Disable cartridge check
Use this diagnostic test to print internal pages or send an external job to the product when one or more toner
cartridges are removed or exchanged. Supply errors are ignored while the product is in this mode. When the
product is in this mode, access the troubleshooting menus and print internal pages (the print quality pages
will be the most useful). This test can be used to isolate problems, such as noise, and to isolate print-quality
problems that are related to individual toner cartridges.
NOTE: Cartridges are not keyed and can be interchanged. An error will display on the control panel if a
toner cartridge is installed in the wrong position. The Manage Supplies menu explains which toner cartridge is
misplaced.
Do not remove or exchange toner cartridges until after beginning the disable cartridge check diagnostic.
