I've never had the pleasure of seeing this on any FR/GR/RA's but I watched your video.

Have you rigged the master making cover safety switches and watched it load the master onto the drum? Is it parallel there?

Check that the gold U hooks on both ends of the TPH are seating properly around the collars of the write roller. Whichever end (front or rear of machine) is burning the image should be OK. I'm thinking the TPH isn't coming down and seating properly on one end with the write roller so you are only getting tension from one end and only image burn on that end as well.

That's just my cents. Good luck

Your right the gold hook isn't going down all the way on the side that's not burning! How do I fix this? Thanks !

De-burr whatever is catching with a file. Grease the parts. Bend the U hook with a pliers if you can. Just be gentle cause if you damage the TPH surface you are going to kick yourself.

THANK YOU!!! Finally working again the hook had burs and was bent to close together.
