Setting the positions of drive wheels and hubs
Place the back-stop on to the adjustable side lay and slide up towards the paper stack
allowing a gap (as specified in the above step) before clamping. When the extension table
is used for feeding longer sheets, remove clamp type back stop and use the magnetic
type back stop as shown in fig. 18.2.
Depending on the length of the sheet to be creased, the air distribution knob can be
rotated to various positions in order to supply air to different ports. Position 1 is
recommended for most sheet sizes. However, a better result may be obtained by using
the below settings or by experimentation.
1 - For A5 sheets or 8 inches long, port 1 open.
2 - For A4 sheets or 11 inches long, front port and port 2 open.
3 - For A3 sheets or 17 inches long, front port and port 3 open.
0 - For longer sheets in order to supply air to the centre of the stack, port
2 open
To control the amount of air supplied to the ports, the air separation knob can be rotated
clockwise to decrease the pressure or anti-clockwise to increase the pressure..
It is important that the drive wheels and drive hubs on the roller shafts are arranged evenly
across the width of the media being creased. This is done to ensure that the media is
accurately driven and supported through the rollers.
The drive wheels and hubs are fixed to the rollers by means of a grub screw. To locate this
grub screw the rollers can be rotated by operating the motor manually.
Position
DO NOT ROTATE THE DRIVE ROLLERS BY HAND.
