Printer Paper Jams & Feed Issues

After over a year of successful printing with my HP Deskjet 4175e All in One Printer, I attempted to print a 4 x 6 photo using Microsoft Photo App, HP ink, and HP photo paper (4 x 6 gloss).  I loaded only the 4 x 6 paper and the first attempt resulted in the printer starting to feed, then printing a couple of passes, then stop with paper jam error.  I followed documented troubleshooting procedures and was unable to find the photopaper that had fed into the printer.  I went through the online trouble shooting procedures with no resulting fix.  I then attempted to print a second photo and  making sure all of my size selections were matched (they were). and began a second print.  Same thing happened and I could NOT find the 4 x 6 paper. 

At this point, I selected the letter size paper and removed the supply of photo paper and installed several sheets of 8.5 x 11 HP standard paper.  I tried to print a document and the paper began to feed and a few strokes of the ink carriage occurred then printing stopped with a paper jam error.  I was able to carefully pull the 8.5 x 11 sheet of paper out.  I spent an hour or so, searching all available orfices, slots, and accessible areas in the printer case, document feeder etc. and could NOT find either of the two photo papers that I had attemtped to print.   I then, again, went step by step through all available support videos, third party videos, and other HP and off line documentation with NO results of finding the lost paper.

I then uninstalled the printer driver and reinstalled my printer from scratch with the latest drivers.  I also check the internal visible areas for the lost paper and have yet to find those two lost photo papers.  

The next day, I started my printer and printed an Information Page which printed satisfactorily.  I printed a TEST page and the result was satisfactory.   I then printed two photos (4 x 6) and they both printed satisfactorily except one had slight black streaks on the backside from ink.  

It is not cost effective to return this printer to a service center for repairs.  (Out of Warranty 6 months ago).  

I am curious as to how to disassemble the printer to the point of being able to expose the lost paper and make sure the paper path is completely unobstructed.  I am good at repairing my own equipment but some guidance would help.

Any thoughts or suggestions would be helpful and appreciated.

Thanks,
