Solving Problems
Blurry Copies, Vertical Banding, or Misalignment
The following causes can be considered.
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.
Bidirectional printing is enabled.
Solutions
If the print quality does not improve even after aligning the print head, select Settings > Printer Settings
on the control panel and then disable Bidirectional.
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.
Printout Comes Out as a Blank Sheet
The print head nozzles may be clogged.
Solutions
Perform the nozzle check, and then try Power Cleaning if the print head nozzles are clogged.
