Depending on the issue, change the Feed Priority setting for the particular type of paper. (See "Selecting a Feed Amount Adjustment Method (Feed Priority) .") →P.676 2. Based on the Feed Priority setting, use Auto Band Adj. , Manual Band Adj , or Adjust Length . (See " Auto Band Adjustment (Auto Band Adj.).") →P.677 (See " Manual Band Adjustment (Manual Band Adj).") →P.678 (See "Adjusting Line Length (Adjust Length) .") →P.681 3. If additional fine-tuning is necessary after Auto Band Adj. or Manual Band Adj , use Fine Band Adj. in the Menu Durng Prtng . (See "Banding Adjustment During Printing (Fine Band Adj.) .") →P.680 Selecting a Feed Amount Adjustment Method (Feed Priority) Methods of adjusting the amount paper is fed are set for each type of paper, in the Feed Priority setting. Adjust the Feed Priority setting to suit your particular printing application. • Band Joint : Adjusts the feed amount to reduce banding across the sheet in printed documents. The settings of Auto Band Adj. or Manual Band Adj are applied. If you have executed Fine Band Adj., in addition to the settings of Auto Band Adj. or Manual Band Adj, the settings of Fine Band Adj. are also applied. • Print Length : Adjusts the feed amount for better accuracy of lines in printed documents. The settings of A:High or B:Standard/Draft in the Adjust Length menu are applied. • Automatic : Band Joint or Print Length is selected, depending on Print Priority as selected in the printer driver at the time of printing. Image or Office Document : Band Joint is selected. Line Drawing/Text : Print Length is selected.

If printed images are affected by banding in different colors, adjust the amount that paper is fed. Auto Band Adj. offers two modes, Standard Adj. and Advanced Adj. . Use Advanced Adj. if Standard Adj. does not eliminate banding, or when using paper other than genuine Canon paper or paper for purposes other than checking output. Always check the Feed Priority setting before using Auto Band Adj.. (See "Selecting a Feed Amount Adjustment Method (Feed Priority) .") →P.676 Note • When using highly transparent media not compatible with Auto Band Adj., you must adjust the feed amount manually. (See "Manual Band Adjustment (Manual Band Adj) .") →P.678 • If additional fine-tuning is necessary after Auto Band Adj., use Fine Band Adj. . (See " Banding Adjust- ment During Printing (Fine Band Adj.) .") →P.680 • To adjust the measurement scale and ensure accuracy (so that lines in CAD drawings are printed at exactly the right length, for example), specify the amount of paper stretching or shrinkage when adjusting the feed amount. (See "Adjusting Line Length (Adjust Length) .") →P.681 • 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.

Banding Adjustment During Printing (Fine Band Adj.) If, during printing, the contrast is uneven sideways across the paper or banding in different colors appears at 50 mm (2 in.) intervals, try adjusting the feed amount as follows. The results of adjustment are applied to printing in progress, enabling you to check the results immediately. However, note that because printing is paused, colors may be slightly different. Use Fine Band Adj. after Auto Band Adj. or Manual Band Adj if finer adjustment is required. (See "Auto Band Adjust- ment (Auto Band Adj.) .") →P.677 (See "Manual Band Adjustment (Manual Band Adj) .") →P.678 Note • The Fine Band Adj. value is reset to 0 if you use Auto Band Adj. or Manual Band Adj .
