4.2 Drive units
When servicing gears or other drive units, be sure to turn them OFF and disconnect the
power plug from the receptacle. Whenever possible, drive them manually.
Never touch the gears or other moving parts while the printer is running.
4.3 High-temperature units
When servicing high-temperature units (removal, replacement, adjustment, etc.), be sure to
turn them OFF to prevent burns, injuries and an electrical hazard. Remove the power plug
from the receptacle and allow the unit to cool down before servicing.
Fusing units retain their heat after the power is removed. Wait at least 30 minutes
after removing power before servicing.
