7.2.1 Adjustment of Feeding Table Thrust
Release the feeding table by pressing the table release button (15) and set the table thrust regulation screw
(14) to minimum thrust. In "SETTING" Screen (Fig. 20) hold
MOVE ROLLERS
key with one hand and at
the same time use your second hand to gradually increase the feeding table thrust with the table thrust
regulation screw (14) until the feeding wheels has fed the sheet into the machine. The minimum feeding
table thrust is now set. Do not increase the feeding table thrust when not necessary, to eliminate possible
tracks on paper caused by the feeding wheel. The table thrust scale (27) helps you to adjust the thrust
precisely. Especially for the lower paper grammage, it is better to use less thrust, so as not to deform
paper.
7.2.2 Correct Placement of Paper Pile
When the table thrust is correctly adjusted, the feeding table can be loaded with a pile of paper up to the
maximum capacity of the feeding table. The pile of paper to be processed must be leafed through properly
before it is placed on to the table to minimize the possibility of feeding several sheets at once. The sheets
must be fed into the machine individually. Ideally, there is approx. a 2 mm gap between the sheets. The
sheets cannot overlap when fed into the machine. If the sheets overlap, tilt the paper brakes (7) down onto
the end of the sheet – approx. 1 to 2 cm from the end of the sheet. First tilt the paper brakes (7) without
weight, then increase it gradually until the sheets are fed into the machine individually with approx. a 2 mm
gap. Do not increase the weight on the paper brakes to eliminate possible tracks on the paper caused by
the feeding wheel and by the wheel of the auxiliary feeding head. After adjustment lock the paper brakes
(7) with the locking bolt of the brakes (32). Now press the
START
.. Ideally, if the feeding table is
adjusted correctly, the auxiliary feeding head (10) is not working and the sheets are fed into the machine
only by the friction system.
If the machine feeds two or more sheets at once, the machine must be stopped immediately by pressing
„STOP" (8). The sheets that have been fed into the machine must be taken out using the "MANUAL
CONTROL" Screen (
) and icons
by
MOVE ROLLERS
(Section 8.8). If the cycle was interrupted
when the tool stopped in the lower position, it is necessary to return the tool into the top position using the
UPPER TOOL
icon
from the "MANUAL CONTROL" Screen.
