Repeating defects

Note:  Before solving the problem, print the Print Quality Test Pages. From the control panel, navigate to Settings > Troubleshooting > Print Quality Test Pages. For non‑touch‑screen printer models, press to navigate through the settings.


Step 1

  • Using the Print Quality Test Pages, check if the distance between the repeating defects is equal to any of the following:
  • Imaging unit

    • 96  mm (3.78  in.)
    • 37.7  mm (1.48  in.)

    Toner cartridge

    • 43.5  mm (1.71  in.)
    • 37.5  mm (1.48  in.)

    Transfer roller

    • 52  mm (2.05  in.)


    • 79.8  mm (3.14  in.)
    • 62.5  mm (2.46  in.)

Does the distance between the repeating defects match the toner cartridge or imaging unit measurements?

Go to step 2.

Note:  If the repeating defects match the transfer roller or fuser measurements, then contact customer support.

Take note of the distance, and then contact customer support.

Step 2

  1. Replace the affected supply item.

  2. Print the document.

Do the repeating defects appear?

Contact customer support.

The problem is solved.
