Banding in all of the colors
NOTE In high quality modes media advance problems may not appear
as lines of banding, they may appear grainy instead. The banding
or graininess will appear in all the colors.
1 If the image is grainy, this could also be a symptom of problems
with the bidirectional alignment (See Solving Bidirectional Alignment
Problems 6-12
). If the Bidirectional Alignment pattern has no
problems go to step two.
2 Make sure that the media selection made in the front panel is the
same as the media that you have loaded.
3 It is possible that the banding was caused because the customer was
using non-HP media. If the customer still wants to use non-HP
media, recalibrate the paper accuracy by performing the User’s
Accuracy calibration and NOT the Service Accuracy Calibration
(Refer to the User’s Guide). Performing this will overwrite the
default setting for only the paper that you have selected.
4 Perform the Printheads alignment procedure (Refer to the User’s
Guide).
NOTE For high production modes, use the Banding Calibration Page
5-44.
