1) Feeds erratic short strips (feed wheels not gripping tape securely)
a.) Incorrect adjustment of set screw on cutter yoke assembly
E555-049-01
b.) Worn idler assembly E555-053-00
d.) Worn feed wheel PW77CX
2) Long delays between repeated lengths
a.) Check motor chain adjustment
b.) Check circuit board
3)Tape feeds slowly
a.) Poor motor brush contact with commutator
b.) Worn motor brushes
c.) Defective motor ND105X
d.) Tape is binding
4) No Tape Feed
a.) Top cover not closed
b.) Missing magnet in top cover
c.) Magnet not coming into contact with Magnetic Proximity Switch
d.) Defective or disconnected Magnetic Proximity Switch
e.) Motor not operating ND105X
f.) Solenoid not operating E550X
g.) Blade does not go down, check cutter spring
h.) Cutter yoke far out of adjustment - feed wheel PW77CX
not gripping tape.
5) Tape Jams

b.) Tape is being pinched by pressure plate due to worn moistening brushes
c.) Upper tape plate missing or not in correct position
d.) Moistening brushes in backwards or not set in tank properly.
6) Left hand corner of tape folded over
Lower feed wheel adjustment too tight causing the feed
wheels to contact and feed tape before the blades gets out of the way.
7) On the BP555eSA and BP555eLA a beep is heard after each
strip
a.) Check tape sensor mounted on the back of the heater for
broken wires
b.) Check connection of tape sensor on circuit board
1) Machine doesn't operate
a.) Check to make sure top cover is closed
b.) Make sure machine is plugged in
b.) Check main fuse
2) Heater doesn't work
a.) Check adjustment setting on top
b.) Check plug to main circuit board
c.) Check circuit board and/or heater
3) Some or all key selectors do not function
a.) Inspect ribbon cables for damage
b.) Check connection of cables to circuit board
4) Motor doesn't operate
a.) Poor connection at wire nuts E634 and E634A under motor cover
b.) Worn motor brushes
c.) Brushes not contacting commutator
d.) Defective motor ND105X
5) Solenoid doesn't operate
a.) Poor connection at wire nuts E634, E634A under motor cover
b.) Defective solenoid E550X
6) Motor runs, tape is not dispensed
Check solenoid clevis pin, replace with bolt.
7) Blade in up position, or does not reset
Check cutter yoke spring E585C
1) Solenoid E550X buzzes.
