Thats interesting, so there must be something else causing the tray to be loose and giving the error, if i apply the minimum pressure on the tray like what will actually happen when theres 50 prints over it, the tray pops out only on the right side.

Also just noticed if i apply pressure with my hand on the right side of the tray, theres no jams after 30 prints. If i let go it jams on the very first print.

weird stuff.

EDIT: Just took some pics of the jam, paper gets stuck after coming out of the fuser and goes to the delivery tray, looks like something is missaligned on the inside of that paper guide.

Cleaned all the rollers, all of them rotate just fine, nothing seems broken and it doesnt make any crackling sound, it just jams everything.

No problem, what are the jam codes you are getting ?

"insert delivery tray" errors randomly. At first i thought it was a faulty or dirty sensor

I would go back to the sensor. The latch or what ever holds it in position or if it is doing it whilst just sitting there it is the switch i would think. my 2 cents.

error says delay, ive cleaned all the rollers and they dont look worn out, that delay i think is caused abviously because paper gets bitten just above the fuser delivery guide, its like something gets missaligned on the right side of the output tray, but i cant find what it is since everything looks normal, nothing busted or stuck, rollers move freely.

Re: HP MFP M4555 Enterprise tray problem.

Something sticky on the underside (closest to the printer) "grabbing" the paper? Had something similar on a P40xx. Paper would crumple (not bad, but enough to cause jam) behind tray 1. Removed the tray, looked at it. Didn't see anything. Put all back together. Same thing. Took apart again and REALLY looked it over. Found a tiny piece of label that had ripped off.
