EN Cleaning the document scanner path 59
4 Inspect each of the six rollers in the
document scanner area for dirt or
debris. Using a lint-free cloth
dampened with a small amount of
isopropyl alcohol, wipe any dirty
rollers using a side-to-side motion.
CAUTION
Do not spray alcohol or any other liquid
directly into the HP LaserJet 3100/3150
product. Doing so can damage the
product.
CAUTION
As much as possible, avoid touching the
white sheet and the glass surface 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 dampened
with a small amount of alcohol.
6 Close the document release door
after allowing alcohol to dry.
Note
If, after cleaning the document scanner
path, you still notice that copies, items
scanned to the computer, or faxes you
send have black or white lines running
through them, see Chapter 6,
“Troubleshooting,” for information about
recalibrating the document scanner and
interpreting the calibration graph.
