Cleaning the document scanner path
Clean parts of the document scanner if
the ink on items you are scanning can be
smudged with your hand, or if the parts
have excessive amounts of dust or dirt
on them. Also clean these parts if there
are smudges, lines, or other marks on
original documents, copies, or scans of
documents.
WARNING!
Before cleaning the HP LaserJet 3100/
3150 product, disconnect it from the
power source.
1 Open the document release door.
2 If the white sheet is dirty, clean it
with a dry cotton swab. If there is still
something on the white sheet, dab a
swab in a small amount of isopropyl
alcohol and gently clean the white
sheet.
CAUTION
When you use alcohol, only use a very
small amount. Exposing internal parts to
dripping alcohol can damage them.
3 If the glass surface of the contact
image sensor is dirty, clean it with a
dry cotton swab. If there is still
something on the glass, dab a swab
in a small amount of isopropyl
alcohol and gently clean the glass.
