Known Issues
Printing Variable Data on Continuous Media Results in Blank
Media Feeding
This issue results from printing under the following conditions:
• In the Media tab of the printer driver, None is selected as the Sensor type (continuous
media).
• The print job contains labels with variable data such as barcodes or serial numbers that
change during printing.
When printing under these conditions, and there is no more data available to print, the printer
will not pause and wait for more data. Instead, it will continue to feed media as if printing. This
has the potential to create long sections of unprinted media.
To resolve this issue, enable the Buffer option in the General tab of the printer driver. The
entire job will be rendered in the spooler before it is sent to the printer.
This issue does not occur when using Gap or Reflective as the Sensor type. The printer will
automatically pause and resume appropriately as data is received. It also does not occur when
printing static labels.

Color Shifts or Drops Out During Printing
This issue results due to loss of ink or excessive air in the ink lines internal to the printer.
To resolve this issue, perform the following steps:
• Cancel the print job and perform a “Prepare for Moving” sequence one time. There is no
need to physically move the printer.
See “Preparing for Moving” on page 77.
• Resume printer use. If problem continues or recurs, reseat the printhead by performing a
“Replacing the Printhead” procedure and either replace the printhead or reuse the same
printhead in the procedure.
See “Replacing the Printhead” on page 80.
• Resume printer use. If the problem persists, contact Technical Support.
Powering On with the Main Side Door Open Results in
Incomplete Initialization
When the printer is powered on, components within the printer are initialized and prepared for
use. You will be able to hear these components mechanically adjusted as the printer completes
this routine. However, if the main side door is open, this sequence may be interrupted and the
initialization process will fail.
This condition is not indicated by an error message. The initialization process will stop and only
the sump pump motor will be running. To correct this issue, ensure the main side door is closed
prior to powering on the printer.
