Follow the general workflow to solve quality problems and improve the output. The preconditions are that you:
Have performed maintenance regularly.
Perform automatic and manual maintenance with incidents, and perform periodic maintenance once a month or when the printer requests it. For more information, see Maintain the print quality.
Have calibrated the media.
All media types have to be calibrated first. Redo the calibration for every media width.
For more information, see Calibrate the media.
See a defect in a high pass mode: [High Quality] , [Specialty] , [Superior] , [Matte Quality] , [Matte Specialty] , [Backlit] or [Backlit Density] .

Do you see or experience... |
Solution |
|---|---|
|
a problem only or mainly visible in the 1st meter? |
Perform a media calibration, see Calibrate the media. |
|
regular, sharp, light lines? |
Perform maintenance including nozzle optimisation see Guidelines to maintain the print quality. |
|
a gradient within a swath? |
Try a robust print strategy or a slower print mode. See [Step correction] and print mode/strategy selection in Change the media settings. |
|
OD banding or lines within the swath boundary? |
Clean the platen and the buffer plate, see Clean the platen and Clean the buffer plate and redo a media calibration. |
|
problems regarding handling or application robustness? |
Contact your application specialist or look into the Media Verification Protocol. |
You can stop at any step when the issue is solved.
NOTE
Most important actions are clean the platen and clean the buffer plate.
In case the problem remains, use the printhead quality check chart to identify the issue and try to solve that specific quality problem. For more information, see Solve specific quality problems.
