I have a HP Latex 370 printer that needs to be worked on. I believe the rewinder motor with gears (B4H70-67066) needs to be replaced. It hasn't been rewinding the vinyl back up for quite awhile, but have still been able to print. However, the vinyl will shift and now that we are a little slower I thought it would be a good time to try and fix it. My question is if anybody has replaced this part and how easy is it to do. I tried looking up online with no luck. Thanks!
