Banding in all of the colors

1Make sure that the media selection made in the front panel is the same as the media that you have loaded.

2It 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 accuracy calibration. Performing this will overwrite the default setting for only the paper that you have selected.

NOTE:If the customer wants to use HP certified paper at a later stage, they can restore the optimal setting to what it was by going to Utilities/Calibration/ Accuracy/Restore Factory.

3Perform the printheads alignment procedure.

NOTE

Aligning the Printheads

The printhead alignment selection causes the printer to align the printheads immediately, or if an image is being printed, as soon as the current print job is finished. The alignment procedure requires a minimum paper size of A2 or C-size.

The printer will automatically perform an alignment when printheads are replaced. You can use this feature if the Print Quality Print indicates an alignment error.

You should not attempt to align the printheads with tracing paper, vellum or clear film.
