Service mode functions
Cold reset

A cold reset unlocks menus that have been previously locked and sets all control panel menu items (including EIO settings) back to the factory defaults. However, it does not clear the values in the SERVICE menu
1. Turn the device off.
2. Turn the device on. When the memory count begins, press and hold the button. Continue holding down the TICK button until all three device control-panel lights flash once and then remain on. This might take up to 10 seconds.
3. After the message SELECT LANGUAGE appears on the display, press the UP button or the DOWN button until COLD RESET is highlighted.
4. Press TICK . The device performs a cold reset and then continues its power-on sequence.
5. Check all I/O settings and reset any customer-set device configuration values.
NVRAM initialization
CAUTION: Initializing the NVRAM resets the serial number, the event log, the page counts, and the EIO card (initializing the NVRAM resets SERVICE menu values to factory defaults). Use the service menu to restore the serial number and page counts. Also reconfigure any computers that print to this device so that the computers can recognize the device. Initialize the NVRAM only when absolutely necessary. In most situations, use a cold reset rather than a NVRAM initialization to reset device settings.
1. Remove any installed accessories.
2. Turn the device off.
3. Turn the device on. When the memory count begins, press and hold the DOWN button. Continue holding down the DOWN button until all three device control-panel lights flash once and then remain on. This might take up to 10 seconds.
4. Press the UP button.
5. Press the Menu button. The display should show SKIP DISK LOAD.
6. Press the UP button until NVRAM INIT is highlighted.
7. Press TICK . The device initializes NVRAM and then continues the power-on sequence.
Hard-disk initialization
CAUTION: A hard-disk initialization erases and reformats the device hard disk. Perform a harddisk initialization only if an error code on the control panel indicates an EIO disk error. Always try
initializing the hard disk before replacing it.
1. Turn the device off.
2. Turn the device on. When the memory count begins, press and hold the Menu button. Continue holding down the Menu button until all three device control-panel lights flash once and then remain on. This might take up to 10 seconds.
3. Press the RETURN button. The display should show INITIALIZE DISK.
4. Press TICK . The device initializes the hard disk and continues the power-on sequence.
Skip disk-load
When the power is turned on the device begins the power-on sequence. By performing a power-on bypass, you can cause the device to resume the power-on sequence but not to recognize any installed EIO hard disk. This can be helpful in isolating EIO hard-disk errors.
1. Turn the device off.
2. Turn the device on. When the memory count begins, press and hold the DOWN button. Continue holding down the DOWN button until all three device control-panel lights flash once and then remain on. This might take up to 10 seconds.
3. Press the UP button, and then press the Menu button.
4. Press the UP button or the DOWN button until SKIP DISK LOAD is highlighted.
5. Press TICK . The device continues the power-on sequence but ignores an installed EIO hard disk.
Self test
This procedure is a remnant of previous products and no longer provides a test of the device.
Service menu (service PIN codes)
Authorized HP service technicians can use this menu to gain access to device settings that are reserved for service personnel. The SERVICE menu is protected by use of a personal identification number (PIN). When you select SERVICE from the list of menus, you are prompted to type an eight-digit PIN code.
NOTE: The device automatically exits the SERVICE menu after about one minute if no menu items are selected or changed.
Use the PIN code 10300506 for the HP LaserJet P3005 Series printer.
1. Press Menu. Use the UP button or the DOWN button to scroll to SERVICE, and then press TICK.
2. Press the UP button or the DOWN button until the first digit of the PIN code appears. Press TICK to save that digit. Repeat this selection procedure until you have typed the entire eight-digit PIN code. You can use the RETURN  button to return to a PIN digit. When the last digit is saved, the SERVICE submenu appears on the control-panel display.
3. Use the UP button or the DOWN button to scroll to the menu item that you want, and then press TICK.

# CLEAR EVENT LOG. Select this item to clear (reset to zero) the internal event log.
# ENGINE CYCLES. Select this item to set the total number of pages that have been printed to-date. Typically this is required only when a new formatter is installed.
# REFURBISH CYCLE COUNT. Select this item to reset the device page count after the device engine has been refurbished.
# SERIAL NUMBER. Select this item to update the serial number if you replace the formatter.
#  SERVICE ID. Select this item to specify the date when the device was first used, rather than the date when a replacement formatter is installed.
#  COLD RESET PAPER. Select this item to reset the default paper size when you replace the formatter or restore factory settings. When you replace a formatter or restore factory settings in a country/region that uses A4 as the standard paper size, use this item to reset the default paper size to A4. Letter and A4 are the only cold-reset values available.
Engine-test page
To verify that the device engine is functioning, print an engine-test page.
1. Remove the right-side cover.
2. Press the engine-test-page button (callout 1)

The test page should have a series of horizontal lines. The test page prints from the last tray that the device used to print, unless the device has been turned off and then turned on again since the most recent print job. If the device has been turned off and then on again since the most recent print job, then the page will print from tray 2. The device continuously prints test pages as long as the test-page switch is depressed. The device will not print a test page if it is in Sleep mode.
