Place the paper stack on to the loading table and slide up to the fixed side lay and paper
Gate. Release the clamps located at each end of the side lay and slide up towards the
paper stack as demonstrated in FIG 8.1. Allow a gap of approximately 0.5mm (1/64 inch)
between the paper and the side lay.
When using heavy stocks or large paper stacks, the feeding of the sheets may be improved
by fitting the Clamp Plates to the Adjustable Side Lay, as shown in FIG 8.2 below; but
please be aware that they may cause double feeding when using light stocks.
Position the backstop and slide up towards the paper stack allowing a gap (as specified
in the above step).
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 settings below or by experimentation.
For A5 sheets or 8 inches long, front port and port 1 open.
For A4 sheets or 11 inches long, front port and port 2 open.
For A3 sheets or 17 inches long, front port and port 3 open.
For longer sheets in order to supply air to the centre of the stack, port
1 and port 2 open.
To control the amount of air supplied to the ports, the air separation knob can be adjusted
by first rotating the knob to unlock its position, then push the knob down to the required
position and rotate the knob to re-lock its position.

Situated on the front of the feed table, the Vacuum Bleed Knob is used to allow more
control of the suction on the vacuum drum.
When light weight paper of 90gsm and lower is being fed through the machine turn the knob
clockwise to reduce the possibility of marking, or damage to the leading edge of the paper.
