The 2620 Power Feeder provides double free steady forms to the 2612
Folder/Sealer. Attach the stacker extension using the to knobs provided.
Load the forms and adjust the width using the right tray guide on top of your
2620 Power Feeder.
The double detector is set at the factory for most forms. When setting up
your 2620 check the double detector to the form. Take one sheet of the form and
fold it in half and put it through the rollers of the double detector. Adjust the double detector know at the top of
the feeder so the red light will come on when two forms go through at the same
time.
Then push the start button on top of the 2620 feeder. The two gray rollers
will touch the forms first, this will start the gray rollers to take the forms
forward to the rollers of the 2612 Folder/Sealer. The pick off height is set at
the factory, the knob will allow you to adjust the gray rollers. When the gray
rollers eventually wear out, the operator may easily replace them by removing
the two blue clips.
If a double occurs the red light should come on. If this should happen push
the top button and the stack will go down. Then pull the forms that caused the
jam from the feeder and restack them. Then push the top button and the 2620
Power Feeder should be working properly. Note: You don’t have to wait until
the stack reaches the bottom to restart the feeder.
MAINTENANCE
GENERAL
This section includes mechanical descriptions, technical adjustments, removal
and replacement, and troubleshooting.
CLEANING
Take a few minutes at the end of each day to wipe off accumulations of paper
dust. Cover your machine when not in use. These practices will keep your machine
clean and in tip-top operating condition.
ROLLERS
Keep rollers clean. Most feeding problems are the result of paper dust
accumulation on the feeder rollers. Rollers should be cleaned on a regular basis
to maintain optimum feeding performance.
Clean rollers weekly using water only, and a lint free cloth.
Check rollers periodically for wear. Worn rollers will be evident by
inability to control paper and inaccurate feeding. Never touch the gray surface
of the rollers with hands. This will put oil onto the rollers and cause them not
to function correctly.
To replace rollers you must first disconnect the power. After noticeable wear
on the rollers you may want to rotate them to even the wear. The roller to wear
down first will be the first pick off roller. The one-way bearings will only
permit the rollers to rotate one direction. Install the rollers with the bearing
side going away from the chain as when you removed it.
TECHNICAL ADJUSTMENTS
DOUBLE DETECTOR
The distance between the two rollers is the most critical. When replacing the
Double Detector Assembly, set the distance by doing the following. Loosen the
two screws on the Idler Roller Assembly, slip a piece of Xerox paper between the
rollers and the lower Idler Roller Assembly. So that it is pressing the paper to
the lower roller then tighten the two screws, make sure it is straight.
PICK OFF HEIGHT
The two main reasons of miss feeding are dirty rollers and pick off sensor
adjustment. The rollers can be cleaned with a damp cloth. Depending on form’s
condition, adjustment height will vary. Adjust the knob so that the sensor is in
the middle of the rectangular hole. If it is feeding intermittently, raise the
sensor. And if it is doubling, lower the sensor.
SIDE GUIDES
The side guide adjustment is to accommodate different form widths. To adjust
side guides loosen the thumbscrew and move accordingly. Make sure not to set the
side guides too tight against the forms. This may cause a misfeed.
REMOVAL AND REPLACEMENT PROCEDURE
GRAY ROLLERS REPLACEMENT
1. Unplug machine.
2. Remove the blue clips on the outside of the rollers.
3. Remove the gray rollers and replace with the new rollers. NOTE: Make sure
the bearing side of the roller is away from the chain as when you removed
them.
DRIVE LINK ASSEMBLY REPLACEMENT
1. Unplug machine.
2. Remove the gray rollers.
3. Remove e-clips and the cotter pin from the gear.
4. Slide the shaft through the oilite bearings and replace with new drive
link assembly.
GEAR REPLACEMENT
1. Unplug machine.
2. The bottom gear is held on with two set screws. Loosen the set screws with
an Allen wrench and slide the gear off.
3. The middle gear is held on with an e-clip. Remove the e-clip and using a
Phillips screwdriver loosen the screw holding the idler stud on. Slide the
gear off.
4. When replacing the gears make sure to align them horizontally by using the
idler stud and the bottom gear. There should be a small amount of backlash
between each gear. First adjust the middle gear and the top gear by moving the
idler stud. Next adjust the middle gear and the bottom gear by moving the
motor
MOTOR REPLACEMENT
1. Unplug machine.
2. Remove cover and unplug motor connector from pc board.
3. Loosen the two set screws on the motor gear. Using a Phillips screwdriver
loosen the two screws holding the motor in place. Remove the old motor and
replace with the new motor. You need to wire it the same way the old motor was.
DOUBLE DETECTOR ASSEMBLY REPLACEMENT
1. Unplug machine.
2. Disconnect the extension spring from the bracket.
3. Using an Allen wrench, remove the two screws holding the double detector.
4. Remove the sensor.
5. Using a Phillips screwdriver loosen the two screws holding the bracket on
and remove the double detector sensor assembly.
6. Replace the old detector assembly with the new detector assembly.
7. Set the gap between the two silver roller bearings, so that 1 sheet of
Xerox paper can go through with ease. Make sure rollers are not touching.
PC BOARD REPLACEMENT
1. Unplug machine.
2. Disconnect connectors from the pc board. Using a Phillips screwdriver
loosen the four screws holding the pc board on.
3. Replace with the new pc board and reconnect the connectors the same way
they were connected.
POWER SUPPLY REPLACEMENT
1. Unplug machine.
2. Using a Phillips screwdriver loosen the four screws holding the cover on.
Then remove the cover.
3. Using a Phillips screwdriver loosen the four screws and disconnect the
connectors, then remove the power supply.
4. Replace old power supply with new power supply. NOTE: Don’t forget to
reconnect ground wire to lower right screw of the power supply cover.
