If the paper works out of another tray with no problems it would seem that the problem is in the paper path from tray 1.

Had an issues similar, same machine and finisher. I had to install tray heater, lots of curl because client refused to use decent paper. If you don't have curl probably not the issue. How about an unlevel floor maybe throwing off the path between copier and finisher causing binding or drag.

Yeah, could be an issue with the tray 1 vertical transport guide. They break and/or come dislodged easily.

Where is the tear on the paper located? Towards the middle on the lead edge?
You mention replacing the drive for the feed units?, but not if you replaced the feed rollers (usual cause) or the torque limiter.

Since you included the finisher type in the post title, I have to ask. Have you disconnected the finisher and tried printing without it? If all is good, then you may have to adjust the angle of the finisher entrance guide. They get bent easily and will cause misfeeds.

Can I get a little more info on adjusting that guide. Thanks

There is no actual adjustment. You just have to eyeball it and take a former and bend it or a bender and form it. FYI, a former is a tool used for straightening type bars on old type bar typewriters. A bender is a pair of pliers.

What I have had trouble with is that when customers decide to relocate their equipment themselves and remove the finisher to move separately they do know realize that there are NO LIFT POINTS on the side of the finisher that is normally against the copier. Every cross member in there is not designed to be used as such. They are thin sheet metal and extremely easy to bend.

The only tray that gives any trouble is the first tray which is letter long edge feed only. I ran it without the bridge and finisher with a small amount of wrinkling but no tear in the paper edge.

It is not uncommon for the teeth on the side rails that allow both rails to move together to get chipped. This allows both rails to move to either the front or rear by as much as a half inch. This increases the chance of the edge of the paper to run against a guide elsewhere in the paper path, such as the entrance to the finisher.. Take a known good tray and try swapping.
