Zebra 4M won't calibrate, keeps trying but never does then read error paper out.

Do a calibration from the panel and check that your paper remains under the sensors when printing.

some labels are hard to calibrate, nee to calibrate the sensors with manual calibration.
1} go to the MEDIA AND RIBBON CALIBRATION,
2}take 2 or 3 labels from the base paber, load the way to the based paper stay unther the sensors, 3}close printhead.
4} press ok.
5} Move the ribbon out from sensors and close the printhead.
6) press ok
7) wen printer ask RELOAD ALL, load the labels correcly and the ribbon, close the printhead and the top door, and press ok. The printer run the calibration it self.
wen finish, saved (press setub twice) and test.

Try disabling the ribbon sensor for the white ribbon by changing from thermal transfer to direct thermal.

run the sensor profile, check if check the gap, run manual calibration, if ask for reload media, please take 3 or 4 labels from the label rolar, put through the sensors (check if ribbon(if use) is install on the correct spots and don't stop the sensors to read the gaps) and run the manual calibration.

You have a bad logic bd and it needs to be replaced our repaired.

The printer is dirty sensor label or no label is calibrated. Turn off the printer and press FEED, CANCEL, PAUSE and turn on, release the keys to advancing the label, and let print be calibrated. Roberto Martinez Mexico [email protected]

You get the error because the printer doesn't see any paper.
There are paper guides that need to be set for the size of the labels being printed. If you are switching from a 4" wide roll or sheet to a 3 1/2" label, you will have to move the slider in about 1/2". You will also have to calibrate the printer when you change label stock. If it won't calibrate, make sure the photoeye is hittint the break between labels. The photoeye is located where you insert the labels into the printhead path.

Ok so the printer is calibrating and printing which means the fault lies with the display, or power to the display pcb. Check the fuse on the mlb, if that is ok then order p/n G79302M (display panel)

chek on setings if the sennsor is reflective, transmissive or auto.
should be on Auto. try to read the Sensor profile, and check if read the gap.
Try the Manual calibration, and then run the sensor profile.
tur off and on again.

try to run the manual calibratio from the setings.
run "manual calibration"
move the ribbon out from the sensor (with the print head open) and take out 3 or 4 labels from the rollar and put that blank label paper unther the sensors on the left,
say "ok"
wen appear "reload all"
put the ribbon and the normal labels on the correct possition, and say "ok"
try to run sext the sensor profile.
save data (twice on "setup button")
tur off, and on again.
