Cause
"Media detection (blackmark/gap)" of the printer and
the media used may be different.
Check "Media detection (blackmark/gap)" of the printer
and the media used.
For details, refer to
When the reflective rate of the blackmark is higher than
the specified value, the blackmark may not be
recognized.
Infrared light is used for blackmark detection and the
infrared light reflective rate must be below the specified
value.
Check the specifications of blackmark printing, and use
the blackmark conforming to printer specifications.
Also, recognition may be possible by "Automatic
adjustment of gap and blackmark detection sensor".
Start the PrinterSetting from the printer driver. Select
"Detailed settings" and "Advanced settings" and execute
"Automatic adjustment of gap and blackmark detection
sensor" in "Calibration".
For details, refer to
If it had been working properly, the sensor may be
damaged. Request a repair.
Cause
To avoid paper jams, the mount of fanfold paper is
specified thicker than roll paper.
Because the mount is thick, gap detection may not be
possible even on genuine paper.
The usable label media range becomes wider by
adjusting the threshold value of the gap detector from
the driver; however, this is not guaranteed for all media.
Therefore, gap detection cannot be performed on
fanfold paper by the specifications.
In the case of roll media, gap detector can be used in
the specifications because the same original roll/mount
are specified.
