I have been trying to print but not everytime I send a print, in prodution manager it will rip but then says "cannot open port" something has happend in the printer that will not allow it to print anything.

It sounds like the machine got reset for whatever reason. The IP address probably reset back to the default. You'll need to go into the Setup menu and change the IP address to whatever it is set to in your RIP.

Yes, something happened to the port during that process. I ended up having to rebuild the port and change the IP addresss on the printer then change it in production manager. I have leared ALOT during this process and I really appreciate you help and quick repsonses. I have got the printer back printing but I am not out of the woods yet. Im still unsure if the CR code is going to be an issue, I will update when I find out.

Well, was able to print 2 4ft prints and half way through the 3rd the original E074Err CR2 Current code happened again. Not sure what to do at this point...

It could be a few things. Unfortunately, all the easy things are ruled out at this point.

There could be a small amount of drag that you can't feel when moving the head back and forth manually but it's enough to cause the motor to require too much current to move when it's at full speed. You cleaned the rails but it could be one of the pulley bearings or even the bearings that ride along the Y bar.

The motor itself could be bad which is rare but not unheard of.

The motor driver chip on the main board could be malfunctioning and causing the current issues.

Although it seems like the encoder system is working, it may be intermittently misreading the encoder strip and the error adds up to a problem. I'd expect an encoder error with this but since the systems are connected, they can cause weird errors that don't seem to match. The long trailing cables could be failing which would also mess up the encoder data as well.

Unfortunately, there aren't really any more advanced electrical troubleshooting guides to narrow it down. The Mutoh manual will just tell you to replace the parts and hope for the best basically.

Yeah, at this point im not sure what to do besides order a new motor and encoder strip. I was just able to print another 4ft section with no issue at all. So the error occurs randomly which makes it harder to diagnose.

Good Morning,

I had a clogged print head which was causing me some issues but I have resolved that and started back printing. I was able to print 3ft before it through the CR code again....I am currently at a loss and not sure what to do at this point.
