 For details about attaching the Z-fold support tray for multi-folding unit, see the user manuals
that come with the machine.
 If the Z-fold support tray for multi-folding unit is attached, the trailing edge of the ejected
sheets will not be too close to the paper exit, so no problem will occur. However, the stapled
sheets may not be stacked properly.
Leading Edge is Curled, or J107/109 Occurs Due to Curling
Large size long-grain paper of Thickness 1 (52.3 to 63 g/m2) or large size short-grain paper of
Thickness 2 (63.1 to 80 g/m2) may curl when delivered. If the amount of concave curling is large (at
around 15 mm of the maximum acceptable value), the leading edge of the delivered sheet may float
and curl upward.
Once this happens, the subsequent sheets will hit against the curled sheet, causing a jam at the paper
exit (JAM107/109).
Cause
This is likely to occur if:
 Paper of Thickness 1 or 2 (52.3 to 63 g/m2), A3 size or larger is used
Output sheets bend upward.
This occurs when the height of curl is around 15 mm.
Solution
Correct the curl to the opposite side (convex curling) by using the decurl unit. Doing so decreases the
height of curl to 10 mm or less, and prevents output sheets from floating and bending upward.
In "Adjustment Settings for Operators", specify No. 0310 "Correct Output Paper Curl" and correct the
curl. (SP1-906-001 to 7: De-curler Setting)
