It will be like a zig-zag line not straight line like the original,

 

I've tryied to clean everything inside the printer, i did many calibration and printhead alignment and upgrading the firmware, i get access to the service menu and i test each part and component and module and carriage assembly, also the IDS and service station, all pass without issue, also i tried to change the paper media and size, still the same thing.

 

Is there any one have experience on this issue so he can help me with this matter

 

 

Thanks in advance

Best Regards,
