FAX-L350  Chapter 3: Maintenance and Service

 2. HOW TO CLEAN PARTS

2.1 Main Unit Outer Covers

Lightly wipe the unit’s outer causing with a clean, soft, lint-free cloth moistened with water or diluted

dishwashing detergent solution.

2.2 Separation Roller

Wipe with a soft, dry clean cloth.

2.3 Separation Guide

Wipe with a dry clean soft cloth.

2.4 White Sheet

Wipe with a soft, dry clean soft cloth.

2.5 Scanning Glass (Contact Sensor)

Wipe with a soft, dry clean cloth.

2.6 Paper Feed Guide

Wipe with a clean, soft, dry, lint-free cloth to remove any toner or paper debris.

Do not touch the transfer changing roller during cleaning.  Otherwise, the print quality may
deteriorate.

If Separation roller, Separation guide and Paper pickup roller are very dirty, wipe with a cloth
moistened with Isopropyl alcohol (IPA).  Do not use tissue paper.  Dust from the tissue paper

causes static electricity.

Precautions when using Isopropyl alcohol (IPA)

When cleaning with IPA, take care to prevent the IPA from splashing high-temperature
parts.  If IPA splashes high-temperature parts, leave for at least three minutes to allow the

IPA to evaporate.
