Correction of skewed folds:
A skewed fold will result if the paper has not been fed exactly at right
angles with respect to the fold rollers.
To correct a skew, the entire feed table can be moved left or right by
turning the skew adjustment knob (1).
A pointer (2) in the slot above the knob will show which way the deck is
moving when turning the knob. As a general rule, the pointer should be
in the centre of the slot.
To correct a skewed fold:
• Remove the paper from the feed table.
• Turn the skew adjustment knob to centre the pointer in its slot.
• Reload the paper making sure there isn't too much clearance
between the stack and the side guides.
• Set the machine for a half (single) fold. This makes it easier to
determine which way to turn the skew adjusting knob.
• Run a trial piece.
• If the fold is skewed, compare your sample with the drawings
below:
If the sample looks like A, turn the skew adjustment knob
anticlockwise slightly.
If the sample looks like B, turn the skew adjustment knob
clockwise slightly.
• Remove and reload the paper stack. This is important – if you
do not reload the stack the adjustment you just made may not
take effect immediately.
• Run another trial piece and readjust if necessary.
Fine tuning the feeder
The fine tuning feature allows you to adjust the feeder gap (the opening
through which the paper must pass) in small steps while the machine is
running.
This is helpful with some "problem" papers, especially light-weight
recycling papers and heavy stock when the standard feeder settings tend
to mark the coated surface of the paper.
Observe the paper feed while folding. If the feeding is erratic (paper
seems to hesitate before entering the folder), or if you get "FAIL TO
FEED" messages, check first whether the pressure roller is exerting
enough pressure on the paper (see page 9 for details). If more pressure
does not help, you must open the feeder gap a little.
If you tend to get double sheets being fed, you must close the gap
slightly.
With the machine running, press the

A + symbol on the display shows you are opening the gap a little. A –
symbol on the display shows you are closing the gap a little.
By using the or keys, you can open or close the gap in steps
shown on the display by up to five + or – symbols. A typical display might
be:
: +++++
If no symbols show on the display, you are back to the standard feeder
setting.
To leave the fine tuning mode, press Enter. The display will switch back
to normal running mode.
If you don't press Enter, the machine will stay in fine tuning mode until
power is turned off. When the machine is turned back on again, the
display will be back in normal running mode.
Note: The paper thickness setting will not automatically change when
switching jobs. You must set paper thickness first when starting a new
job (see page 8). It is good practice to set paper thickness even when the
same weight of paper is used with the new job.
