6.4.2 Printing a cleaning sheet
If you are experiencing blurred, faded or smeared printouts. Printing a cleaning sheet cleans the drum
inside the toner cartridge. This process will produce a page with toner debris, which should be discarded.
1) Ensure that the printer is turned on and in the Ready mode with paper loaded in the tray.
2) Press and hold down the Cancel button on the control panel for about 10 seconds.
3) Your printer automatically picks up a sheet of paper from the tray and prints out a cleaning sheet with
dust or toner particles on it.
Note:
The cartridge cleaning process takes some time. To stop printing, turn the power off.
