My LaserJet Pro 400 color m451dn printer suddenly had a problem with REGISTRATION. The colors on the left look great, but as you look to the right of the page, everything is misaligned badly.
I've run the calibration and done cleaning many times. Tried different cartridges. Went online to the HP Web Services and typed in my printer's IP address and tried some more things. Nothing is working.
Can someone help?
