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.
The finish of prints may be stained or blurred if the
thermal print head of the master making unit, parts
such as the scanner glass and white sheet of the
optional auto document feeder, or other parts are
contaminated with dust, dirt, white-out, etc. We rec-
ommend that you perform maintenance periodically.
Do not perform any procedures (adjustment, repair,
etc.) that are not described in this guide. When you
want to adjust or repair, consult your dealer or
authorized service representative.
