one or more colors are absent or much weaker on a printed DeviceOK color test
If the live test passes, the investigation can usually move away from total hardware failure and toward the affected app, permissions, routing or configuration.
Try the simple causes first
- 1
Print the DeviceOK color test page again using normal/default quality.
- 2
Confirm the printer reports usable ink/toner for the missing color.
- 3
Check whether the problem appears in another document or built-in printer test.
Work through the problem in order
- 1
Run the DeviceOK color print test and note exactly which color or region is missing.
- 2
Verify ink/toner status and that cartridges/tanks are correctly seated and recognized.
- 3
Use the printer manufacturer's own nozzle/print-quality diagnostic or maintenance function when available.
- 4
Confirm the correct paper type and normal print quality are selected.
- 5
If the same color remains absent across independent test pages, follow the manufacturer's official maintenance/support path rather than repeatedly cleaning without guidance.
If the DeviceOK test prints all colors correctly, focus on the affected document, application, color-management setting, or print preset rather than assuming a printer hardware fault.
If a controlled DeviceOK test and the printer's own diagnostic both show the same missing color, the printer-side ink/toner/printhead path becomes more likely.
