Assembly / Disassembly Precautions
Replace parts carefully, always use Xerox parts. Take care to note the exact location of parts and
also cable routing before dismantling any part of the machine. Ensure all parts and cables are re-
placed correctly.
Please carry out the following procedures before dismantling the machine or replacing 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 is replaced.
2. Ensure that power is disconnected before servicing or replacing any electrical parts.
3. Disconnect printer interface cables and power cables.
4. Be sure to remove the print cartridge before you disassemble any parts.
5. Only use approved spare parts. Ensure that part number, product name, any voltage, current
or temperature rating are correct.
6. When removing or re-fitting any parts do not use excessive force, especially when fitting
screws into plastic.
7. Take care not to drop any small parts into the machine.
8. Handling of the OPC Drum
- The OPC Drum can be irreparably damaged if it exposed to light.
Take care not to expose the OPC Drum either to direct sunlight or to fluorescent or incandes-
cent room lighting. Exposure for as little as 5 minutes can damage the surface’s photocon-
ductive properties and will result in print quality degradation. Take extra care when servicing
the machine. 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) open 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.
