MAX Electronic Check Writer EC-310

Operation confirmed. Printing was successful without any issues.
If needed, I can also ship the printed test paper (shown in the second image). Please let me know in the comments or via transaction message if you do not require it.

There are no noticeable scratches or stains, and the overall condition is clean. However, the instruction manual is missing.
You can find a PDF by searching on Google, so you can operate it without any problems by referring to that.

This is a used item that has been stored at home for a long time, so please refrain from purchasing if you are concerned.
