Gutter trim settings
Setting the gutter deflector knob
22
On certain jobs the gutter deflector needs to be engaged to move the scrap to the waste bin.
The knob has 2 positions.
Down is activated.
Up is deflector off.
There is an interlock on the knob flag to tell the machine in which setting they are positioned.
Silver pressure knob
24
At the top of the front cover is a silver knurled knob.
This has 5 positions as marked by the pips; 1 is lowest and 5 is highest.
The knob will vary and set the pressure on the front side of the 2 last feed rollers in the slitting area nearest the
blade and crease tool.
The setting requirement will vary with the following conditions.
- Paper thickness.
- Paper surface treatment un-calendered or calendered.
- Printed surface on the sheet , some printers use wax based toner that is more slippery.
- Cross cutting accuracy result.
Basically if the cross cutting is accurate then do nothing.
If the accuracy is not so good then you can try a harder setting to see if the grip improves.
Note that the pressure adjustment will not compensate for dirty rollers which must be perfectly clean to get the
right grip, clean them each day.
Interior mid roll pressure compensation knobs
25
In the machine there are 2 pressure knobs in front of and behind the cross blade that will counteract the warp of
the upper feed roll by adding pressure in the middle.
These are factory set and usually dont require any other adjustment.
If you see that the middle strip of cards is loosing grip then a slight increase ( clockwise )of the pressure may help
compensate.
Do not over do it as you may mark the rolls and void the warranty.
Note: the adjustment is minute 1/16 th turn is normally enough.
