Tape Machine Feeds Short Tape Strips-
1. Erratic Short Lengths
2. Consistent Length, But Short
If you find that your machine is feeding short tape lengths, for example, the 18" key does not dispense the full 18" you first should determine whether the short strips are consistent. For example, is the 18" key always dispensing 17". Or, are the short lengths erratic. For example, the 18" key might dispense 17" or 14" or 15" etc.
1. Erratic Short Lengths
The most common cause is a worn Upper Feed Wheel (555- PW77X) or incorrect adjustment on the Lower Feed Wheel (555-E626XXX).
To Replace Upper Feed Wheel: See Figure 1 Below
Tools Required: 3/32" Allen Wrench / Phillips Screw Driver / Hammer / Small Punch
*Replace Feed Wheel If Surface Of Wheel Is Smooth
1. Remove both the Key Drum and Motor & Chain Cover
The Key Drum has a screw at each corner, plus one screw for
the Access Hole Cover (remove total 5 screws) The Motor Cover has 3 screws.
2. Remove water bottle & tank.
3. Loosen the 2 set screws on the Upper Feed Wheel, 1 set screw on Feed Wheel
Shaft Sprocket This sprocket holds the motor
chain Loosen 1 set screw on sprocket.
4. With the hammer & punch drive the groov pin out of gear -500PGear (Ref EA47)
5. Remove Chain Sprocket
6. Very gently, tap the Upper Feed Wheel shaft from left to right (facing front
of machine). Tap the shaft using the punch through gear -500PGear (Ref EA47). This gear
should now be on the end of the punch.
7. Slide the shaft out until the spacer washer & collar come off. Then slide it
slightly further until you can slide the old feed wheel off.
8. Slide the new Feed Wheel on. Slide the collar & spacer washer on next. Push
the shaft back through the right frame and clutch plate assy. Slide gear
500PGear back on end of shaft. Align hole in gear with hole in shaft and
drive groov pin -500GPIN ( Ref EA51) back into gear & shaft. Replace Chain Sprocket.
9. Tighten set screw on Chain Sprocket. Note that the Upper Feed Wheel Shaft
has a flat spot where the Chain Sprocket goes on. Make sure set screw is
tightened onto this flat surface.
10. Tighten collar -500CollarXX (Ref K37 X). HINT: Push the collar over against the spacer
washer & frame. We found that you should tighten the collar down but leave
about 1/32" gap between the collar and frame. The shaft should have just a
slight left-to-right movement.
11. Finally, align the Upper Feed Wheel so it is centered over the Lower Feed
Wheel. Tighten both set screws on the Upper Feed Wheel
Before re-installing covers: Are set screws on Chain Sprocket/Feed Wheel/Collar tight ? Is groov pin through pinion gear and Upper Feed Wheel Shaft?
If the Upper Feed Wheel appears to be in good shape, that is, it has grooves in the surface, but the machine is still feeding erratic short lengths, you need to adjust the lower feed wheel.
SERVICE FIGURE 1 - upper feed wheel parts
To Adjust Lower Feed Wheel - See Service Figure 2 Below
Tools Required: 3/32" Allen Wrench - Long (or T) Handle
1. Remove tape from tape basket.
2. Against the back wall (or Vertical Tie Plate) you'll see a small circular cut-out.
Look through this cut-out. You'll see the head of a 3/32" set screw. This screw
adjusts the height of the Lower Feed Wheel -600LFWXX (Ref E828XX).
3. Insert the Allen Wrench into the set screw. To raise Lower Feed Wheel
so it makes better contact with the Upper Feed Wheel, turn the Allen
Wrench clockwise.
4. CAUTION: Turn the Allen Wrench no more then 1 full turn and test the
tape feed. Raising the Lower Feed Wheel more then required creates
wear and can cause tape jams!
5. If the set screw appears loose (easy to turn) you can remove the screw
and put some LockTite or similar substance on it to keep it from backing out.
Can You Raise The Lower Feed Wheel Too High ?
Yes. If you do, you will notice that the tape is bent over Facing the front of the machine, the tape will have a slight bend on the left side.
Why Does This Happen?
As you raise the Lower Feed Wheel you decrease the travel height of the Upper Shear. If you notice that the tape is bending over and the tape is still slipping, the Lower Feed Wheel Assy 600LFWXX (Ref E626XX) should be replaced. Contact us. You might want to send it in for service. The frames have to be removed to replace the Lower Feed Wheel Assy. For more information on our service, click here.

2. Consistent Short Lengths -
see Service Figures 3 & 4 Below
Consistent short lengths are usually caused by incorrect adjustment of the Bumper Plate Part 555-EA3BX on 555 S Models or 555-EL3 on 555 L Models.
The adjustment is fairly simple.
ON "S" Model- Service Figure 3
1. Remove the Key Drum & Access Hole Cover (total 5 screws)
2.Loosen Cap Screw with LN-26 Hex Screw Driver. Move the Bumper
Plate in a clockwise direction to shorten tape lengths, For example, if the 12"
key is dispensing 11", this adjustment will correct this problem. It adds the
same amount to all key switches.
ON " L" Models - See Service Figure 4
1. Remove Key Drum & Access Hole Cover (total 5 screws)
2. Loosen Cap Screw Move the Bumper Plate (o Bumper Cup Arm
counter clockwise to lengthen tape lengths. For example, if the
12" key is dispensing 11" this will correct that problem.
Figure 3 & 4 adjustments may take several tries to get the exact length you want.
