8. Handling Paper
8-1. Paper used
• Make sure that the printing ink on the paper has dried completely prior to use.
• Wet ink or ink that is not completely dried may stain the folding roller causing trouble such
as smearing on paper.
• Use of paper printed with special types of ink may cause the folding roller to swell or deform,
and folding misalignment may occur.
• Paper may not be fed smoothly into the folding plate or deformed folding may occur depending on
different environmental factors (temperature, humidity), paper ream weight, paper type, paper grain
direction if curled paper is used. Make sure to flatten curled paper or paper with folded lines before use.
• Separate the sheets of paper well before stacking them.
8-2. Precautions on stacking paper
[a]
[b]
[a] D
o not stack the sheets of paper on the paper
feed tray with the sides of sheets unaligned or
some sheets protruding from the stack.
This machine has an automatic standard
paper size detection function. It automatically
detects paper size at the paper feed guides.
Therefore, if paper is protruding out from the
left or right side, it is unable to detect paper
size accurately and may determine standard
paper as non-standard. (DF-999/DF-999A)
[b] Do not stack paper on the paper feed tray with
the lead and trail edges unaligned or some
sheets protruding out.
• Processing with sheets unaligned on the right or left side may cause such trouble as folding
misalignment and jamming.
• Processing with sheets unaligned on the lead and trail edges may lead to unstable feed
causing such trouble as miss-feed and double-feed.
