• The front/rearend detection of the sheet has failed.

If there is paper dust or dirt accumulated on the sheet sensor, the front/rear end of the sheet may not be properly detected, resulting in incorrect operation such as the sheet falling off due to continuous feeding.
Please clean the sheet sensor with a cotton swab or similar tool.

---

* If the failure is caused by using sheets that cannot be detected at the front/rear ends,
 you can also turn off the sheet sensor function. If you turned off the sheet sensor function,
 the presence or absence of a sheet or the front/rear edged of the sheet cannot be detected,
 so be sure to set the [CUT AREA].

* The detailed procedure for turning on/off the sheet sensor function and setting the cut area can
 be found here.​
