Tape Not Cut Consistently
| Possible Causes | Solutions |
|---|---|
| Tape head position is set too high. Cutter Blade does not activate fully. | Ensure tape head side plates are within 1/16 to 1/8” of the case. |
| Cases rising UP between the conveyor belts. | Ensure tape head side plates are within 1/16 to 1/8” of the case.For bottom-only sealing, ensure the hold-down rollers (if equipped) are properly engaging. |
| Tape Tension: • Too strong causes tape debris buildup on blade. • Too weak prevents tape cut-off. | Adjust Tape Tension accordingly. See user manual. |
| Blade is dirty. | Clean the blade and apply a little silicone or oil to prevent adhesive buildup on the blade’s teeth. Never use a hard or metal object to clean the blade. |
| Blade dull or damaged. | Replace if dull, or if teeth are damaged. |
| Tape Cutter Spring tension is too weak. | Replace the spring if it is too weak.For instructions, see user manual. |
Tape Tail Falling: Bottom Tape Head
| Possible Causes | Solutions |
|---|---|
| Tape Profile and Tape Profile Angle not holding the tape upright. | Adjust the Tape Guide to increase the tape’s curvature and stiffness. Increase the Tape Profile Angle to support the tape more. See user manual. |
| Contact Rollers have poor static cling. | Dust contact rollers with baby (talcum) powder to increase static clinging of tape. |
| Environmental conditions. | Reduce or eliminate any strong breezes near the tape head.Address any high temperature or humidity conditions that may affect tape characteristics. |
| Tape suitability and type. | Use a suitable tape type for your application.We recommend using tape at least 1.7 mil in thickness. |
Tape Not Sticking to Case
| Possible Causes | Solutions |
|---|---|
| Under-filled Case, causing the flaps to sag inwards as the Rollers press and apply tape. | Reduce the Wipe Down Force spring tension. Ideally, have the case size fit the product. See user manual. |
| Overlapping flaps. If the outside (major) flaps overlap, this creates an uneven and poor taping surface. | Contact your corrugated case supplier to correct the defective cases.Release excessive pressure on sides of case. Release side guide or side belt pressure on sealer.Reduce the Wipe Down Force of the Wipe Down Roller. See user manual. |
| Contact Roller has poor contact with case. | Ensure the tape head and Wipe Down Rollers sufficiently contact the case and that the Main Spring tension is correct. See user manual. |
| Dust or dirt on the cases or in the air affecting adhesive effectiveness. | Prevent accumulation of dust on cases. |
| Temperature. Extremely hot or cold temperatures can adversely affect tape adhesion. | Use suitable tape for your operating environment. |
| Tape adhesive quality is poor. | Check the quality of tape adhesive. We recommend the Hot-Melt type of adhesive over Acrylic adhesives for most applications. |
Trailing Tape Tail Not Adhering
| Possible Causes | Solutions |
|---|---|
| Tape tension is too strong, causing tape to recoil when cut and not stick to the case. | Loosen tape tension accordingly. See user manual. |
| Wipe Down Roller pressure is too weak. | Be sure the Wipe Down Roller is actively pushing the tape down and that the spring is in good condition and set to the right tension. See user manual. |
| Tape Tail Length is too long. | Shorten the Tape Tail Length. See user manual. |
| Tape threading incorrect. | Ensure tape threading follows the guiding arrows on the tape head. See user manual. |
| Tape is off-center. | Ensure tape is pushed fully onto the Tape Roll Hub.Ensure tape head is mounted correctly. See user manual. |
| Contact Roller condition is poor. | Ensure contact rollers are clean and free from nicks or cuts. Clean with solvent if necessary. Replace contact rollers if necessary.See parts replacement guide. |
| Contact roller plastic spring washer is worn. | Replace if necessary. See parts replacement guide. |
| Tape not clinging to Contact Rollers. | Dust contact rollers with baby (talcum) powder to increase static clinging of tape. |
| Blade is dull or dirty. | Replace or clean, as necessary. See parts replacement guide. |
| Tape quality is poor. | Review suitability of tape roll for application. |
| Tape head position too high. | Ensure tape head side plates are within 1/16 to 1/8” of the case. |
Top Flaps Slightly Open
| Possible Causes | Solutions |
|---|---|
| Case is over-filled, preventing flaps from fully closing. | Ensure cases are not over-filled. Ensure case dimensions are suitable for the product. |
| Tape Tension is too weak to pull flaps down. | Tighten tape tension accordingly. See user manual. |
| Tape head position too high. | Ensure tape head side plates are within 1/16 to 1/8” of the case. |
Tape Wrinkled on the Case
| Possible Causes | Solutions |
|---|---|
| Tape Roll Hub Adjustment too strong, causing tape to recoil when cut. | Loosen Tape Roll Hub Adjustment. See user manual. |
| Tape Tension is too strong, causing tape to recoil when cut. | Loosen Tape Tension accordingly. See user manual. |
| Contact Roller pressure is too strong. | Decrease Wipe Down Force of Contact Roller. See user manual. |
| Contact Roller seized or hard to turn. | Replace contact roller(s). See user manual. |
Lengthwise Wrinkling
| Possible Causes | Solutions |
|---|---|
| Tape head position too high. | Ensure tape head side plates are within 1/16 to 1/8” of the case. |
| Under-filled Case, causing the flaps to sag inwards as the contact rollers press and apply tape. | Reduce the Wipe Down Force spring tension. Ideally, have the case size fit the product. See user manual. |
| Tape threading incorrect. | Ensure tape threading follows the guiding arrows on the tape head. See user manual. |
| Tape Roll Hub Adjustment too strong. | Loosen Tape Roll Hub Adjustment. See user manual. |
| Tape tension is too strong. | Loosen tape tension accordingly. See user manual. |
Top Flaps Overlap at Case’s Center
| Possible Causes | Solutions |
|---|---|
| Incorrect case dimension. | Contact case supplier. |
| Side Guides or Conveyors are too narrow or tight. | Widen or loosen Side Guides or Conveyor Belts. See user manual. |
| Contact Roller pressure is too strong. | Decrease Wipe Down Force of Contact Roller. See user manual. |
Tape Tail Cut Unevenly
| Possible Causes | Solutions |
|---|---|
| Blade is dull. | Replace Blade. See parts replacement guide. |
| Blade is dirty. | Clean the blade and apply a little silicone or oil to avoid adhesive buildup on the blade’s teeth. Never use a hard or metal object to clean the Blade. |
| Tape Roll Hub Adjustment too strong. | Loosen Tape Roll Hub Adjustment. See user manual. |
| Tape Tension is too strong. | Loosen Tape Tension accordingly. See user manual. |
| Tape quality is poor. | Review suitability of tape roll for application. |
| Tape head position too high. | Ensure tape head side plates are within 1/16 to 1/8” of the case. |
Tape End Stuck to Itself

|---|---|
| Tape Roll Hub Adjustment too strong. | Loosen Tape Roll Hub Adjustment. See user manual. |
| Tape Tension is too strong. | Loosen Tape Tension accordingly. See user manual. |
| Contact Roller Plastic Spring Washer is worn. | Replace Plastic Spring Washer. See parts replacement guide. |
Major Flaps Folded Over
| Possible Causes | Solutions |
|---|---|
| Contact Roller pressure is too strong, causing top flap edges to peel back. | Decrease Wipe Down Force of Contact Roller. See user manual. |
| Case not square during sealing. | Ensure case is square when entering case sealer. |
| Poor case quality. | Contact case supplier, regarding the Case Joint (corner glue lap) as a possible cause. |
| Tape head position too high. | Ensure tape head side plates are within 1/16 to 1/8” of the case. |
Tape Wrinkling on Top Leading Edge of Case
| Possible Causes | Solutions |
|---|---|
| Tape head position too low. | Ensure tape head side plates are within 1/16 to 1/8” of the case. |
| Obstructions on the tape head or tape head mounting interfering with the tape. | Remove the obstruction. |
| Tape head is not level. | Check tape head mounting. See user manual. |
Tape is Off-Center
| Possible Causes | Solutions |
