Troubleshooting Paper Abrasion and Blurry Images
The print head height setting affects printing quality.
Specifying a low print head height makes images clearer and enhances printing quality but may cause paper
to rub against the print head.
On the other hand, specifying a high print head height will prevent paper from rubbing against the print head
but may reduce the printing quality.
Important
• Paper rubbing against or becoming caught on the print head may jam or result in printed documents
that are soiled.
Note
• Raise or lower print head, depending on nature of the problem.
