Table 12. General Symptom List
1. Print a checkerboard diagnostic test pattern (page 196)
and check if the image appears on the used portion of the
ribbon. If the image is on the ribbon, the ribbon may be
installed with the transfer side against the printhead,
instead of against the media. Reinstall the ribbon.
2. The ribbon may be designed for another model printer.
3. Verify that the ribbon and media are compatible;
incompatibility can cause extremely light printing. Match
the ribbon to the type of media being used.
4. Check that the transfer ribbon is correctly routed. Route
the transfer ribbon with the ink side out.
5. Check that the printhead assembly is properly closed by
pressing down on both sides of the pivoting deck. Make
sure the latches on each side of the pivoting deck are
locked.
6. Check that the Label Width parameter value does not
exceed the width of the media installed. Set the Label
Width in the QUICK SETUP or MEDIA CONTROL menu.
7. The head pressure adjustment dial may be set too low.
Readjust.
8. The Print Intensity value is set too low in the QUICK
SETUP or MEDIA CONTROL menu or by host software.
9. The printhead pressure blocks are not positioned correctly
(horizontally). See "Printhead Pressure Block
Adjustments" on page 54.
Verify that the Label Width value in the QUICK SETUP or
MEDIA CONTROL menu agrees with the width of the installed
media. Too large a value will start the image too far to the right
and off the media.
1. Clean the printhead.
2. Check that the pivoting deck is closed and latched. Close
the printhead by pressing down on both sides of the
pivoting deck and rotating the deck lock lever fully
counterclockwise.
3. Verify that the head pressure adjustment dial is properly
set.
4. Verify that the QUICK SETUP or MEDIA CONTROL menu
Print Speed and Print Intensity values are correct. Adjust
Print Speed and Intensity in the QUICK SETUP or MEDIA
CONTROL menu or via the host software.
5. Refer to "Thermal Printer Media" and "Thermal Printer
Technology" on page 20.
