Replacing a Developer Cartridge
A message on the control panel window, X DEV LOW indicates
when it is time to change a developer cartridge. The x indicates
which color should be changed. Cyan, yellow, and magenta
developer cartridges last for approximately 15,000 pages, and
black developer cartridges last for approximately 30,000 pages.
NOTE: The industry standard for developer measurement is
quoted at 5% coverage for letter- or A4-size media.
To replace a developer cartridge, use the following procedure:
1. Remove the printer’s top cover (fig. 2.5).
2. Remove the toner cartridge by holding it across the center,
squeezing the sides to loosen the pins on the back side from
the developer cartridge notches (fig. 6.1). Then, lift the toner
cartridge straight up and out of the printer.
