Kyocera fs-3900dn showing 7410:0024216 error code what do I do

Sounds like a Engine firmware failure. The clue is the low page count (the 00007).
You will need to upgrade your firmware and contact your local Kyocera sales comany to get a patch to correct the missing serial number and MAC address.

The message is indicating that you do not havea real Kyocera toner installed in the machine.

Hi,
This problem is caused by a poor contact in the fuser connector terminals.
Check both sides of the connection (in the printer and fuser unit) In most cases we will find small pieces of paper inside printer connector causing poor contact between printer and fuser unit connector.
Hope i was of any help. If i was, please rate me.
Thank you.

Right click on the printer icon and choose properties. Your emulations are listed there.

0150 - Engine PWB EEPROM error. Detecting engine PWB EEPROM communication error.

Solutions:
1. Switch the printer OFF; unplug the power cable; wait 20 seconds; plug in the power cable; switch the power ON, If the error comes back follow the next solutions:
2. Update / Burn the latest firmware version. You may need to call a Kyocera Service Provider because you need a CF card (compact flash memory card) and the FIRMWARE.
3. Replace the Engine PWB (a board) - again you have to call a Kyocera Service Provider.

did the error came on after replacing tonercartridge ?

open the door at the left and push on the drum till you hear click, problem should be solved afterwards.

This is a laser problem. The polygon motor probably got jammed usually it needs to be cleaned and oiled or the motor has ceased.

It needs a firmware update, very common, it would most likely be under warranty, if not post email so I can give you the firmware update required and I will instruct you on how to upload it to your quality printer.
