waking from Sleep Mode except the 3 LEDs are not on but; ON-
Blinking-OFF
OS & Firmware init
1. The OS is loaded into RAM. The Front Panel blinks for a second.
2. If boot up is after a bad power-o, the boot sequence automatically runs a le system check.
a. The Front Panel shows the FSCK, text.
b. First, FSCK runs on the root partition.
c. If FSCK is successful, the OS boots up from the root partition and runs FSCK on the data partition.
3. After FSCK, the OS nishes booting from the HDD.
4. The home button lights up to allow stopping the boot sequence, and entry to the diagnostics menu, see Diagnostics, Service Utilities and Calibrations on page 179.
Mechanical components init
1. The Front Panel shows a black background with a blue circle in the middle. The “Initializing” message
appears. A progress bar shows the percentage of subsystems that have been initialized.
2. The printer moves the carriage from side to side to validate its position within the scan axis. The printer
initializes the service station, moving the caps from bumper to bumper.
14 Chapter 1 Printer fundamentals ENWW
3. The pinches move down into position.
4. T2500 and T3500 only: The printer will initialize the Scanner and start checking it.
5. The carriage and service station move to the home position
6. The printer checks the status of supplies and the printhead, and then initializes the Ink Supply Stations.
7. Servicing routines are launched. The routines refresh the printhead depending on the time that the printer
has been o. The Front Panel shows “Preparing Print System”.
8. The paper path subsystems are initialized by exercising the ramps and rewinder, checking if there is media
present over the Media Sensor.
9. At the end of the process, the home screen appears in the Front Panel.

The following tables show the front panel menu layout.
