ASSEMBLY/DISAEEMBLY PRECAUTIONS
Replace with recommended parts. Take care to note the exact location of parts and
correct cable routing before you disassemble any part of the machine. Ensure all
parts and cables are replaced correctly. Do the following procedures before you
disassemble the printer or replace any parts.
1. Check the contents of the
machine memory and make a
note of any user settings. These
will be erased if the mainboard or
network card is replaced.
2. Ensure that power is
disconnected before you service
or replace any electrical parts.
3. Disconnect printer interface
cables and power cables.
4. Only use approved spare parts.
Ensure that part number, product name,
voltages, current or temperature rating
are correct.
5. When removing or re-fitting any
parts do not use excessive force,
especially when fitting screws into
plastic.
6. Take care not to drop any small
parts into the machine.
7. Handling of the OPC Drum.
• The OPC Drum can be damaged
if it gets exposed to light.
• Take care not to expose the OPC
Drum either to direct sunlight or
to fluorescent or incandescent
room lighting. Exposure for as little as 5 minutes can damage the surface's
photoconductive properties and will result in print quality degradation.
Remove the OPC Drum and store it in a black bag or other lightproof
container. Take care when working with the covers (especially the top cover)
as light is admitted to the OPC area and can damage the OPC Drum.
• Take care not to scratch the green surface of OPC Drum Unit. If the green
surface of the Drum Cartridge is scratched or touched the print quality will be
compromised.
