Question about HP LaserJet 2420dn Printer
Our office uses the HP 2420dn for several users. We recently replaced the toner cartridge and it is now printing shadows. We tried to run a cleaning and that made it worse by causing it to print pages dark gray. Please help!
Maybe the scan unit need to clean first you most sure that the toner cartridge is original and new then start clean th scan unit reflector
