I just replace my toner in my HP Laserjet 4050 but it will not print anything, there is no error , even printing a test page, only blank paper comes out. Is this a fuser problem?
You could have a bad cartridge or did you forget to pull the toner tab? Review the troubleshooting steps in this manual: HP Laserjet 4000 & 4050 Service Manual
