INTRODUCTION
Important!
Be sure to turn off the main power switch and disconnect the power plug before starting
to disassemble the machine; in addition, keep the following in mind for the work:
1. In printer mode, turning off the main power switch can result in the loss of data being
processed. Check to make sure that the Execution/Memory lamp on the control panel
is off before operating the main power switch.
2. Do not turn off the main power switch while downloading is taking place. Otherwise,
the machine may become disabled.
3. The cassette heater and the drum heater remain powered as long as the environment
switch and the heater switch are on (even when the main power switch is off).
4. Not all power is removed when the front cover is opened if the main power switch is
on, requiring care.
