Symptom
After closing the printhead,
the printer continuously
moves the media back and
forth and briefly flashes the
message "RBN TAKEUP
FULL."
Wide width ribbon does not
take up properly. The ribbon
moves past the platen
assembly with the media.
The printer loses data from
the print job when an end of
ribbon condition occurs while
printing, even when Error
Recover is set to Enable.
Table 12. General Symptom List
1. Power off the printer and verify that the take-up spindle
rotates freely with no binding.
2. If binding exists, remove the side cover and check the gear
train.
3. Verify that the ribbon take-up motor is connected to J8 on
the controller board.
4. Replace the ribbon take-up motor.
The Ribbon Width value in the MEDIA CONTROL menu is set
too narrow for the ribbon installed. Set the Ribbon Width value
to match the width of the ribbon installed. This will increase the
torque on the ribbon take-up spindle.
Use a Printronix ribbon.
NOTE: Some ribbons use a trailer: foil or mylar material at the
end of a ribbon roll that is attached to the fiber core. In
order for the printer to detect a ribbon out properly and
then reprint an incomplete label, the ribbon supply
spindle must first spin freely after the ribbon parts from
it.
The printer can print with a trailer of up to 6 inches
long (the distance from the supply spindle to the
printhead). If the trailer is more than 6 inches, the
printer will continue to print over the trailer, with no
image being transferred to the label. A Ribbon Out
fault will then be detected when the trailer has parted
from the ribbon supply spindle, but may not reprint the
last label.
