10. Troubleshooting
Replacing the toner cartridge
•
X740x/750x/760x series uses four colors and has a different toner cartridge
for each one: yellow(Y), magenta(M), cyan(C), and black(K).
•
K740x/750x/760x/765x series uses one color and has a toner cartridge for
black(K).
When the toner cartridge is totally empty
•
The status LED turns red on and the display screen shows the error message
of replacing toner.
•
The machine stops printing and incoming faxes are saved in memory.
However, when the color toner cartridges are empty, but there is toner left
in the black toner cartridge, you can still print black-and-white print jobs
(the submitted job must be in black and white).
•
Check the type of the toner cartridge for your machine (see "Consumables
and Accessories" on page 208
)
.
At this stage, the toner cartridge needs to be replaced.
