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 of
printing.
Follow these steps to configure the settings.
