Question about Kyocera FS-3900DN Laser Printer
Error code 7410 indicates that the drum unit is not installed correctly. This is usually caused by dirty contacts or a faulty drum unit chip. First remove the toner and developer unit, then the waste toner bottle. Unlock and remove the drum unit by depressing the catch that sits behind the waste toner bottle and pulling the unit out to the L/H side. Be very careful not to scratch the drum and avoid strong light as it is easily damaged. Clean up all contacts and refit in reverse order. Hope this helps, if not you may need to buy a new drum unit.
