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 qualified service personnel. Disconnect the power cord before servicing. Voltage is still present in the built-in power supply after the main switch is turned off.
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 qualified service personnel. Disconnect the power cord before servicing.

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:
Electronic components init
1.The front panel shows a white background and blue HP logo.
12 Chapter 1 Printer fundamentals |
ENWW |
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-off, the boot sequence automatically runs a file 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 finishes 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 132.
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.
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 off. 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.
