Manual

(This Includes The 3500c, 3530c,3570c Scanners)

Preparation

First Step; Unplug scanner from power supply and Computer.

Wait for at least 15 minutes (after disconnecting power)
before disassembling scanner and cleaning the glass.
This gives time for the scanner to cool.

Tools Needed;

Phillips Screw driver

Supplies Needed;

Glass Cleaner

Lint Free Cloth

Surroundings or Environment;

Disassemble scanner in a relatively clean dust free space.

Special Considerations;

Read through the entire process once before starting to clean the product, and

then decide if you want to do this or send it in to the Hewlett Packard service
center for cleaning.

Do not touch any other parts inside of the scanner. Some parts of the scanner are
very sensitive, especially to electrostatic discharge.

Disassembly

Step #1 Remove the Document Lid

Remove the document lid as shown. Open
the lid and lift straight up. Set the lid aside
for re-assembly later on.

Step #2 Cleaning Topside of Scanner

Clean the topside of the scanner prior to
disassembly to prevent contamination of
internal parts. Use cleaner sparingly. Do not
allow cleaner fluid to run. Clean the plastic
first and then use a separate lint free cloth to
clean glass.

NOTE: You are about to open the interior of your scanner to the dust of the outside
environment. Your scanner is very sensitive to any dust particles that get into the carriage
head, which can cause streaks in the scanned image. Minimize the time that the top cover
is off by having all the cleaning materials ready. Also be sure to disassemble your
scanner in a clean environment.
