Cyan, Magenta, Yellow, Black Genuine 4-Pack Toner Cartridge 1 x 1,420; 3 x 1,330 pages
The Color LaserJet Pro MFP M277c uses a single toner cartridge, HP CF400AQ1 (HP 201A).
The "Supply Problem" notice on the Color LaserJet Pro MFP M277c is typically a recognition fault on one of the colour cartridges, not a defect. Switch off for 30 seconds, reseat the reported cartridge, clean its contacts with a dry cloth, and power back on. If nothing changes, replace the cartridge for the colour the printer flags.
These quick tips apply to all laser printers. While your exact model may look slightly different, the steps are identical.
