Horizontal lines across the image (banding)
If your printed image suffers from added horizontal lines as shown (the color may vary):
1. Check that the paper type you have loaded corresponds to the paper type selected in the front panel
and in your software. See
View information about the paper on page 42.
2. Check that you are using appropriate print-quality settings for your purposes (see
Printing on page 50).
In some cases, you can overcome a print-quality problem merely by selecting a higher print-quality
level. For instance, if you have set the Print Quality slider to Speed, try setting it to Quality. If you
change the print-quality settings, you may wish to reprint your job at this point in case the problem has
been solved.
3. Print the Image Diagnostics Print. See
The Image Diagnostics Print on page 141.
4.
If the printheads are working correctly, go to the front panel and press
, then , then Image-
quality maintenance > Calibration Status to see the paper advance calibration status. If the status is
DEFAULT, try performing paper advance calibration: see
Recalibrate the paper advance on page 127.
If the problem persists despite all the above actions, contact your customer service representative for
further support.
