Cleaning hints

■

Power can remain

while cleaning.

■

Use isopropyl alcohol that is at least 90% pure (99% yields the best
results).

■

Cleaning Kit (016-1400-00) includes the following items:

■

Cleaning tool

■

Foam cleaning swabs

■

Lint-free cleaning cloth

■

Empty bottle for isopropyl alcohol

You can separately order a pack of 10 pre-soaked alcohol cloths (006-7824-00)

Quick cleaning

As a general rule, you will get the best results from your printer if you perform
these quick cleaning procedures once a week or, as indicated in these
instructions, according to how much media you have used.

Feed rollers and paper guides

Clean the drum, feed rollers and paper guides after you have used
approximately 80 large-size prints such as ANSI E, Arch E, ISO A0 or JIS B1.

Open the top cover.

Moisten a lint-free cloth with 90% pure isopropyl alcohol (or use a
pre-soaked alcohol cloth).
