Cleaning the scanner path
You may need to clean parts of the
scanner if the ink on items you are
scanning can be smudged with your
hand or they have excessive amounts of
dust or dirt on them. You may also need
to clean these parts if there are smudges
or other marks on documents or scans of
documents.
WARNING!
Before cleaning the HP LaserJet 3100
product, disconnect it from the power
source.
1
Open the document release door.
2
If the long, white strip on the inside
of the document release door is
dirty, clean it with a dry cotton
swab. If there is still something on
the strip, dab a swab in a small
amount of isopropyl alcohol and
gently clean the strip.
WARNING!
Alcohol is flammable. Keep it away from
open flame. Allow alcohol to dry
completely before closing the printer and
plugging in the power cord.
CAUTION
If you must use alcohol, only use a very
small amount. Exposing internal parts to
dripping alcohol can damage them.
3
If the long strip of glass opposite the
long, white strip is dirty, clean it with
a dry cotton swab. If there is still
something on the glass strip, dab a
swab in a small amount of isopropyl
alcohol and gently clean the glass.

Inspect each of the six rollers in the
scanner area for dirt or debris.
Clean any dirty rollers with a lint-
free cloth (such as lens tissues)
dampened with a small amount of
isopropyl alcohol.
CAUTION
Do not spray alcohol or any other liquid
directly into the HP LaserJet 3100
product. Doing so can damage the
product.
CAUTION
As much as possible, avoid touching the
white strip and glass strip with alcohol.
5
Near the top, inside edge of the
document release door, inspect the
three pressure feet and pad for dirt
or debris. If they are dirty, clean
them with a lint-free cloth sprayed
with a small amount of alcohol.
6
Using a dry, lint-free cloth, wipe
rollers, pads, and feet in a side-to-
side motion to remove loosened
dirt.
7
After alcohol inside the scanner
area has dried completely, close
the document release door.
