Hello everyone, 

 I am using step files for better automation in working with PCB. But I can't determine the dimension step files. Please help me out from this, it is urgent for me.


I upgraded my PC to Windows 7 and I have uninstalled the old drivers installed on it. I have downloaded the new drivers from Canon site. When I try to install the new drivers I am getting the Message: "Need to uninstall old drivers first". I have cross checked it thoroughly, but Somehow the older drivers had not been removed.

I am not able to install the new drivers by connecting the printer via USB port, nothing happening in the computer.

An older version of MF Drivers exists in the computer.
