(See "Enhancing Printing Quality.")→P.728 Troubleshooting Paper Abrasion and Blurry Images 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. Important•Paper rubbing against or becoming caught on the Printhead may jam or result in printed documents that are soiled. Note •Raise or lower the printhead, depending on the nature of the problem.

Priority to suit the particular type of paper. (See " Selecting a Feed Amount Adjustment Method .") →P.737 2 Execute Adj. Quality or Adjust Length , depending on the selection in Adj. Priority. (See " Automatic Banding Adjustment .") →P.738 (See " Manual Banding Adjustment .") →P.739 (See " Adjusting Line Length .") →P.742 3 After executing Adj. Quality, execute Adj. Fine Feed for further adjustment as needed. (See " Fine-Tuning the Paper Feed Amount .") →P.741 Selecting a Feed Amount Adjustment Method Selecting a Feed Amount Adjustment Method There are two methods of adjusting the paper feed amount, Print Quality and Print Length , either of which will be applied during printing. Since the method that is applied during printing is determined from the value of the Adj. Priority setting, configure the Adj. Priority to match the print target. • Print Quality : Adjusts the feed amount to reduce banding across the sheet in printed documents. Adj. Quality settings are applied. When Adj. Fine Feed is executed, the Adj. Fine Feed settings are applied in addition to the Adj. Quality settings. • Print Length : Adjusts the feed amount for better accuracy of lines in printed documents. The settings of A:High or B:Standard/Draft in Adjust Length are applied. • Automatic : Print Quality or Print Length is selected, depending on Print Priority as selected in the printer driv- er at the time of printing. Note •Either A:High or B:Standard/Draft in the Adjust Length menu is applied, depending on printer driver settings at the time ofprinting. Follow these steps to configure the settings. 1 Load the paper. • Loading Rolls on the Roll Holder→P.531 • Loading Rolls in the Printer→P.534 • Loading Sheets in the Feed Slot→P.554 iPF6400 Adjusting the Feed AmountUser's Guide Adjustments for Better Print Quality Adjusting the feed amount 737

Automatic Banding Adjustment Automatic Banding Adjustment If printed images are affected by banding in different colors across the sheet, execute Adj. Quality for automatic ad- justment of the paper feed amount. There are two modes of automatic adjustment to correct banding: Auto(GenuinePpr) and Auto(OtherPaper) . In either mode, the printer prints and reads a test pattern for automatic adjustment of the feed amount. • Auto(GenuinePpr) Use this mode with paper identified in the Paper Reference Guide. (See " Types of Paper .") →P.524 • Auto(OtherPaper) Use this mode with paper not in the Paper Reference Guide, or if Auto(GenuinePpr) does not eliminate banding. (See " Types of Paper .") →P.524 Important•Adjustment is not possible with Auto(GenuinePpr) and Auto(OtherPaper) when using highly transparent media.In this case, use Manual adjustment. (See "Manual Banding Adjustment.")→P.739 Note •We recommend executing the adjustment if you have changed the paper type or paper size.•Always check the Adj. Priority values before using Auto(GenuinePpr) or Auto(OtherPaper). (See "Selecting a Feed Amount Adjustment Method.")→P.737•If additional fine-tuning is necessary after Auto(GenuinePpr) and Auto(OtherPaper), execute Adj. Fine Feed. (See "Fine-Tuning the Paper Feed Amount.")→P.741•Use Adjust Length to ensure that lines in CAD drawings are printed at exactly the right length. (See "Adjusting Line Length.")→P.742•This may take some time, depending on the type of paper.
