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.
