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 paper type that cannot be multi-folded is selected
When a combination of paper orientation and fold position that cannot be folded is selected.
When form feeding is used
When multifold is specified but the number of sheets exceeds the maximum number available for the multifold 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 Plain (64 g/m2 or less), Thick (more than 103 g/m2), Letterhead, Translucent, OHP Transparency, Cardstock, Labels, and Tab Stock.
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.
Slip sheets, punch, staple, booklet staple (only when booklet staple is specified with Finisher SR 4040), and auto tray switching functions cannot be used when folding.
When the fold function is used, Rotate 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.
