in the direction of the paper travel.
Re-tighten the nut to lock the retarder in this position.
Note: The retarder roller should always be locked in a stationary position.
5.2.6 Paper has a curl in it
Paper will sometimes develop a curl that makes automatic feeding difficult. This is especially
common in paper just printed from a laser jet printer. Stacking it and placing a large heavy object
such as a large book on it for a couple hours can straighten paper. Another option is to place the
paper on the 1501 feed table with the curl down.
5.2.7 Retarder pressure needs adjustment
Retarder pressure is pre-set at the factory and should require no further adjustment throughout the
life of the folder. However, if feeding problems continue after following the above steps, the
retarder pressure can be adjusted by turning the retarder pressure knob clockwise to increase
pressure or counterclockwise to decrease pressure. The normal tendency is to place too much
pressure on the retarder resulting in feed wheel damage. Call Martin Yale customer service at
(260)-563-0641 if further assistance is needed.
5.3 Crooked Folds
5.3.1 Excessive paper guide side play
Readjust the paper guides to eliminate excessive side play between guides and paper edges, per
section 2.3 of these instructions.
5.3.2 Paper guides not aligned properly
Align paper guides per section 2.3 of these instructions. Be sure paper stack is square and
centered in the feed tray.
5.3.3 Paper stops not aligned properly
Align paper stops per section 2.4 of this manual. To rule out crooked feeding, test with single
sheet of paper in single sheet operation, bypassing the feed tray completely.
5.4 Ink smudges on paper
5.4.1 Ink not dry
Allow additional ink drying time before folding. Some inks do not dry, they only set (dry to the
touch). Because of the physical nature of friction feeding, you may notice a mark on the leading
edge of the paper.
5.4.2 Excessive toner on photocopied stock
Check copy machine
5.5 Wrinkled paper
5.5.1 Feed table paper guides misaligned
Align the paper guides perpendicular to the folding rollers until the paper feeds straight into the
folder. Review section 2.3.
5.5.2 Feed table paper guides too tight
Set guides so that sheets slide freely down between the guides without excessive side play.
Review section 2.3.
5.5.3 Dirty
Rollers
Dirty rollers are often the cause of wrinkled paper. Clean rollers as described in section 4.1.
