Stops Printing

2. Reset to Factory defaults: Hold down the single round button on the front panel. The indicator light will start a flash sequence, 1, 1-2, 1-2-3 & so on. When it flashes 4 times, release the button. 
3. Label width calibration: Hold down the button single round button until the light flashes 5 times, then release it. This will make the printer enter label width calibration. It will print a series of widths, getting wider each time, on a label. When the printed width matches the label width (or your preferred setting), hit the button once to lock it in. 
4. All other calibrations: Hold down the single round button until it flashes twice, then release it. This will run and print an automatic set of calibrations.  

Misaligned Printing- My Printer is Printing Blank Labels

If your printer is printing many BLANK labels the yellow plastic alignment head probably needs to be adjusted. 

How to adjust the alignment via Zenput Labels:

  • If the printing seems misaligned, go the Settings page in the Zenput Labels app. Press on Calibration and follow the on-screen instructions to manually align the printer. 
  • If the printer prints 4-6 stickers at a time and then is off-center check to make sure the printer alignment control is aligned correctly. 
  • Once adjusted, perform a smart calibration as well as force quit and reopen the Zenput Labels app. 
  • Here is a link on how to perform a smart calibration 

It needs to be adjusted like in this photo:

Labels are printing light /illegible

On the back of the printer, you'll find a switch (pictured below) that changes the darkness of the printing. The left setting will be the lightest and the right setting will be the darkest. Try moving this switch and check if you get the desired printing darkness. If not, move on to the manual calibration instructions below.


To manually calibrate the darkness, follow these instructions:

  • Press and hold the "pause" button until all lights flash yellow, then let go
  • The "status" (diamond in a square) light should be yellow
  • Press the "feed" (middle) button twice
  • The "data" (folder with an arrow) light should be lit (if not, keep pressing "feed" until it is)
  • Press "pause"
  • The printer will start at the lightest print setting and will start printing labels slowly, one at a time, with increasing darkness
  • Once it prints out an acceptable level of dark label (8.0 or 12.0 will probably be good), press the "feed" button again.

Zenput labels are printing out blank 

The common fix for this is to ensure that the printer is set up for Direct Thermal . 
Also, make sure the correct labels are being used.  

Out of labels?
