Horizontal lines across the image (banding)
If your printed image suers from added horizontal lines as shown (the color may vary):
1. Check that the paper type loaded corresponds to the paper type selected in the front panel and in the
software.
2. Check that the customer is using appropriate print-quality settings for the purpose. 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.
3. Print the print-quality diagnostic report. See General print-quality troubleshooting on page 133.
4. If the printhead is working correctly, perform paper advance calibration, see the user's guide.
If the problem persists despite all the above actions, contact your customer service representative for further
support.
Lines are too thick, too thin or missing
1. Check that the paper type you have loaded corresponds to the paper type selected in the front panel and
in your software.
2. Check that you are using appropriate print-quality settings for your purposes. Select the custom print-
quality options in the driver dialog, and try turning on the Maximum detail option (if available).
3. If the resolution of your image is greater than the printing resolution, you may notice a loss of line
quality. You can nd the Max. Application Resolution option in the driver dialog's Advanced tab, under
Document Options > Printer Features.
4. If lines are too thin or missing, print the print-quality diagnostic report. See General print-quality
troubleshooting on page 133.
