Worked good for a month, then started leaving a big black line down the middle of the page. Return/exchange process seems good though, so we'll see how the replacement cartridge works.

I need help. Installed the toner cartridge but the printer keeps asking for a replacement for the black one, after initialization and refuses to print out anything. the installation steps are straight forward though: shook the cartridge a few times, removed the protection slip, and inserted into the designated slot. thanks,
