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. To check on the front panel, use the View loaded paper key.
2. Check that you are using appropriate print-quality settings for your purposes (see
Printing
on page 43). 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 have already set it to Quality, try selecting custom options and then
More Passes. 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 155.
4. If the printheads are working correctly, go to the front panel and press the View loaded paper
key to see the paper advance calibration status. If the status is RECOMMENDED, you should
perform paper advance calibration: see
Recalibrate the paper advance on page 139.
If the problem persists despite all the above actions, contact your customer service representative for
further support.
