Striped Patterns Appear

When printing on plain paper, 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.

Use the Print Quality Adjustment feature. If you have not used the printer for a long time, the print head nozzles may be clogged and ink drops may not be discharged.
