Power
Always disconnect the power plug before doing any maintenance procedure. After
switching off the machine, power is still supplied to the main machine and other
devices. To prevent electrical shock, switch the machine off, wait for a few
seconds, then unplug the machine from the power source.
Before you do any checks or adjustments after turning the machine off, work
carefully to avoid injury. After removing covers or opening the machine to do
checks or adjustments, never touch electrical components or moving parts (gears,
timing belts, etc.).
After turning the machine on with any cover removed, keep your hands away from
electrical components and moving parts. Never touch the cover of the fusing unit,
gears, timing belts, etc.
Installation, Disassembly, and Adjustments
After installation, maintenance, or adjustment, always check the operation of the
machine to make sure that it is operating normally. This ensures that all shipping
materials, protective materials, wires and tags, metal brackets, etc., removed for
installation, have been removed and that no tools remain inside the machine. This
also ensures that all release interlock switches have been restored to normal
operation.
Never use your fingers to check moving parts causing spurious noise. Never use
your fingers to lubricate moving parts while the machine is operating.
Special Tools
Use only standard tools approved for machine maintenance.
For special adjustments, use only the special tools and lubricants described in the
service manual. Using tools incorrectly, or using tools that could damage parts,
could damage the machine or cause injuries.
