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.
