Paper Feed Adjustment and Set Up
The paper retarder mechanism is situated under the main feed table. This mechanism is
adjustable to allow the main feed roller to automatically feed single sheets of paper. The
correct adjustment of this retarder is vital to the paper folder machine performance.
The retarder roller is adjusted by the use of a thumb screw situated underneath the main
feed table.
a)
With the power off take a sheet of paper and slide between the retarder roller and
main red feed roller.
b)
Adjust the retarder roller upwards until a slight drag can be felt, when you try to
remove the sheet. This is the correct set up for single sheet automatic feeding

Loading paper into the feed table
Correct loading of the paper into the paper folder is essential for trouble free folding.
Friction fed paper folders like the DT850 requires you to load the paper in a shingled
batch. Instead of the stack of paper being loaded as a square block into the folder, the
stack should be shingled or fanned back so as each end of the stack is now angled or
shingled.
Once this is achieved load the stack of paper into the feed table with the top sheet
positioned into the main (red) feed roller. The folder is now ready to operate
Too much space between the rollers will cause more than one sheet to be fed and can
cause possible jamming. Too tight adjustment will cause paper not to feed and excessive
wear on the feed rollers.
