I need to know what the difference is between a Z4m and a 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

There is a printhead hot error that will come up on the printer if it overheats the printing mech and it will pause. If it totally locks up I'd suspect the main logic.

Z4M ZEBRA 77904M PWB MAIN LOGIC Z4M Refurbished
Z4M Plus ZEBRA 34901 010M PWB MAIN LOGIC Z4M Z6M Refurbished

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.

You need to find a local Zebra Authorised Repair Service agent, go to http://www.zebra.com and look in your country.

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.

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 [email protected]

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.

We had a computer tech change the CMOS battery inside the printer and the display starts to work again.

this is a color printer or not
