HP 2055 will print 3 pages & receives a jam in the cartridge area

[cleyba4]

Hello, I have an HP 2055dn that will print 3 pages & receive a jam in the cartridge area. I have replaced all the maintenance parts with new parts including transfer roller. The fuser has 9500 pages so far. New pickup rollers & pad. It’s very clean. I’ve replaced the drawer as well with no change. I have a heavily used HP 2035 that I also replaced all the pick up rollers & transfer roller & it’s doing the same thing. I have taken the sides off to watch the paper travel through & it just stops printing after picking up 2 - 3 pages. Once in a while it’ll print 5 pages & stop. There’s 1 page in the output, one page going into the fuser & one page half in the drawer & half inside the printer & stops at the transfer roller. I have replace the transfer rollers on both & still no change. I’m a printer tech with 10 years experience but this issue has me stumped. Any suggestions would be great. Thank you

Try printing from Tray1, if it works then you have a sticky solenoid for paper pickup from Tray2

Thank you. I’ll clean the solenoid switch & try again. Thank you for the quick reply.

I checked the pick up roller solenoid for tray 2. I found a sticky substance in between the contacts & it was sticking. I cleaned the contacts with alcohol & carefully put a small piece of black tape on one side of the solenoid contact to prevent a future issue. By the way, tray 1 worked continuously with no jams which lead to the sticky solenoid. 
 Thank you for the quick reply & a pin point answer.
