I have a HP 1100 laserjet printer. At work on Friday a sticky label got stuck in the printers cartridge. This caused the printer to jam up and it started to make a clicking noise. I replaced the cartridge but now it won't print out properly. Two vertical white lines appear all the way through the document. I have tried all the simple stuff such as checking settings and have tried two new cartridges. Also I have striped the printer down but can't see anything obvious wrong. How do laserjet printers work, what could need cleaned or replaced.
Cheers
Jeremy
