Description of Operation
After the PSQ160 is turned on, the operator either enters the paper size and
direction on the GUI or loads a previously saved job. Set thickness is handled
automatically by the PSQ160. When the job is gathered in the PSQ160, each sheet
is flipped upside down by the infeed drum, therefore the job must be printed ‘first-to-
last, face up’. See
to
The PSQ160 is controlled by the printer and by a system of internal sensors.
3.1
Paper Enters the System
• When the print job starts, the printer sends a cycle-up signal to the PSQ160.
• Paper leaves the printer and enters the rotator module in the connecting bridge.
The paper is moved through the connecting bridge by belts into the gathering
area.
• Paper can be accepted from either ‘side-referenced’ or ‘centre-referenced’
printers. The connecting bridge translates the paper to ‘centre-referenced’ for the
PSQ160.
• When the page is in A4 portrait format, the paper can be rotated through 90° by
the turning-ball in the connecting bridge if necessary.
• A3 (17 x 11") and A4 (11 x 8½") landscape jobs move through the bridge without
rotation. The turning-ball is not in the paper path. The conveyor drive belt is at a
small angle to the sidelay and drives the paper against the sidelay.
Figure 5. A3 (11 x 17") paper moves straight through the connecting bridge
• A4 (8½ x 11") portrait jobs are rotated around the turning-ball. The paper is
driven against the sidelay by the angled, bridge drive-belt. The sidelay makes
sure the paper aligns to the centre reference line of the bridge.
