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.
