Assembly/ Disassembly Precautions
Replace parts carefully, always use genuine 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 replaced correctly.
Please carry out the following procedures before dismantling the printer 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 main board or network card is replaced.
(2) Ensure that power is disconnected before servicing or replacing any electrical parts.
(3) Disconnect printer interface cables and power cables.
(4) Only use approved spare parts. Ensure that part number, product name, any voltage,
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
ƒ The OPC Drum can be irreparably damaged if it is 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 five minutes can damage the surface’s
photoconductive properties and will result in print quality degradation. Take extra care
when servicing the printer. 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.
ƒ 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.
