    • Replacement provides a new OPC.
    • Cartridges are often packaged to prevent sunlight exposure.
    • Procedure involves powering off the printer, opening it, removing the old cartridge, and installing the new one.
    • Remove all packing materials.
    • Keep protective covers in place to prevent light from reaching the OPC drum.
    • Cartridges can be inserted from the side or top of the printer.

Laser Printer Maintenance Kit

  • Maintenance Tasks:
    • Laser printers have many moving parts.
    • Maintenance kits contain replacement parts like feed rollers and fuser units.
  • Frequency:
    • Manufacturers advise on maintenance timing often based on printed pages.
    • Printers have internal counters that track the number of printed pages.

Printer Maintenance Procedures

  • Safety Precautions:

    • Always power off and remove the power source before working inside the printer.
