4 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 3150
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.
