What's causing this?

I had problems last week with my Roland VS640 printer stopping in the middle of a job. The head stops on the control panel side, but with a light tap on the side of the printer it would go again. It would make one pass, then stop. So every time it came back to the control panel side and stop I tap the side and it goes again. This happened about 7-8 months ago and I cleaned the encoder strip & did a limit initialization and it has worked fine ever since, until now. So today I did the same thing, cleaned the encoder and did the limit initialization. This is the first print I tried...it printed like this and only printed this much and stopped. Anyone have a clue as to what caused this.

This still looks like encoder strip issues. Probably time for a new strip or new sensor.

Thanks I did go back and clean the strip again and it got better, but still has a little bit of an offset on some parts of the print.

Just started a print and while printing the first crop marks it stopped on the left side, beeped and shows carriage separated.

Here's what the crop marks that printed looks like.

Update: It seems it was the encoder strip, I unhooked the left side and pulled the strip up as much as possible and cleaned the strip again with 91% alcohol. Then did the limit initialization again and problem solved...for now at least.
