REGISTER OPERATION
Use the fluted knob (Figure 19-1) to slide the side guide
(19-2) with the marble holder (19-3) to the required location
1/16" away from the pile stack.
Move the sheet support (19-4) to the right hand side of
the sheet.
Place the steel and/or plastic marbles into the marble
holder (19-3). It is recommended to have at least two steel
marbles in the first four to six positions closest to the pile
feeder end.
The succeeding positions can be filled with steel or
plastic marbles depending on the stiffness of the paper. For
registering oblong sheets it is recommended to have at least
50% steel and 50% plastic marbles alternating in the marble
holder.
Clip-on sheet hold-downs (19-5) placed across the
register table prevent the sheets from rising. The hold-down
with the angle-formed end is to be placed in front of the
vacuum wheel.
The fluted knob (19-6) provides microadjust-ment of
the side guide (19-2). Knurled knobs (19-7) provide bias
adjustment for the side guide for adjusting sheets that are
not square or for other unusual conditions.
The double sheet control (Figure 20) is adjusted to the
thickness of the paper being fed by pulling up the lever (20-
1) and inserting two paper strips (20-2) of the sheets to be
folded in the clip at the back of the lever.
The feeler segment remains inoperative when a single
sheet is passing through. When double sheets are being fed
through, the feeler segment is pulled against a microswitch
and the double sheet is stopped. Sheet feeding is stopped
and the message "2 sheet" appears on the counter readout.
The message remains until the double sheet is removed.
Raise the lever (20-1) to remove the double sheet.

1.0 DOUBLE SHEET DETECTOR
The double sheet detector consists of a scanner element,
microswitch and a free-wheel roller.
If the setting for paper thickness is exceeded, the
scanner element trips the microswitch, closing the magnetic
valve for the suction cycle so that sheet transfer is stopped
instantaneously. While the double sheet is stopped, the
sheets that are in the machine continue to be folded.
The double sheet stop must be set so that the scanner
probe remains untouched when a single sheet of paper
passes through. When two or more sheets are detected, it
must trigger the stop mechanism. (See Figure 21)
