Random bubbles or streaks of toner on every printed page.
A defective Photoconductor Unit (PCU) could cause this type of print defect. Therefore, it is always recommended to verify the same results from a different PCU. If the result is the same or should you not have an extra PCU to test, contact Lexmark Technical Support to set up service for the printer.
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 these, click here.
Please call from near the printer in case the technician on the phone asks you to perform a task involving the printer.
