AcuLaser C1100, CX11N & CX21N: Gap, gaps or "white lines" in the print


  • One or more gaps or white lines all the way down or across the page.
  • Portrait orientation: the lines or gaps are vertical (often towards the right).
  • Landscape orientation: the lines or gaps are horizontal (often towards the bottom).
  • AcuLaser C1100, CX11N, CX21N and all variants.


Vertical or horizontal gaps in the print occur when the laser lens is obstructed.

There are two main causes:

  1. Toner has spilled onto the lens, for example during toner cartridge replacement.

  2. One or more toner cartridges are not fully locked.

To resolve this issue, clean the print head. If the problem remains, you will need to locate and clean up any spilled toner, and may need to reinstall a toner cartridge.
