Constantly saying cartridges jammed

[NikitaG]

Printer keeps saying paper jam even when there isn’t one so I have to open up machine take out inside then put back then it works, whilst doing this the cartridge moved trapping my thumb, I eventually got my thumb out but now it says that the cartridges r jammed and not installed correctly and nothing I’m trying is working. They close back and forth fine, there’s nothing jamming them and they are installed correctly. Can anyone help please?
