This is intermittent. It does not happen with every print job. A multiple page job can & does print correctly.
The paper properly moves forward under the star-wheel ass’y & carriage assembly and then properly moves forward into the next set of feed rollers.
The paper is moving up into the stacker and the leading edge of the paper does pass smoothly at the “ramps” “values” & other rollers. About halfway up into the stacker I can see the paper stop moving and I hear the paper advancing inside the plotter. The carriage then paper jams into the “humped up” paper (see pic) and then the expected 86:01 error.
It is as if the paper feed assembly located before the carriage ass’y advances the paper and the feed assembly after the carriage does not advance the paper.
