e.) Incorrect adjustment of trip roller E538AXX
f.) Defective key switch E501LX, doesn't turn off
g.)Defective random key switch ST114
h.) Safety switch FF112 defective or not being actuated by mechanism
3)Tape feeds slowly
a.) Poor motor brush contact with commutator
b.) Worn motor brushes
c.) Defective motor ND105X
d.) Tape is binding on sides (especially if CodeTaper is attached)
4) No Tape Feed
a.) Motor not operating ND105X
b.) Solenoid not operating E550X
c.) Neither motor or solenoid operating
d.) Cutter yoke far out of adjustment - feed wheel PW77CX
not gripping tape.
5) Tape Jams
a.) Shear blade FM20BXK doesn't lift up before tape feeds.
b.) Tape is being pinched by pressure plate due to worn moistening brushes
c.) Upper tape plate FM12EL missing or not in correct position
d.) Reduce weight on pressure plate heater assembly TH55PXXX
e.) Insufficient space between heater pivot rod E580SA and lower tape plate FM11AX
6) Left hand corner of tape folded over
Shear FM20BXK too low. (check rocker set screw adjustment to raise shear)
7) Strips not correct length, but consistent (lengths inaccurate up to
1")
See length adjustment instructions
1) Machine doesn't operate but pilot light and heater work
