4.2 Driving units
When servicing gears or other driving units, be sure to turn off the power switch and unplug the power
cord. Drive them manually when required.
Do not do the print work removing the cover of the printer to confirm the operation
of driving part.
4.3 High-temperature units
When servicing high-temperature units (securing unit, etc.), be sure to turn them off to prevent burns,
injuries and other troubles. Remove the power plug and start service processes after they have cooled
Because high-temperature units are still hot after they complete an operation, wait
at least 40 minutes before starting maintenance service.
