DAILY MAINTENANCE
3-5Operation Manual
Avoid fire when
using isopropyl
alcohol to reduce
the risk of burning.
CAUTION
1. Moisten a cotton swab with isopropyl
alcohol.
2. Use the cotton swab to clean the thermal
head. Rub the swab back and forth across
the print head.
Although the cleaning frequency depends
on the operating conditions (quality of the
paper media used, dusty atmosphere, etc.),
you should clean the thermal head at least
once every 5,000 documents.
3.1.3 Cleaning the Thermal Head
Clean the thermal head when replenishing a bin with documents or when changing the
transfer ribbon. Use a cotton swab moistened with isopropyl alcohol. Do not use thinner or
benzene.
Note!
Be careful not to injure your hands when cleaning the thermal head.
Using thinner or benzene to clean the thermal head will damage the head and
may void your warranty.
A dirty thermal head lowers printing clarity.
The following explains how to clean the thermal head. Before cleaning the thermal head,
remove the transfer ribbon. (See the "Changing Transfer Ribbons" section)
