Page 5: Tape Jams

A common problem that is usually easy to correct. What are the possible causes of tape jams?

  • Worn / dirty moistening brushes
  • Lower tape plate out of adjustment
  • Debris in and around shears (small enough that it may not be clearly visible)
  • Glue build up under top heater
  • Bent upper tape plate

A. Cleaning / Replacing Moistening Brushes

Moistening brushes slightly lift the top heater up. This provides cleaerance so that the tape can feed under the top heater and over the brushes. If the brushes are too worn, the top heater rests on the lower tape plate and the tape will jam. If the brushes are that worn, replace them.

  1. Unplug the machine.
  2. Remove the water tank and bottle.
  3. Inspect moistening brushes. Is there a glue build up on the tips? Before replacing them, try cleaning them in warm soapy water. Let them soak over the weekend.
  4. By cleaning the moistening brushes, they can “stand up” better and support the top heater. This can eliminate tape jams (and improve moistening).

B. Lower Tape Plate Out of Adjustment

  1. Unplug the machine.
  2. The lower tape plate comes out under the top heater. Note that the top heater pivots on a rod.
  3. Lift up the top heater.
  4. Using a slotted screw driver, insert the tip between the lower tape plate and lower heater plate. Insert the screwdriver near each of the two small brass rollers. Gently twist the screwdriver to create a gap between the lower tape plate and lower heater plate. This allows the tape to flow out over the lower tape plate and over the lower heater plate.

C. Debris In and Around Shears

  1. Unplug the machine.
  2. Remove the water tank and bottle.
  3. Lift up the top heater.
  4. Carefully check for any pieces of tape.
  5. Push up on the yoke assembly. This is a gray metal shelf located just inside the front of the machine. It holds the upper shear. Carefully look for any debris, pieces of cut tape, glue, etc. Remove all debris in and around shear area.

D. Glue Build Up Under Top Heater

  1. Unplug the machine
  2. Lift up the top heater
  3. Look for any dry glue that has built up on the lower heater plate.
  4. Carefully scrape the glue off with a razor or knife. Be careful not to cut the heater cord!

E. Bent Upper Tape Plate

Surprisingly, a bent upper tape plate can cause tape jams. Over time, the upper tape plate can call and bend. To test if it is bent, simply remove it. It should slide out easily. If it doesn’t, or if it is bent, replace it. A bent tape plate restricts the tape feed and can cause jamming.
