Tape Feed Problems:
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 E626XX
d.) Worn feed wheel PW77CX2) Long lengths or constant feed
a.) Oil on measuring wheel EA18BXX, EL4AXX
b.) Worn clutch roller EA52AXX
c.) Incorrectly adjusted clutch roller EA52AXX
d.) Worn trip roller (reset roller for key switches) E538AXX
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 mechanism3)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 FM11AX6) 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
Electrical Problems:
1) Machine doesn't operate but pilot light and heater work
a.) Improperly adjusted safety switch FF112 so that switch
doesn't close when measuring wheel EA18BXX or EL4AXX returns to rest.
b.) Defective safety switch FF112 or assembly2) 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 ST1133) 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 connection4) 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 ND105X5) Solenoid doesn't operate
a.) Poor connection at wire nuts E634, E634A under motor cover
b.) Defective solenoid E550X6) One key switch will not operate machine (all others do)
Defective key switch E501LX
7) Random switch doesn't operate
Defective random switch ST114
Cutting Problems:
1) Shear Problems
a.) Shear blades have accumulated asphalt or non- asphaltic gum. Clean with suitable solvent and keep blade oiler fully oiled.
b.) Check stationary blade FM21X for correct lateral adjustment
c.) Blades dull FM20BXK
d.) Cutter spring E585C needs replacing
e.) Shear pivot holes cutter yoke E584RAX worn elongated
f.) Solenoid E550X has to much up and down motion on mounting plate.
Miscellaneous Problems:
1) Solenoid E550X buzzes.
a.) Solenoid mounting too tight. (not free to align itself)
b.) Solenoid mounting screws not evenly tightened.
(plunger of solenoid not evenly seated)
c.) Rust in and around plunger of solenoid.
d.) Solenoid sponge pad E599 worn or deteriorated. (E599 discontinued call for replacement option).2) Tape roll jumps out when feeding.
a.) Core from previous roll of tape in machine.
b.) Bottom roller FM59X in basket missing or broken.
