When trying to print I had a paper jam in my HP OfficeJet Pro 6987. I removed all the paper jammed that I could see. The printer screen displayed the error message Ox6100004a. I have tried some of the suggestions posted on the forum and on HP How to videos etc., and the suggestions haven't worked. The other problem is the ink cartridges will not move across to the other side when I tried moving them manually. It only moves a short distance.so I don't know if there is some paper underneath them.The store I bought it in was not servicing printers sat this time because of the COVID-19 virus pandemic..
