Blurry Copies, Vertical Banding, or Misalignment

The following causes can be considered.

The print head position is out of alignment.

Solutions

Align the print head using the Print Quality Adjustment feature.

The bidirectional printing setting is enabled.

Solutions

If print quality does not improve even after aligning the print head, disable the bidirectional setting.

During bidirectional (or high speed) printing, the print head prints while moving in both directions, and vertical lines may be misaligned. Disabling this setting may slow down printing speed but improve print quality.

Select Settings > General Settings > Printer Settings, and then disable Bidirectional on the control panel.
