Functional Test
Before attempting to process forms with the 3800, perform the following functional test. Make
sure the power switch is in the off position and set the depth control indicator (7) to “Open” (at the
“Open” position, the upper cutter shaft should be at the highest point). To adjust the depth
control, loosen the depth control locking knob (6). Turn the depth control knob counterclockwise
until the knob indicator aligns with the zero on the depth control scale. Retighten the depth
control locking knob.
Open the safety cover (13) and inspect the accessories on th e upper shaft. Make sure none of the
accessories are contacting the backup hubs on the lower shaft. Close the safety cover (13). Plug
in the machine and turn the speed control (7) clockwise until the machine just begins to run.
Increase the feed speed by continuing to turn the knob clockwise. Open the safety cove (13). The
machine should stop. Turn the speed control (7) to the off position. The 3800 is now ready for
operation setups for perforating, scoring, or slitting.
Setup and Operation
Set of the 3800 is based on paper side, paper weight and operation to be performed. Scoring,
perforating and slitting operations may be done individually or simultaneously except the
perforating and score combination. The operator is required to position each component and
adjust for paper stock and operation depth. The speed of the machine is variable and must be
adjusted to suit the paper stock and operation being performed. This machine incorporates a dual
bottom feed system that provides positive feed. Paper stock can be added without interrupting
operation.
Note – Always test a new setup by hand operation prior to applying the power.
This will prevent damage to the perforator components.
I.
Feed Table Setup (Figure 1)
Loosen the four paper guide locking knobs and position the guides (2) slightly wider than the
paper stock to be processed. Place a piece of paper stock on the feed table (1) with the center of
the paper aligned approximately with the orange feed tire. Next, position the paper guides (2) s o
that each guide touches the corresponding side of the paper. Tighten the four locking knobs.
Note
– Paper guide position may be fine tuned by using the fine tuning adjustment knob.
The
guides can be moved independently or at the same time. Loosen the locking knobs on the guide(s)
to be moved. Lock both knobs if the guide does not need to be moved.
II.
Retarder
Place one sheet of the paper to be run between the retarder and feed roller. Hold the sheet by
the tail end and adjust the retard until you feel a slight drag on the paper. The retarder roller is
raised and lowered via the knob (8) on top of the retarded housing. Utilizing the hand wheel
(5), manually operate (cycle) the machine for one complete revolution of the feed roller. If
you do not feel an even pull throughout the entire cycle, readjust the retarder.
Note – Apply
only enough pressure on the retarder for positive feeding. Too much pressure will cause
excessive wear of the feed roller and retarder.
III.
Slot Perforator Setup (Figure 1 and 3)
Mark a sheet of the paper to be processed at the leading edge of the position(s) of the desired
perforation(s). Place the sheet onto the feed table (1) with the marked edge closest to the
infeed roller. Adjust the paper guides (2) so the sheet slides freely down between the guides
without excessive side play. Check the feed system for proper adjustment.
