Notes on the fold function

Follow these precautions when using the fold function.

Conditions where fold function will be canceled

When a paper type that cannot be folded is selected. ^*1
When a paper size that cannot be folded is selected.
When a combination of paper orientation and fold position that cannot be folded is selected.
When the machine is made to continue printing manually.
When fold is specified but the number of sheets exceeds the maximum number available for the fold function.
If there are inconsistencies between the orientation in duplex mode and the fold position.
When [Auto Continue] is set.
When the paper is fed from an optional interposer tray.
When multifold is specified but the paper sizes are different.
^*1 The fold function is not supported for Thick 1 to 3, Letterhead, Translucent, OHP Transparency, Cardstock, Labels, and Tab Stock.

This function is also available using the PostScript 3 printer driver. For details, see PostScript 3 Supplement.
To use the Z-fold function, you must set the Z-fold support tray. For details about how to set the Z-fold support tray, see "When Z-folded Paper Is Not Properly Aligned", Troubleshooting.
Folded copies that are delivered to the Multi-Folding Unit tray may be stacked with their folds open. If this happens, the position of the folds is unaffected and the copies will still be output in sequential order. Stacked copies can be easily separated in the order they were delivered. To prevent their folded sections overlapping, configure the machine to deliver folded copies to the Finisher upper tray or Finisher shift tray.
Remove the Z-fold support tray when delivering copies to the shift tray without using the Z-fold function. If you leave the Z-fold support tray in place, prints are not stacked properly.
Fold function is disabled when printing using the bypass tray.
Fold function is disabled when 1200 dpi is selected in [Resolution:] in the printer driver.
Slip sheets, punch, staple, booklet staple (only when booklet staple is specified with Finisher SR4040), and auto tray switching functions cannot be used when folding.
When the fold function is used, Rotating Collate will be canceled.
When stapling Z-folded paper, fewer sheets than normal can be stapled together. This is because a single Z-folded sheet is equivalent to 10 non-Z-folded sheets.
Depending on the temperate and humidity conditions of the machine's environment and the type of paper being folded, use of the fold function can cause toner smearing, which can occasionally result in spoilt prints.
Wrinkling can occur when applying letter fold-out to B4 JIS, A3, 8¹/₂14, 1117, 12 18, 8K, or larger sheets. In some cases, you may have to use A4 sheets or smaller when applying folds in combination with the reduction function.
Print quality over fold lines might be reduced. This is due to cracking within the fused toner. Loss of surface along fold lines can also occur with some types of paper. To avoid possible wastage, print a single test sheet before beginning a print run.
Printing will stop if the number of printed sheets exceeds tray capacity. If this happens, remove printed sheets from the folding unit tray to resume printing.
Coated paper cannot be used with the Multi-sheet Fold function.
The Multi-sheet Fold function can fold a maximum of three sheets at a time.
