It detects paper less than 203 x 280 mm (8 x 11 inches). Refer to
Figure 23 .
• Inserter paper width sensor 1, Q12-081 - The detector incorporates two width sensors.
Width sensor 1 is a flag sensor, actuated by the paper width guide position. The sensor
changes state at 285 mm, (11 1/4 inches) and 210 mm, (8 1/4 inches) paper widths. Refer
to
Figure 23 .
• Inserter paper width sensor 2, Q12-169. Width sensor 2 - A flag sensor, actuated by the
paper width guide position. The sensor changes state at 273 mm, (10 3/4) inches paper
width. Refer to

• Inserter jam cover interlock, S12-179. A micro switch, located behind the top inside cover.
This switch is wired in series with the inserter top cover interlock, to 24V to the
inserter. When both interlocks are closed, the +24V LED on the Inserter PWB is lit. Refer
to
Figure 24 .
• Inserter top cover interlock, S12-178. A micro switch, located behind the front cover. This
switch is wired in series with the inserter left hand door interlock, to 24V to the
inserter. When both interlocks are closed, the +24V LED on the Inserter PWB is lit. Refer

Booklet Maker Module
The booklet maker module receives, compiles, staples, folds and delivers finished booklets to
bin 2. Booklets can be up to 15 sheets, including a cover.
Compiling and Tamping
When a booklet maker job is requested, but prior to the first sheet arriving at the booklet maker,
the BM backstop motor, MOT 12-255 is energized to move the backstop assembly to a preset
receiving position based on the paper size value provided by the media path driver PWB. The
positioning of the backstop is measured in stepper motor pulses from the BM backstop guide
home sensor, Q12-204.
The booklet maker module receives sheets from the lower diverter gate and through the BM
entry roll nips. As each sheet is fed through the entry nip, it is driven downwards until it rests
against the backstop.
