maintain your hp psc
The HP PSC requires little maintenance. Sometimes you might want to clean the
glass and lid backing to remove surface dust and ensure that your copies and
scans remain clear. You might also want to replace, align, or clean your print
cartridges from time to time. This section provides instructions for keeping your
HP PSC in top working condition. Perform these simple maintenance procedures
as necessary.

clean the glass
Dirty glass from fingerprints, smudges, hair, and so on slows down performance
and affects the accuracy of features such as Fit to Page.
1 Turn off the HP PSC, unplug the power cord, and raise the lid.
2 Clean the glass with a soft cloth or sponge slightly moistened with a
nonabrasive glass cleaner.
Caution! Do not use abrasives, acetone, benzene, or carbon
tetrachloride on the glass; these can damage it. Do not place or
spray liquids directly on the glass. They might seep under it and
damage the HP PSC.
3 Dry the glass with a chamois or cellulose sponge to prevent spotting.
clean the lid backing
Minor debris can accumulate on the white document backing located
underneath the lid of the HP PSC. This can cause problems during scan or copy
tasks.
1 Turn off the HP PSC, unplug the power cord, and raise the lid.
2 Clean the white document backing with a soft cloth or sponge slightly
moistened with a mild soap and warm water.
3 Wash the backing gently to loosen debris; do not scrub the backing.
