1.3 Cautions for Service Operations
1)
When servicing the printer, be sure to remove the power cord from the power outlet except when
absolutely necessary.
Unless specifically indicated, whenever the printer power is ON, never touch any of
the electrical components.
The power switch/inlet of the LVPS has voltage present even while the power
supply is cut off. Never touch any of the electrical components.
2)
When it is necessary to check a component(s) with covers removed and with the interlock and
safety and power switches ON, remove the connector (P/J140) on the ROS ASSY.
When checking some parts with covers removed and with the interlock and safety
and power switches ON, laser beams may be emitted from the ROS ASSY. Since it
is dangerous, be sure to remove the connector (P/J140) while performing service.
3)
When it is necessary to check a component(s) with the left cover removed and power ON, be sure
to remove the HVPS connector (P/J31) while servicing the printer.
When checking some parts with the left cover removed and power ON, high voltage
may be applied by the HVPS. Be sure to remove the connector (P/J31) on the HVPS.
When connecting the connector (P/J31) on the HVPS according to the instructions
of the FIP, never touch the HVPS or any of its parts.
4)
When using Diagnostic tools or a meter to measure high voltage, be sure to keep the components
covered unless specified.
When using Diagnostic Tool or a meter to measure high voltage, never touch parts
of high voltage.

5)
When operating a drive unit using the Diagnostic or other tools, be sure to keep them covered
unless otherwise specified.
Never touch the drive units when operating them using the Diagnostic or other
tools. Be sure to observe the procedures in this manual.
6)
Avoid burns by not touching any fusing components until they have had sufficient time to cool
down.
