The MMC command does not always cut



Audience

Hello,
 
I am having trouble printing with ZPL code. And I hope somebody can help me with it.
I have set up my ZPL code to print and cut the label.
 
^XA
^MNM
~TA015
^MMC
^FO10,10^BQN,2,5^FDQA,61842215H^FS
^XZ;
 
The MNM command should cut, but with 10% of our labels when send the commands, the zebra printer, print the label but not cut.
We have the Zebra KR403.
 
 
I hope any of you can help me!
Thanks in advance.
