If Banding Occurs This topic describes how to adjust the feed amount automatically. If printed images are affected by banding in different colors across the sheet, execute Adj. Quality for automatic adjustment 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. (→ , Types of Manuals) • Auto(OtherPaper) Use this mode with paper not in the Paper Reference Guide, or if Auto(GenuinePpr) does not eliminate banding. • Always check the Adj. Priority values before using Auto(GenuinePpr) or Auto(OtherPaper). (→"Selecting a Feed Amount Adjustment Method (Feed Priority)," User Manual) • Adjustment is not possible with Auto(GenuinePpr) and Auto(OtherPaper) when using highly transparent media. In this case, use Manual adjustment. (→"Manual Banding Adjustment (Adj. Quality)," User Manual) • If additional fine-tuning is necessary after Auto(GenuinePpr) and Auto(OtherPaper), execute Adj. Fine Feed. (→"Fine-Tuning the Paper Feed Amount (Adj. Fine Feed)," User Manual) • Use Adjust Length to ensure that lines in CAD drawings are printed at exactly the right length. (→ , If Line Length Does Not Match) • This may take some time, depending on the type of paper. • Use paper of the same type and size for adjustment as you will use for printing. Items to Prepare • Rolls An unused roll at least 10 inches wide • Sheets Auto(GenuinePpr): One sheet of unused paper, A4/Letter size Auto(OtherPaper): Two sheets of unused paper, A4/Letter size (or one sheet when using A2) Perform adjustment as follows. 1 Load paper.
