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.

Self
test
This procedure is a remnant of previous products and no longer provides a test of the device.

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.

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.
