PaperJet 55 user guide – Edition 3 – 10.10.01
Cleaning your PaperJet 55
First disconnect it from the mains power supply and
the telephone line.
Clean with a cloth dampened with diluted
washing-up liquid. Never use household polish as
this may damage your fax machine. Never use a dry
cloth as this may cause static shock.
Changing the printhead/cartridge
Your PaperJet 55 is supplied with a starter print
cartridge and it is not possible to change the ink
cartridge independently of the print head.
Replacements have ink cartridges which can be
replaced independently of the printhead. You can use
the same printhead with up to 6 cartridges. You should
then change both the cartridge and printhead.
Changing the printhead/cartridge assembly
1 Open the printer compartment cover.
2 Pull the green levers towards the front of the
machine to release the printhead assembly.
3 Lift out the assembly.
4 Remove the new printhead assembly from its
packaging. Holding it by the finger grip, peel the
protective film from the print nozzles.
5 Avoid touching the nozzles and metal electrical
contacts.
NOTE
For details on changing between black and colour
cartridges, see the separate PaperJet 55/65 PC
Printing Guide.
