Blurry Prints, Vertical Banding, or Misalignment

The following causes can be considered. Check the causes and follow the solutions in order from the top.

The print head position is out of alignment.

Solutions

Select the Maintenance > Print Head Alignment > Vertical Alignment menu on the control panel to align the print head.

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.

  • Windows

    Clear Bidirectional Printing on the printer driver’s More Options tab.

  • Mac OS

    Select System Preferences from the Apple menu > Printers & Scanners (or Print & Scan, Print & Fax), and then select the printer. Click Options & Supplies > Options (or Driver). Select Off as the Bidirectional Printing setting.
