To replace the print cartridges
1. Make sure the HP Fax is plugged in.
CAUTION: If the HP Fax is off when you open the print cartridge door to access
the print cartridges, it will not release the cartridges for changing. You might
damage the HP Fax if the print cartridges are not docked safely when you try to
remove them.
2. Open the print cartridge door.
The print carriage moves to the far right side of the HP Fax.
3. Wait until the print carriage is idle and silent, and then lightly press down on a print
cartridge to release it.
If you are replacing the tri-color print cartridge, remove the print cartridge from the
slot on the left.
If you are replacing the black print cartridge, remove the print cartridge from the slot
on the right.
4. Pull the print cartridge toward you out of its slot.
5. If you are removing the print cartridge because it is low or out of ink, recycle the print
cartridge. The HP Inkjet Supplies Recycling Program is available in many countries/
regions, and lets you recycle used print cartridges free of charge. For more
