Hi, how are you? Please if you could help me I am new to the forum, I have a problem with a 1023 canon which does not feed toner, it takes a long time to load and in the end it gives a low or absent toner error, I have checked the development unit and it is found empty is to say that it fails to feed the toner, this happened then to clean the developer unit since it presented clear copies as well as the prints ..

Good afternoon friend, if you undo the toner unit, you must place toner in the part where the magnetic roller goes fill that part manually mind

you disassembled your development unit ... and you cleaned it .. the detail is that you put it wrong you have to disassemble again and assemble it step by step ... even if you put toner directly on the hopper .. it will continue to do the same thing .. because the machine is not detecting the toner cartridge .. luck

Thanks for your reply friend, I will try again to see how it goes!
