Tri-Folder
When the job does not require a tri-fold, the tri-folder becomes a straight-through paper path
from the booklet maker to the output tray. When a tri-fold is requested, the tri-folder clutch,
diverter solenoid, and for C-folds only, the assist gate solenoid are brought into use.
The tri-folder does not require a dedicated drive motor, but takes its motive power using a
toothed belt and drive coupler, from the crease roll motor in the booklet maker. The drive cou-
pler engages when the booklet maker is pushed into the home position. The belt turns as each
sheet is folded and stops as each sheet leaves the tri-folder.
When the tri-folder is not installed, a shorting link fitted to PJ553 in the booklet maker PWB,
simulates the tri-folder interlocks, to feed +24V to the booklet maker PWB.
The tri-folder works in conjunction with the booklet maker, to produce ‘C’ or ‘Z’ folds. The book-
let maker makes the first fold, and passes the sheet to the tri-folder to make the second fold.
One sheet at a time is folded, and the tri-folder can fold 60-120gsm, (15-30lb) sheets.
Figure 27
shows how the C-folds and the Z-folds are formed. The difference lies in where the
first fold is made in the sheet, by the booklet maker. For a C-fold, the backstop is raised to pro-
duce a fold near the leading edge of the sheet. For a Z-fold, the backstop is lowered to produce
a fold near the trailing edge of the sheet, effectively inverting the sheet.

The active components of the tri-folder are:
•
Tri-folder entry sensor, Q12-164 - A flag sensor, located in the input paper guide. This
sensor detects the sheet entering the tri-folder from the booklet maker. Refer to
Figure 28
.
•
Crease roll clutch, CL12-269 - The clutch is located at the rear of the tri-folder, and actu-
ates to drive the tri-folder crease rolls via a toothed belt. Refer to
Figure 28
.
•
Tri-folder diverter solenoid, SOL12-267 - The solenoid is located at the rear of the tri-
folder, and diverts single, tri-fold job sheets into the folder mechanism. It is actuated
immediately after the drive belt from the BM starts to turn, and de-actuates as each sheet
leaves the tri-folder. Refer to
Figure 28
.
•
Tri-folder assist gate sensor, Q12-165 - A flag sensor, located in the roller assembly, and
is mounted on the adjustable backstop plate. This sensor detects the sheet entering the
roller assembly to be folded. Refer to
Figure 28
