Table 16. Printer Problems and Solutions (continued)
Symptom
Media and ribbon move, but
no image prints in Thermal
Transfer mode.
When narrow media is
installed, the media moves
but no image prints.
Printing is faded or of poor
quality.
Print is light on the left or right
side of the label.
Prints strange characters
instead of the correct label
format.
Solution/Explanation
1. Print the Checkerboard diagnostic test pattern and check
that the image appears on the used portion of 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.
2. The ribbon may be designed for another model printer.
3. The ribbon may not be compatible with the media.
Verify 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 both latches on the pivoting deck are 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. Try increasing the pressure.
4. Verify that the Print Speed and Print Intensity values are
correct. Adjust Print Speed and Print Intensity in the
QUICK SETUP menu, MEDIA CONTROL menu, or via
host software.
Check if the pressure blocks are set for the width of the media
being used. Set each block near the edge of the media.
1. If the printer serial interface is being used, check that the
printer serial baud rate setting matches the baud rate of
the host computer. Reset the printer via software, or turn
the printer off and then on.
2. Check if the printer serial host interface is set for 8 data
bits but the transmitting device is set for 7 data bits (or
vice-versa). Check the current setting by viewing it on the
LCD, and use the SERIAL PORT menu to adjust the
settings, if necessary.
3. If the printer parallel interface is being used, make sure the
parallel interface terminating resistors are correct for the
host computer drivers.
