I have a customer that brought me a hp4100n printer, problem is it jams with code 13.6 error I can go into paper path test and print 1 sheet from tray2 and its fine but try and print 10 sheets from tray 2 and it prints all 10 sheets and then jams with a blank sheet 1 inch out of the fuser and the trailing edge is just past the reg assy. if I pull the jam out and reset it will push 1 more sheet of blank paper through the printer and to the output bin and come to ready state. I have installed a Maint kit and still does same thing. Ive done cold reset, same thing. you can run paper path test from the tray 1 and same thing. tried swapping formatters same thing.........any thoughts?

Check the fuser flag ...
or just Swap fusers?
See if it goes away...

You need to run paper from mp tray. This will tell you everything about tray 2 is working. Look in behind Tray 2, is the paper deck assembly moving the paper?
The problem is paper feed assembly if these area's check out

You need to run paper from mp tray. Replace the pca board

Yes I have printed out of tray 1 and tray two with the same results, if you run a config page it says the size selected is letter, also when you print a paper path test it also shows the size as letter, so I doubt its the pca.....usually if it were the pca it would show a different size on the test run and also on the config page

Ive checked the fuser flags and even replaced the fuser with the same results. the problem is when I run the paper path test it will print all 10 sheets correctly, BUT! after the 10th sheet eject to the output bin it keeps sending paper through like it is still printing but the paper is blank, after it prints the 10th sheet out it suppose to stop, not keep sending paper through the printer

Engine control board

Again! Weak springs, and dirty sensors! Worn feed/reg assy's, and rollers.
The floating sensor, {reg. assy.} has it's own small pca, and can be the real culprit here. HP denies it exists, and when pressed, will send it with the wires too short to connect. It is hard-wired, and only one connector.
Any unit with over 150,000 pgs, needs to completely refurbed, not just piece-meal replacement as occurs. Reality: Printing is not cheap.

It might require swapping quite a few parts to find the source of the problem. It could be sticking solenoids on tray 1 and 2 pickup assemblies, but the odds of that happening on both assemblies seems remote. Could be paper path sensors at the registration assy or paper feed assy, could be engine control board. This is one of those rare problems that might get fixed with the first part you swap, or it might be better to get another printer because of the time required to find out the culprit.

I tried new reg assy and paper feed assy, same prob, tried a drop of super glue on the sensor flags to build it up sense it looked worn on the tip, same prob..... Im begining to think it just might be an Engine controller like red cow mentioned because, it feeds paper fine, the problem is anything more than 1 sheet of paper, aka pcl fonts ect.... 2 ,3 ,4 or more sheets of paper sent through it. it always finishes the job plus 1 more blank sheet, the blank sheet stops inch or so out of the fuser. that tells me the engine controller isnt telling the feed rollers to stop after the last page of the job sent. instead it fires the solonoid 1 more time which feeds 1 more sheet of paper through causing it to stop in the fuser and declare a 13.6 error. the engine controller is what gives the command to the solonoid that releases the pickup rollers to feed paper.... tell me what you guys think?

i had this prob and i toke all the covers off blew it out with a air compreser it must be done with a air compreser to be sure you get all the dust out some times dust gets on the sensors

That was the first thing I tried, air compressor, still has same problem
