The video shows the process of starting the printer, after that it knocks out an error (p02), it says that something is interfering with the carriage, but in fact there is nothing there, but I can’t understand what the problem is

Answer 1

It seems you have a torn off transparent strip with dark stripes, along which the carriage is oriented.

Without it, the printer does not detect the movement of the head and fixes its jamming.
