HP 3100 - Manual (Page 59)

Align the print cartridges
The HP Fax prompts you to align cartridges every time you install or replace a print
cartridge. You can also align the print cartridges at any time from the control panel.
Aligning the print cartridges ensures high-quality output.
NOTE: If you remove and reinstall the same print cartridge, the HP Fax will not
prompt you to align the print cartridges. It remembers the alignment values for that
print cartridge, so you do not need to realign the print cartridges.
To align the print cartridges from the control panel when prompted
1. Make sure you have letter or A4 unused plain white paper loaded in the input tray,
and then press OK. The HP Fax prints a test page.
2. Load the test page print side down in the ADF, and press OK. Recycle or discard the
page after the alignment is completed.
NOTE: If you have colored paper loaded in the input tray when you align the print
cartridges, the alignment will fail. Load unused plain white paper into the input
tray, and then try the alignment again.
If the alignment fails again, you might have a defective sensor or print cartridge.

Clean the print cartridges
Use this feature when there is streaking, white lines through any of the lines of color or
when a color is muddy after installing a print cartridge for the first time.
NOTE: Ink from the cartridges is used in the printing process in a number of different
ways, including in the initialization process, which prepares the HP Fax and cartridges
for printing. In addition, some residual ink is left in the cartridge after it is used. For
more information see
