Principles of Operation
• Tri-folder assist gate solenoid, SOL12-268 - The solenoid is located at the rear of the tri-
folder. The assist gate solenoid is only actuated during C-folds, to assist the first folded
flap into the crease rolls. It actuates as the sheet enters the crease rolls and ensures that
the trailing edge of the first fold stays inside the crease of the second fold. Refer to
Figure
28 .

• Folder exit sensor, Q12-166 - A flag sensor, located in the exit paper guide. This sensor
detects the sheets as they leave the tri-folder. Refer to
Figure 29 .

• Tri-folder top cover interlock switch - A single-pole micro switch, located at the front of the
tri-folder. This switch is connected in series with the front door interlock switch, S12-209.
When both switches are made, the +24V supply is fed to the tri-folder PWB and the BM
PWB. The BM PWB has +24V LED indication, as described in the Power / Interlocks sec-
tion of this document. Refer to
Figure 30 .
• Top cover interlock sensor, Q12-210 - A flag sensor, located towards the rear of the tri-
folder top cover. This sensor detects whether the top cover is open or closed. Refer to
Figure 30 .
• Front door interlock switch, S12-209 - A double-pole switch, located behind the top of the
tri-folder front door. One pole of this switch is connected in series with the TF top cover
interlock switch. When both switches are made, the +24V supply is fed to the tri-folder
PWB and the BM PWB. The second pole of this switch detects whether the tri-folder front
door is open or closed. Refer to
Figure 30 .
