1) Feeds erratic short strips (feed wheels not gripping tape securely)
a.) Incorrect adjustment of set screw on cutter yoke assembly
- E584RAXX
b.) Elongated holes in frame E500LXX or E500RXX for cutter yoke pivot shaft FM32
c.) Worn idler assembly - E626XXX
d.) Worn feed wheel - PW77CX
2) Long lengths or constant feed
a.) Oil on measuring wheel - FF50XXX
b.) Worn clutch roller - EA52AXX
c.) Incorrectly adjusted clutch roller - EA52AXX
d.) Broken reset lever on measuring wheel - FF160
e.) Check relay - FF127R
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 - E550
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 Heater Assy. - TH55PXXX
e.) Insufficient space between heater pivot rod E580SA and lower tape plate - FM11ARX
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
8) Feeds one strip on top of other
Misadjusted or bent finger FF119A
9) Feeds erratic short lengths
Check relay FF127R
10) Random lengths in manual and random mode, okay in robot mode
Check relay FF127R
NOTE: The best way to check a questionable relay is to temporarily replace
it with a known good one.
1) Machine doesn't operate but pilot light and heater work
a.) Improper switch push rod assembly and finger adjustment
b.) Defective cut out switch FF112
c.) Check finger FF119A and it's adjustment.
switch FF112 should turn on when finger drops through hole
in lower tape plate
d.) Short strip of tape remaining in machine under finger not allowing it to drop into
position.
2) Machine doesn't operate, pilot light doesn't light
a.) Power cord not plugged in
b.) Break in power cord PCPG1AX
c.) Main power switch defective ST113
3) Machine doesn't operate: pilot lights - heater doesn't work
a.) Harness plug from key drum to machine not plugged in or connections
are poor
b.) Wire nuts E634 and E634A connecting motor ND105X and solenoid E550X inside motor cover
are not making good connection
4) Motor doesn't operate
a.) Poor connection at wire nuts E634 and E634A under motor cover
b.) Worn motor brushes - ND105BXK
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
