Cartridge spring thing

I disassembled my 2300DN to clean the sticky solenoids. After putting it back together I seem to have created another problem. The cartridge isn't detected at all and I think I know why. See these pictures:





The red circle is where the items in the 2nd image came from. Most of them, at least. I noticed that there was a tiny spring that fell out when disassembling and I didn't know where it came from. After reassembling it gave me the cartridge error. I know for certain where the large spring and the plastic thing goes, and I'm pretty sure that metal bit goes inside the plastic thing, but I don't know if the smaller spring goes inside the plastic thing along with it.

The small spring can fit inside the plastic thing, but I'm not sure if it goes in first and then the metal bit, or vice versa. I'm not sure it even goes in there at all.

What I noticed though is that the metal bit is just loose on the inside of the plastic thing and it doesn't poke out firmly. It just rattles on the inside. That's why I think that smaller spring is necessary but I can't confirm.

What I do know is that if I take out that entire metal housing circled in the first picture and I press in with screwdriver, it hits this spring-loaded button on the cartridge and it recognizes it.

I seem to have figured out the problem and I’ll leave this here for future reference. Turns out, the assembly of items in the photo I took was missing a small metal cap that goes into the plastic thing after the metal bit and small spring. That gives e small spring the force it needs to poke out the plastic part. I didn’t realize it was a part of the way it works until I saw it laying in my floor and wondered what it was.


Now I’ve just got to figure out why tray 2 is jamming...

Need details on the jam. Like how far does the paper go. Good job on figuring out the spring.
