For a print quality defect of this type, it is always advisable to print the following:
- Menu Settings Page – To check the levels of the consumable supplies (i.e., items such as photoconductor units, developer units and toner cartridges), because supplies that are low or near the end of their functional lives can cause various print quality issues independently of printer operation.
Note: The User's Guide provides detailed instructions for navigating through the printer menus.
Remove the combo pack with the affected color and then replace the photoconductor unit. If the issue persists after photoconductor unit is replaced, then replace the developer unit.
Note: If the print defect results in a colored background with a missing colored plane, skip to step 5 for additional troubleshooting.
If issues persists, place a piece of tape under the combo pack so it will block the photoconductor from the printhead beam, and then insert the combo pack back into the printer.

Note: The tape must not cover the channel or it may be torn off as you slide the combo pack back into the printer.
Print the Menu Settings Page and check to see whether the background is void where the tape was placed on the combo pack.
