Problem: Tape tail does not stick down properly.
The end of the tape on the back side of the case as it leaves the machine has not adhered well to the box.
Check these conditions:
•
Tape tension. Tension should be is smooth and not too tight. "Snap back" will cause tape tail to
recoil and not stick well on the back of the case.
•
Tape head roller contact. Tape head contact or wipe-down rollers should make good contact with
the box. Adjust roller spring tension, if necessary.
Problem: Tape is off-center.
The line of tape is not centered over the gap between flaps on the top or bottom of the box. Look for the
following conditions:
•
Tape roll position. Check that the tape roll is fully pushed on to spool.
•
Tape head straight. Check that the tape head sits straight in its bracket and is not tilted to either
side.
•
Obstructions. Look for obstructions that could be pushing the tape off center.
Problem: Tape Falls Forward on Bottom Head.
The beginning end of the tape must stand vertically in front of the tape head front roller in order to
contact the leading end of the next case. A bow made across the tape by the tape head guides help to
stiffen it and a static electric charge on the tape head rollers attract the tape and help to keep it in place. If
the bottom tape will not stand vertically, examine the following factors:
•
Contamination. Tape may be wound around the roller or other dirt on the roller.
•
No static charge. Dust roller surfaces with talcum powder to the increase static charge on the roller.
•
Tape head guides. Check that the tape holder or finger is set correctly, see tape head manual.
•
Ambient conditions. A strong breeze in the vicinity of the tape sealer can cause the tape to blow
down. High temperature or humidity may affect tape characteristics.
•
Type of tape. Some brands and types of tape have more 'body' than others and a change of tape may
be needed, particularly in difficult ambient conditions.
