not been completed for the product yet.
*2: If the printer can turn on but turns off right away, the protection circuit may cut off the power
due to an error such as a circuit failure.
*3: In case of "Not Trouble Found", check fatal error code.
If the reason for the return is evident, first check the phenomenon user

Paper Jam Fatal error
[Occurrence Condition]
This error occurs when CR Unit is
blocked by jammed paper.
[Major Occurrence Timing]
• Power-on timing
[Major Troubleshooting]
• Remove jammed paper
[NOTE]
On this product, if CR Unit
touches jammed paper, CR Unit
moves back in the opposite
direction so that customer can
remove the paper. However, if CR
Unit cannot move in this
sequence, this error occurs.
Paper Size Unmatch error
[Occurrence Condition]
This error occurs if the actual
paper length detected by PE
Sensor does not match with the
paper length specified in the
printer driver. (The error occurs
no matter when the actual length
is longer or shorter than the
theoretical length specified in the
driver.)
