HP 4+ Error 13 paper jam

My laserjet 4 Plus shown "13 Paper Jam". It started when I tore a jammed sheet while trying to pull it out from the bottom of the printer between the toner and the paper tray. I’ve looked, but there may still be a scrap in there or a sensor that needs to be reset, I’m not sure.

Under Sensor Reset instructions, none is listed for 4+.
Also under Paper Sensor Locations, the photos for 4+ don’t look like anything I can see on my machine. I wish I had a service manual.

Under Repair Kits, I don’t see a kit listed for a 4+ that addresses this problem. [I did successfully install the 4+ Exit Jam kit a few months ago.]

I also looked at a long list of similar Error 13 problems on your Forum but didn't see anything I could use.
I need some help.
If you pulled the paper out from where you said, then it hasn't gotten anywhere near the fuser. There is a registration sensor in front. If you pull up on the green handle under the toner cartridge, it is over on the left side under the metal plate you pulled up.

the way i find this jam is to remove the paper input assy. remove top cover 2 side covers the bypass tray and guide. the 2 screws on the left side and 4 screws on front side. one connector and the paper input assy is out. you then can see the u turn where the paper can stick.

I just hope you opened the back of the printer to make sure there is not a sheet of paper almost out of the fuser heading up towards the exit assembly. If the print job was a multipage job it is possible when the paper jammed it stopped the printer and there is still a piece of paper at the back.

Well after an email from Moe pointing out that to see the fuser exit sensor, I had to remove the top cover, that's what I did.
Then I noticed no paper scraps, but a missing screw to hold down the fuser unit. I found one that fit, closed it up, and my printer now works!
Was the problem it a loose fuser unit? a reset when I pulled the power plug? I don't know, but thanks to all of you for keeping me trying.
