•
Some complex labels with large graphic images can take a long time
to transmit to the printer (especially when using the serial interface)
and image in the buffer before they can be printed. Have you
allowed enough time for this process?
•
The On-Line LED will blink while the printer is imaging a label in
memory. If it is a very small label, the On-Line led will blink
quickly one time. If it is a long label, it will blink for a
correspondingly longer time.
•
If the On-Line LED does not blink, place the printer in the Hex
Dump mode and resend the data stream. A list of the received data
characters will be printed out in hexidecimal format. See Section 2,
Hex Dump Diagnostic Labels on page 35 of the Operator and
Technical Reference Manual for information on how to place the
printer in the hex dump mode. If the data cannot be printed in the
Hex Dump mode, the printer is not receiving any data.
•
Make sure your computer program is sending data to the correct
printer. More than one printer can be assigned to the same port in the
Windows Printer dialog box. Make sure the printer listed in the Print
Setup window is the CL408/412. (Note: The correct printer driver to
use for Label Wizard is labeled "SATO Generic")
The printer feeds a label, but does not print anything
•
Is the label wide enough? The first dot print position is on the
outside edge of the print head and narrow labels are justified toward
the inside of the printer. You may have to configure the printer with
an Offset value to correctly position the image on the label. Refer to
the Operator and Technical Manual, Section 2 for instructions on
how to do this.
•
If you are printing in the direct thermal mode, make sure you are
using direct thermal paper.
•
If you are printing in the thermal transfer mode, check to make sure
the ribbon is loaded properly with the ink (dull side) in contact with
the media.
Poor quality printing
•
If the print has sections missing, visually inspect the print head to
make sure it is clean and has no physical damage. If foreign matter
is observed, clean the head using a cotton swab and the Thermal
Print Head and Platen Cleaner from the SATO cleaning kit.
