Canon PC - D 440

[karlmweru2020]

Hello everyone.
In front of this case a little more complicated once, I turn to the technical community.
I just received a Canon PC - D 440 who wrote nothing at all.
Whether copying or printing, the machine does not stop to present a white paper when you order a copy or printing.
I verified and deactivated the toner save mode, but it changed nothing.
I replaced the laser card, it changed nothing.
I replaced the cartridge, it has not changed but these cartridges have worked very well on another machine.
At the end of the effort, I do not know what to do for getting a solution to this problem.
Someone should have an idea please?
