Replacing Mimaki CJV Cut Carraige and Mechanical Drawing?

Hey guys, thank you for taking the time to read this. First off, just wanted to say thanks to everyone for their support and help.

We are using a Mimaki CJV30-130 and I'm having trouble finding any parts catalog/mechanical drawing. The specific part(s) I am looking for right now is an entire cut assembly/carriage as well as the individual parts that make up the entire assembly. I have spent quite a while searching for this and there doesn't seem to be much information out there.

I am hoping to find a mechanical drawing of the entire machine and the individual parts so that in the future, I can more easily locate replacement parts.

As for the cut assembly, I found these two products and I'm confused on what they are. It would make sense that the "Cutter assembly" is what I'm looking for but I've also heard it referred to as a "Pen assembly". If anyone could shed some light on this for me, I would appreciate it.

Just to be clear, I attached a picture of the exact part I'm talking about as well as two links to the cutter assembly and pen assembly.

Thanks again for your time!
