Zebra MZ320 - feeds few lines after black mark is found

Question

I am working with Zebra MZ320 printer to integrate Black mark. I am facing issue when black mark is set to True. The printer feeds 2-3 line after black mark is encountered on paper

The command used to calibrate black mark successfully :

! DF CONFIG.SYS                        
! UTILITIES                                    
BAR-SENSE
LABEL                                     
PRINT

Sample print text :

! 0 200 200 700 1

I have seen many links that prevent extra feeding but they work with FORM / Continuous mode

Already visited and tried these links :

• Zebra iMZ320 image printing feeds too much paper
• Stop my mobile printer from feeding extra paper using continuous roll?
• Stop a Zebra Printer from automatically feeding lots of extra pape

It seems I am missing some configuration while sending commands to printer. Any suggestion is appreciated.

Sometimes these printers need calibration, did you calibrate it? See the calibration procedure in the user manual.

You can recalibrate the printer with Zebra Tools but also with ZPL commands. Sometimes only recalibration with ZPL commands helps.
