Table 11. Printer Problems and Solutions
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. 300 dpi = .0264 inches.
203 dpi = .04 inches.
2. Check that Media > Image > Clip Page = Enable. 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.
1. Make sure the ribbon is installed correctly.
2. A poor ribbon/media combination can cause insufficient
friction between the media and ribbon. Verify that the
correct ribbon and media are being used.
3. The printhead pressure may not be set high enough. Set
the pressure higher.
4. There may be adhesive on the printhead. Clean the
printhead.
5. Verify that Media > Handling > Print Mode menu is set
for Transfer and not Direct Thermal.
1. Verify that Print Intensity is set to the proper level in the
Media > Image section.
2. Verify that Media > Handling > Print Mode menu is set
for Transfer and not Direct Thermal.
1. Check that the media sensor is clean and undamaged.
2. Check that the gap between the bottom of a label and the
top of the next label is at least 0.100 inch. Use only labels
and tag stock approved for this printer.
3. Inspect for a jammed label. Remove the jammed label.
4. Check that the transfer ribbon and label stock are routed
correctly.
The Ribbon Width value is set too large, which causes too
great a ribbon take-up and ribbon supply spindle torque.
Reduce the Ribbon Width value to decrease the torque on the
ribbon spindles. The Ribbon Width value should be very close
to the Label Width value.
To reduce the torque further, set Media > Ribbon > Ribbon
Width from Same As Paper to Set In Menu. Then set a value in
Media > Ribbon > Ribbon Width Adj that is less than the
installed ribbon width.
