This article will help you confirm the problem. Please refer to the directions in the table below to help determine which hardware part is causing the issue.
Steps Actions 1 To determine the source of such print defect, verify if all of the Developers Units (DU) are installed. If all DUs are installed, remove them from the printer, shake each unit gently from side to side while holding them in a horizontal position, and then re-install them back into the printer. 2 If DU removal/re-seating does not correct the issue, replace them with new supplies. If you have no DU replacement supplies in stock, please contact Lexmark Technical Support for other troubleshooting suggestions.
Please contact Lexmark Technical Support if you need additional assistance. NOTE: When calling for support, you will be asked for your machine/model type and serial number (SN). If you need help locating your printer's model type and serial number, click here.
