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 46 .
2. Check that you are using appropriate print-quality settings for your purposes (see Printing
on page 52 ). 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 178 .
4.
If the printheads are working correctly, go to the front panel and press and then to see
the paper advance calibration status. If the status is DEFAULT, try performing paper advance
calibration: see Recalibrate the paper advance on page 161 .
If the problem persists despite all the above actions, contact your customer service representative for
further support.
