Mutoh rj900x blurry prints

I'm having a big issue with my mutoh rj900x.
When i start a new print...the first few passes are fine...but it goes blurry...and just keeps getting worse.
I thought maybe it was bad roll of paper, as i had just changed the roll...but the other roll i put on does the same thing.

What lead up to this was...
I was printing and i ran out of paper...when this happens, the paper is glued to the end, so the printer just keeps trying to pull paper so it keeps printing overtop of its self. When i saw this was happening (i was in the other room) i stopped it and changed the roll.
Now its doing this.
I wiped clean the sensor strip.
