Troubleshooting Paper Abrasion and Blurry Images iPF785 Troubleshooting Paper Abrasion and Blurry Images The Printhead height setting affects printing quality. Specifying a low Printhead height makes images clearer and enhances printing quality but may cause paper to rub against the Printhead. On the other hand, specifying a high Printhead height will prevent paper from rubbing against the Printhead but may reduce the printing quality. • Paper rubbing against or becoming caught on the Printhead may jam or result in printed documents that are soiled. Important • Raise or lower the printhead, depending on the nature of the problem. Note (See "Paper rubs against the Printhead.") ➔P.639 (See "The edges of the paper are dirty.") ➔P.640 (See "Image edges are blurred or white banding occurs.") ➔P.643 1 On the Tab Selection screen of the Control Panel, press ◀ or ▶ to se- lect the Paper tab ( ). Adjustments for Better Print Quality Adjusting the Printhead • If the Tab Selection screen is not displayed, press the Menu button. Note 2 Press the OK button. The Paper Menu is displayed. 3 Press ▲ or ▼ to select Paper Details, and then press the OK button. 4 Press ▲ or ▼ to select the type of paper, and then press the OK button. • When Head Height is set to Automatic, the setting value selected for the previous print job is displayed (to the right of Automatic ) Note once you select the type of paper currently supplied. However, the value is cleared when the printer is turned off or the paper is replaced. 5 Press ▲ or ▼ to select Head Height, and then press the OK button. 6 Press ▲ or ▼ to select the desired setting value, and then press the OK button. • Using Automatic will ensure that the printer adjusts the Printhead height to the optimal level before printing, Note accounting for the ambient temperature and humidity. When a setting other than Automatic is used, that value will always be applied. • Depending on the type of paper, some setting values may not be available. 578 User's Guide
