Table 11. Printer Problems and Solutions
Symptom
Label wraps around the
platen roller.
Pivoting deck is difficult to
close and lock when heavy
tag stock media is installed.
Print is too small or too large.
Solution/Explanation
1. Open the pivoting deck by rotating the blue deck lock lever
clockwise and then open the front door and loosen the two
thumbscrews for better platen access.
2. Remove the wrapped label by slowly pulling and
unwrapping it from the platen.
NOTE:
Even though power is removed from the platen motor,
some drag will be felt as the platen rotates.
CAUTION
Never use a sharp object against the platen as cuts and
gouges in the platen may cause voids in the printed image
and require platen replacement.
3. When the entire label is removed from the platen, then use
an isopropyl alcohol wipe, Printronix PN 254945-901, to
remove all the adhesive from the platen to help prevent
any future label wraps. Tighten the printer front door
thumbscrews.
4. A label wrap occurs when a die cut label is incorrectly torn
at the tear bar by the user and adhesive is exposed under
the leading edge of the next label. When the printer pulls
this next label back to TOF, the adhesive contacts the
platen and when the label advances forward during
printing or a Form Feed, it wraps around the platen.
5. Label wraps can be avoided by having the user practice
careful tear off techniques and ensuring that the label
across perforations are ideally positioned at the tear bar
edge by using the correct Media > Image > Paper Feed
Shift value.
6. If Tear-Off Strip Media Handling mode is being used, you
can reduce the length of a label wrap, should one occur,
by setting Media > Fault > Label Missing menu to Early
Detect. This enables the Label Taken Sensor at the front
of the printer so that it will look for the first 1.3 inches of a
label. If no label is detected by the sensor during a Form
Feed or while printing, the printer will stop and display
LABEL WRAP: Open Head to Clear.
1. Set the printhead pressure adjustment dial to the MIN
position.
2. Close the pivoting deck and lock the deck lock lever.
3. Position the printhead pressure adjustment dial to the
desired head pressure setting.
Ensure the proper printhead is installed (203 or 300 dpi).
