Cleaning the Corona Wires
Most Brother and some Dell, HP and Lexmark laser or LED printers employ a print engine design that separates the drum unit from the toner cartridge in order to keep the operating cost down for the customers. You would usually need to clean the corona wires when you replace the toner cartridge, and you would usually need to reset the drum counter when you replace the drum unit. Please follow the instructions on your printer manual or contact us for more information.
Replacing the OPC Drum
The OPC drum inside the toner cartridge or in the separate assembly unit is light sensitive. If you need to take it out from the printer before you need to replace it for whatever reason, please cover it carefully with paper or cloth.
Protecting Your Printer in the Winter
The weather in Calgary could be very harsh in the winter. When you bring a cartridge indoor, please let the cartridge warm up to room temperature before installing it in your printer. Otherwise, condensation could form inside the cartridge, affecting its operation and print quality. Try to place your printers away from a window or air vent. Any abrupt change in temperature and/or humidity could affect the normal operation of your printer.
