Sensor Profile

Use the sensor profile image—which typically prints across several labels or tags—for diagnostics if the printer is not accurately sensing gaps between labels or if it incorrectly identifies pre-printed areas on a label as gaps.

To print a sensor profile using the printer buttons, turn printer power OFF, then turn printer power on while holding down

FEED

(

) and

CANCEL

(

) simultaneously. Continue pressing these buttons until the Status indicator is the only indicator that remains lit.

To print the sensor profile using Zebra Programming Language (ZPL), send a

~JG

command to the printer. See the ZPL Programming Guide for more information on this command.

Compare your results to the examples shown in Performing a Communication Diagnostics Test. If sensor sensitivity must be adjusted, calibrate the printer. See Manually Calibrating Media.

Sensor Profile (Gap Media)

Sensor Profile (Black Mark Tag Media)

1	MEDIA (media sensor readings line)
2	WEB (media sensor threshold settings line)
3	OUT (media out threshold line)
4	Upward spikes indicating gaps between labels (the 'web')
5	Lines between the spikes (indicate where labels are located)
6	Measurement in dots (from the start of the printout)

Compare the sensor profile printout to a length of one media form (ex., a label). The spikes should be the same distance apart as the gaps are situated on the media.

If the gap distances are not the same, the printer may be having difficulty determining where the gaps are located.
