Take any notes as instructed. You will need that information in the event you need to contact your next level support.
Note:
Before troubleshooting, determine the operating system used when the error occurred. If possible determine whether a PostScript or PCL file was sent to the device when the error occurred. Ask the customer which Lexmark Solutions applications are installed on the device.

Service tip: Before troubleshooting any print quality problems, do the following:
1.
Print a menu settings page, and then check the life status of all supplies. Any supplies that are low should be replaced.
Note:
Be sure and keep the original menu page to restore the customer's custom settings if needed.
2.
On the menu page, make sure the following is set to the default level:
–
Color Correction: Set to Auto.
–
Print Resolution: Set to 1200 dpi (print quality problems should be checked at different resolution settings).
–
Toner Darkness: Set to 4 (default).
–
Color Saver: Set to OFF.
–
RGB Brightness, RGB Contrast, RGB Saturation: Set to 0.
–
Color Balance: Select Reset Defaults to zero out all colors.
–
Check the paper type, texture and weight settings against what is loaded in the printer.
Once the printer has been restored to its default levels, do the following:
3.
Inspect the transfer module for damage. Replace if damaged.
4.
Inspect the photoconductor units and toner cartridges for damage. Replace if damaged.
5.
If paper other than 20 lb plain letter/A4 paper is being used, load 20 lb plain letter/A4 and print the Print
Quality pages to see if the problem remains.
6.
Use Tray 1 to test print quality problems.
7.
Print the Print Quality Pages, and then look for variations in the print from what is expected.
An incorrect printer driver for the installed software can cause problems. Incorrect characters could print, and the copy may not fit the page correctly.
Measure all voltages from the connector to the printer ground.
