Regular Maintenance

• Clean the inside of the Laser Printer each time the toner cartridge or drum is changed (see the Printer User Guide for where to clean and how to clean).
• Clean the Corona wire each time the drum is changed (see Printer User Guide).

When the printer is new, or has freshly installed consumables and has been cleaned, print a "Windows Test Print". Keep this for future reference, out of the light. There is then a reference point for printing at any time so that print quality can be assessed. If the present quality is lower, clean the printer first, and if that fails to restore the quality, check the consumables, and replace if necessary.

Refer to the manufacturer’s Printer User Guide if any diminution of print quality is detected at any time, and follow their guidelines for rectifying the problem.
