Review on Replacement 202X CF500A CF500X 202A by Gregory Plump

Began to change the cartridges as they were worn out, black was the first. Now I have a yellow one too. Everything started well, over time a line formed on the black, which gradually increased in size. Now it's one big stain on each side. Last night the printer gave the error "feed problem" and refused to print. Now, apart from the money lost with it, I can't print at all until I get a new toner. *Update* - The seller contacted me and confirmed that HP has released a firmware update that has disabled the cartridges. They have a workaround to fix this and fixed a bad black toner cartridge. In the end I'm impressed that they were concerned and contacted me to fix the issues.
