B. Perform Printer Self-Test Page:
7000 Printer Series:
1. Press and hold the OK button, and then press the Left Arrow button once.
2. Release the buttons. The internal test page prints.
8000 Printer Series:
1. Press CANCEL and SAVE simultaneously (SAVE is the left-most button before POWER on/off.)
2. Using left/right arrow keys, navigate to ‘pen electrical test’.
3. Select Enter to print test - evaluate nozzle test pattern.
-- If the printer prints the self test page then this demonstrates the printer is generally functional and
that the problem is likely with one of the ink cartridges. Please note this is a ‘forced’ service test…the
printer will attempt to print the test page whether the cartridges are good or bad. If the Self-Test
page can be successfully printed but regular/normal printing cannot, then one of the ink cartridges is
likely internally damaged. Remove and replace suspect cartridge to confirm.
C. Perform Cartridge Diagnostics tests using either C.1 or C.2 procedure below (varies by printer model):
C.1. Tap 41/43 Diagnostics Test:
1. To enter the Manufacturing Tests menu, press the 3 small, round buttons on the front panel
simultaneously for >5secs : ‘OK’, ‘CANCEL’, & ‘SELECT PHOTOS’ (or ‘Print Photos’)
2. Using left/right arrow keys, navigate to Special Reports (or System Menu). Select Enter.
3. Navigate to 'print-mech button tap' menu.
4. Select Ok (‘code = 0’ will be displayed); click and hold Right Arrow until ‘code = 41' (or attempt ‘code = 43’
if nothing prints using ‘41’) is displayed.
5. Select Ok. Within one minute the Tap 41 (or 43) diagnostic test pattern should be initiated and print.
Refer to video to help evaluate test pattern. Refer to 2nd video for guidance on how to read the
diagnostic test pattern: http://inkjet411.com/?page_id=1741
NOTE 1: A good HP 93/95/97/99 color ca rtridge should display 600 good nozzles, while a good HP 92/94/96/98 black
ink cartridge s hould show 672 good nozzles. If the results yield anything different then the ink cartridge is likely
damaged and will need to be replaced. For reference only, refer to the following HP Deskjet video which shows how
to read the HP 93-97 i nk cartridge diagnostic test print: http://inkjet411.com/?page_id=1741 (refer to 2
