Cartrigde load error

Hello

I just receive my Zeepro 3D. I start to load my first cartridge without
problem but the second one can not take in the plastic filament (I
followed advises to load correctly the cartridge, pull out a little bit
the filament to ensure smooth loading and push
it back). The small rotating piece is running but cannot engaged the
plastic filament to the system.

Anyone else has a solution ?

Thank
Xavier

If that doesn’t work, perhaps you can use the first cartridge to print this:
