Page 12: Important Points
B889 - Fan Fold Unit Important Points - 1/2 The Fan Fold Unit can handle plain paper only. Do not feed translucent paper or OHP transparencies through the Fan Fold Unit. If the humidity at the work site is extremely high, turn on the heater switch of the Fan Fold Unit. - Page 13 B889 - Fan Fold Unit Important Points - 2/2 When a fan fold is adjusted, the last surface will be shorter than the others, because the lengths of the others have been increased. For example, if fan folding is increased by +0.05 inches for a job where three folds are done to create four surfaces, +0.5 will be added to the first 3 surfaces but the last surface...

- Page 25 B889 - Fan Fold Unit Folding - 5/8 Fan Fold Plate Fan Fold HP Sensor (F) Plate (F) Fan Fold Plate Motor (F) After the leading edge is fed the correct distance, fan fold plate motor (F) reverses and the fan fold plate (F) lifts. It stops when the HP sensor detects the edge of the plate.
- Page 26 B889 - Fan Fold Unit Folding - 6/8 Fan Fold Plate (R) Fan Fold Plate Motor (R) Fan fold plate motor (R) turns on. This lowers fan fold plate (R). The plate pushes the paper between the fan fold rollers (L). This makes the second fold.
- Page 27 B889 - Fan Fold Unit Folding - 7/8 The second fold is made. The process continues as described earlier. Slide 27 The cycle repeats until all the folds are completed: The fold plate motors alternate the raising and lowering of the fold plates to push the paper into the front and back fan fold rollers that form the folds.
- Page 28 B889 - Fan Fold Unit Folding - 8/8 Fan Folder Entrance Sensor Fan Fold Rollers (R) When the trailing edge of the paper passes the fan folder entrance sensor, there are no more folds to make. The fan fold rollers feed the folded output out of the Fan Fold Unit.
