HP Designjet 4500 Printer series - Manual (Page 214)

Clean the exterior of the printer
Clean the outside of the printer and all other parts of the printer that you regularly touch as part of
normal operation (e.g. ink cartridge drawer handles) as required with a damp sponge or a soft cloth
and a mild household cleaner such as non-abrasive liquid soap.
WARNING! To avoid an electric shock, make sure that the printer is switched OFF and
unplugged before you clean it. Do not let water get inside the printer.
CAUTION Do not use abrasive cleaners on the printer.
Clean the input rollers
You should plan to clean your printer's input rollers on a regular basis, once a year or when you
notice a loss of roll switching performance.
1. Unload all paper from the printer.
2.
At the front panel, select the icon, then Paper handling options > Clean roller > Input
roller 1 or Input roller 2. This command will rotate the roller so that the whole circumference
can be cleaned.
NOTE If you are using the HP Designjet 4000 Printer series, and you find that these
commands are not available, please download the latest firmware revision (see Update
my printer's firmware). It will be available from Spring 2006.
3. Use a clean, absorbent lint-free cloth, slightly dampened with isopropyl alcohol, to wipe off any
dirt or paper particles from the input rollers.
NOTE Isopropyl alcohol is not provided in the Maintenance Kit.
4. When you have finished cleaning a roller, press the Select key on the front panel to stop the
rotation.
Clean the platen
You should plan to clean your printer's platen on a regular basis, every few months or when needed.
NOTE If you print on wide paper after using narrower paper for some time, you may find that
the left side of the platen has become dirty and will leave marks on the back of the paper if not
cleaned.
