Print cartridge conditions
Using the printer cleaning page
Note To ensure good print quality with certain types of paper, use the cleaning page every time the print
car tridge is replaced. If the cleaning page is frequently needed, try a different type of paper.
If toner specks appear on the front or back side of your print jobs, follow the procedure below.
From the printer control panel:
1 Use or to select Config Device and press .
2 Use or to select Print Quality and press .
3 Use or to select Create Cleaning Page and press .
4 When toner has been cleaned from inside the printer, shiny black spots will appear on the page black
strip. If white spots appear on the black strip, print another cleaning page.
Note In order for the cleaning page to work properly, print the cleaning page on copier grade paper (not
bond or rough paper).
Shaking the print cartridge
When you install a print car tridge for the first time, gently shake it from side to side to distribute the toner
evenly inside the car tridge. Due to the new cartridge design, this is the only time you will need to shake the
car tridge.
