Zebra Z4M Plus

you should recalibt=rate the printer.
Are you sure that your previous label was not longer?
With the autocalibrate function activated the printer should try to detect the correct length. If it doesn't the yoou have
- A problem with the label border
- Preprinted stuff which the printer detects as to fo feed

Hi, if is the vertical line, its the print head that need to be replaced,
try to clean the print head and try this to confirm:
turn printer off, press PAUSE button and at the same time, power on, don't release the button, please wait until printer LCD screen come on, then release button. It will print the PAUSE test and after few 3-4 prints, u can turn off and on again otherwise printer not ready to print your labels until u restart it. (pause test stops after 10-15 labels). this pause print just show how the print head is and if come with vertical lines, u will need to replace. other idea is (if u can) turn the bar code different position or on vertical way at label format. Thanks.

Check for missing teeth on the main drive belt.

Check the label size is set correctly in the application. Try using a driver from Nice Label or Seagull Scientific websites to suit Z4M (Not Z4M Plus). Recalibrate the printer and try again. Remember to setup the driver correctly because the driver will override the printer settings.

Is the length of the label correct on the configuration print out?
Else try t check if there isn't a feed or print adjust in the parameters

Restore factory defaults. If this doesn't sort it out, get back to me and I should be able to point you towards the right solution.

Might foul the ribbon sensor, clean the sensor and try to print again.

The printer is Z4M or Z4M plus? I found this error at z4m plus and the solution is to change the motherboard. Roberto Martinez Mexico bartech9@yahoo.com.mx

in the setup menu there is an option to choose what the machine does on powerup and head close. Yours is probably set to calibrate. Just change that setting to "none". Same thing with the pausing. there is a setting to pause after printing each label. Just change that option.
