HP LaserJet 2420d Printer

A black horizontal line appears on all printed documents. Have used laser printer cleaners but to no avail. Is there a printer repair kit for this problem?
Could be the toner cartridge. Do a half test. Put a sheet of paper on the manual feeder and perform a self test page from the printer menu. When the back edge enters the printer, open the toner door quickly to stop the printing. Now remove the toner and look at the unfused image below. If the defect is present it is the toner cartridge and if not then the fuser is the probable cause and will have to be replaced.
