My canon lbp622c/623c is printing blank pages. I have cleaned, replaced ALL cartridges, updated software, etc and it is still printing blank pages. It goes through the entire cycle and spits out a blank page. It also recently doesn't pull from the tray (no paper error) so I have to manually scroll to the full tray of paper. Any suggestions besides buying a new printer? It is only 2 years old and I just spent a mint buying new cartridges.
