Hp4250 was making almost blank pages. I installed a new (generic) unit and it produced prints like the photo attached.
I took the new unit out and put it in another 4250 and it printed fine.
Took cartridge from yet another good 4250 , put it in original printer but it still makes these weird patterns.
What could this be ? All I did was replace cartridge
