TROUBLESHOOTING (Registration)
Normally, at average speeds, the Applicator will hold registration to within plus or
minus 1/32nd inch.
Variations of more than those limits are normally caused by:
Problem 1:
Label web binding.
Solution:
Check Web Guides (Drawing L60-I-60D #09 & #10) and Unwind Assembly
(Drawing UWA-13R-I-00), for proper clearance. Is peeler tape worn? (Drawing
L60-I-30D #29)
Problem 2:
Drive Roll glazed (Drawing L60-I-00D #06) and slippery or covered with labels or
glue.
Solution:
Clean with mineral spirits, lacquer thinner, alcohol, or other solvent.
Problem 3:
Drive Roll not parallel to Lower Idler Roller (Drawing L60-I-00D #06 & L60-I-10D
#05).
Solution:
Turn motor switch “off” and remove label web from Drive Roll and Idler Roller. Push
the Drive Roll away from the idler Roller and place two narrow strips of paper
between the Drive Roll and Idler Roller at each end of the drive roll. Release the
Drive Roll. The two strips, now trapped between the rolls, should have the same
“drag” when the strips are pulled in opposite directions. If not, adjustment is made
by loosening two bolts on the outside back of the machine, at the opposite end of
the Drive Roll Shaft and moving forward and back as required.
