such as the scanner glass and white sheet of the
document feeder, or other parts are contaminated

Thermal print head

The thermal print head is a component that produces
heat during master making and forms minute holes on
the master. Clean it whenever the master roll is
replaced.
Open the master making unit cover, and then gently
wipe the thermal print head in the back of the unit sev-
eral times with a soft cloth, etc.
Caution

touch it directly with your fingers.

icate. Avoid creating excessive impacts

static electricity. Be sure to remove the
static electricity charge that is accumu-
lated in your body before cleaning.
