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.
The originals are folded or wrinkled.
Solutions
❏ When using the ADF
Do not place the originals on in ADF. Place the originals on the scanner glass instead.
❏ When using the scanner glass
Flatten out the folds and wrinkles in the originals as much as possible. When placing originals, try
placing a piece of card and so on over the document so that it does not lift up, and remains in close
contact with the surface.
