Almost exclusively, slow tape feed is due to worn motor brushes – MOTORBRUSHKIT (Ref. ND105BXK) or a defective motor – MOTORASSY(Ref. ND105X).
Check Tape Feed First!
You should first check to make sure the tape is not binding. Check inside the tape basket to make sure the tape guides are not “pinching” the tape roll. Check the upper tape plate. Does it slide out easily? It should. Over time, they can get bent and bind down on the tape. If you notice that the upper tape plate is bent, replace it. If the tape is not binding, next check the motor brushes.
A. Replacing Motor Brushes
Tip: Whenever we remove or replace motor brushes, we stand the machine upright and gently tap the moto with a pair of pliers to dislodge the carbon that has worn off of the brushes. Place a paper towel on the work surface to collect the carbon dust.
- Unplug the machine.
- Remove water tank and bottle.
- Remove motor and chain cover (a total of three screws).
- Toward the back of the motor, on the top and bottom of the motor are two black plastic screw caps. Using a slotted screwdriver, remove the caps.
- You’ll see the top of the motor brushes – a small copper or steel circular plate.
- The motor brushes are spring loaded and should “pop up” when the black plastic cap is removed. If they don’t, the tip of a paper clip can be used to pull the motor brush up.
- If the carbon is less than 0.25″, replace both brushes.
B. Replacing Defective Motor
- Unplug the machine.
- Remove the motor and chain cover (a total of three screws).
- The motor bracket has three bolts. Remove the nuts, but leave the bolts on the frame.
- Remove the green ground wire on the motor.
- Remove the motor chain.
- Remove both electrical caps and remove old motor wires.
- Mount the chain on the new motor.
- Mount the motor on the three bolts on the frame.
- Replace and tighten the bolts.
- Replace the green ground wire.
- Connect the motor wires and replace the electrical caps.
Checking motor chain tension:
The motor chain should not be pulled too tight. The chain should be slightly loose. To adjust:
- Look on the opposite side of the motor. You’ll see two bolts (555-E638) on the inside of the motor bracket (they will be facing the frame).
- Loosen the bolts and mote the motor back or forward to adjust chain tension.
