PIXMA TS6420a cartridge issue, support Code 7700

[Dscheible]

I’m getting support code 7700, when I open the top of my printer, my ink cartridges are not sliding over automatically, but I can manually pull them over. How can I fix the automatic sliding? I imagine that is linked to my support code.
