HP Fax 1200 Series
The print cartridges have microscopic nozzles that can clog when exposed to the air for
more than a few minutes. The unit is designed to prevent nozzles from drying out when
it is idle and when it is turned off using the On button located on the front panel.
A print cartridge that is not used for long periods of time can also clog, resulting in a
noticeable decrease in print quality. To unclog the nozzles, clean the print cartridges. For
more information, see "Clean the print cartridges."
Follow these steps to replace the cartridge.
1 Turn on the unit, and open the top cover.
The carriage moves to the center of the unit.
After the carriage stops moving, flip up the print-cartridge latch on the right, grasp
2
the top of the old print cartridge (the thinner one), and pull it up and out of its slot.
3 Remove the new black print cartridge (the thinner one) from its packaging and,
being careful to touch only the black plastic, gently remove both the green pull tab
and blue tape covering the nozzles.
