Print cartridge conditions
Using the product 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 product control panel:
1 Touch Menu.
1 Touch Configure Device .
2 Touch Print Quality .
3 Scroll to Create Cleaning Page .
4 Touch Create Cleaning Page , and the page automatically prints.
5 When toner has been cleaned from inside the product, shiny black spots appear on the page black strip. If white spots
appear on the black strip, print another cleaning page.
Note 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 cartridge.
