DesignJet T520
macOS 10.14 Mojave

I recently moved my T520 to my new office (which entails putting it in a car for transport) and within a week I have a new issue: when printing, the carriage will randomly pick up the cutter and cause a paper jam. This happens to about every third or forth print.

 

I took apart the cutter assembly to make sure there wasn't an issue there and noticed a crack on the plastic gear holding the lower knife down, which I 3D printed and replaced. I reseated the cutter, and it was good to go for a few days. Now I'm having the same issue - the carriage will print about 1/3-1/2 of the print, then accidentally pick up the cutter assembly and jam.

 

I've had the printer for just over over a year (so it's out of warranty) and am using the same paper as I always have.

Good morning,

 

There is any noise when cutting? if yes it's recommended replacing the cutter assembly else to check the cutter holder in the carriage assembly.  (its the mechanism of engagement and disengagement of the cutter)
