FOLD PLATE ADJUSTMENT
Half Fold Defl ector
To adjust fold plates to desired fold and length of paper, fi rst loosen the two thumbscrews on each of the two fold plates. Second, align the center bar so the marks on each side of the fold plates match up.
Letter, accordion and half folds are clearly marked on each fold plate with blue lines. An adjustment can be made by loosening the thumbscrew and slightly moving the center bar up or down. Tighten the thumbscrews before operation.
For a “half” fold or “V” fold you must remove the lower fold plate and rotate it 180 degrees and reinsert the fold plate with the half fold defl ector leading.
NOTE: Remember to tighten the thumbscrews and replace the fold plates before operating.
OPERATION
- To load paper, press lever to tilt down Infeed Tray, and slide paper under infeed wheel. Release lever.
- Adjust the Paper Guides so the center of the sheet is aligned and paper can slide freely between the guides without excessive play. To adjust, grip the guides at the top and bottom where they are held in place on the cross shaft and slide into position. NOTE: Improper setting of the paper guides may cause inconsistent folding or skewed folds.
- Press the green Start button. Paper is automatically fed from the pile, folded and deposited into the Catch Tray. To avoid malfunction, periodically remove folded paper from the Catch Tray.
- To stop operation prior to the last sheet on the Infeed Tray, press the red Stop button.
- After the last sheet is folded, the machine turns off automatically.
