Label wraps around the
platen roller. 1. Open the pivoting deck by rotating the blue deck lock lever
counterclockwise.
2. Remove the front cover thumbscrew and front cover from
the printer for better platen access.
3. 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.
4. When all of the label is removed from the platen, use an
isopropyl alcohol wipe, Printronix PN 254945-901, to
remove all adhesive from the platen to help prevent any
future label wraps. Replace the front cover and its
thumbscrew.
5. 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 this adhesive contacts the
platen and when the label advances forward during
printing or a Form Feed, it wraps around the platen.
6. Avoid label wraps by having the user practice careful tear
off techniques and ensuring that the label cross
perforations are ideally positioned at the tear bar edge by
using the correct Tear Off Adjust value in the MEDIA
SETUP menu.
Print is too small or too large. Ensure the proper printhead is installed (203 or 305 dpi).
• Print quality is good, but
the printer skips every
other label.
• An occasional blank label
occurs within a print job,
but no labels are lost.
1. Make sure that the label is not formatted too close to the
top edge of the form. Leave white space equal to eight dot
rows at the top of the label. 305 dpi = .0264 inches.
203 dpi = .04 inches.
2. Check that Clip Page = Enable in the MEDIA SETUP
menu. Clip Page = Enable causes any printable data to be
clipped off and lost once the next TOF position
(transmissive gap, notch, hole, or reflective mark) is
detected. Clip Page = Disable allows the printer to ignore a
gap or mark. The printer looks for the gap or mark after the
specified Label Length is first reached.
