Recoverable errors
Although normal printer operation is no longer possible when recoverable errors occur, they do
not represent printer failure. You can recover from a recoverable error by turning on the power
switch or issuing a command from the driver after eliminating the cause.
Recoverable Errors
Error name
Roll paper
cover open
error(*1)
Autocutter error
(TM-L90 only)
(*2)
Paper layout
error (*3)
Note:
*1: Use the memory switch Msw8-8 to determine the cover open error as an automatically recoverable
error or a recoverable error. (Factory default setting is Recoverable Error.)
*2: With the TM-L90, if an autocutter error occurs due to a paper jam, turn off the power, remove the
jammed paper, and turn the power on again.
*3: When a paper layout error occurs causing by jamming paper while printing, turn the power off and
remove the jammed paper, then turn the power on again.
You can easily set the paper layout by using the automatic paper layout setting. Refer to "Paper
Loading Method" on page 55.
Error recover command is valid only when a recoverable error (excluding automatically
recoverable errors) occurs. When a recoverable error occurs, you can recover from the error by
sending an error recover command from the driver after eliminating the cause of the error; you
do not need to turn on the power switch again.
