Problem
Media is not fed correctly.
A data transmission error appears on
your computer.
Solution
 Is the print head or platen roller dirty?
Although the print head generally remains clean under
normal use, dust or dirt from the platen roller may become
stuck to the print head.
If this occurs, clean the print head or platen roller.
For details, see Print Head Maintenance or Platen Roller
Maintenance on page 51.
 Are the sensors in the correct position?
Check that the sensors are correctly positioned. For details,
see Checking the Sensor Position on page 17.
 Has the paper size information been registered with the
printer?
If the paper size information has not been registered with
the printer, the media will not be fed correctly.
For details, see Registering Paper Size Information With
the Printer on page 9.
 Is the correct port selected?
Check that the correct port is selected.
 Is the printer in cooling mode (the POWER indicator is
blinking in orange)?
Wait until the indicator stops blinking, and then try printing
again.
 Is someone printing via the network?
If you try to print while other users are printing large
amounts of data, the printer will be unable to accept your
print job until ongoing printing is finished. In such a
situation, execute the print job again after the other jobs are
completed.
