Question about HP LaserJet 2420 Printer
Have replaced black cartridge and attention light still flashes. The only way to get it to print is to open the top cover and close it. The printer then checks itself and retrieves data, then prints. Have to open the top plate every time to print.
Try reset the printer. Turn off powerswitch, press gobutton, turn on powerswitch while pressing gobutton. hold approx 15sec and release the button. The printer will reboot. Clean the cartridge contacts and HV pins in printer.
