9) Paper is folded askew
-
Check the position of the side guides on the feeding table. If necessary, adjust the side guides using
the angle regulation screw, see Section 7.2.
-
Paper on the feeding table is bent. Use the magnetic strips to straighten paper, see Section 7.2.1.
-
The gap between the side guides and the paper pile is too big, see Section 7.2.1.
-
The auxiliary feeding wheels are not in the correct position, see Section 7.2.1.

doesn’t react and nothing happens while processing black or dark paper very likely sensor
on feeding table struggles to detect the paper. It is necessary to place on the top of the pile one sheet of
white or light paper.

After several months of use feeding wheels may wear down. If this happens the machine tends to feed
doubles because the gap between middle feeding wheel and separator (22) gets wider. The machine
feeds properly if the gap is between 0,05 and 0,1 mm. It is possible to prolong the lifespan of feeding
wheels by moving the shaft with the wheels downward. To do so we need to turn the fixing screw of
calliper (39) counter clockwise. Maximum turn is 3/4 of revolution. It is necessary to turn both screws on
both sides of the machine equally!
Fig. 34: Turn the fixing screw of calliper and move the shaft with feeding wheel downward. This will reduce the gap
between main feeding wheel and separator.
Fig. 35: The gap between feeding wheel and separator must be 0,05 – 0,1 mm wide.
