Issue / Question
ZT600 series printer's peel sensor can not work after installing the rewind upgrade option.
After performing media and ribbon manual calibrate, the peel sensor can work properly but after restarting the printer, the peel sensor does not work properly again.
ZT610, ZT620, ZT510, ZT610R, ZT620R
Resolution / Answer
Send the allcv string to the printer - Using the SGD Allcv Command ! U1 getvar "allcv" <CR>
When you check the allcv data, you can find the below:
device.rewinder_installed : no
sensor.peeler_present : Not Present
These parameters cannot be modified by using ZPL or SGD command.
Install the rewind module jumper cable to J22 on the main logic board (MLB).
The jumper cable indicates that the rewind module is present.
After install this jumper cable, check the allcv data again, you can find below:
device.rewinder_installed : yes
sensor.peeler_present : Present
Sometimes it is necessary to do the media and ribbon calibration again, and then the peel sensor will work.
*If you lose the Rewind Module Jumper Cable, you can purchase it with part number - P1083320-046.
