Kyocera Ecosys M3040idn Error F21F

[The Guru]

Hi all

Has anybody ever come across this error? Cant find it in any manuals or in Service World.

Thanks for looking

Looking in other service manuals for the larger machines I see that it references
"Abnormality detecting in an image-processing part"

with the following suggestions

1. Check contact of a DDR memory and perform an operation
check.
2. Initialize HDD and perform an operation check.
(FULL of U024) *
3. Carry out U021 Main backup initialization and perform an operation
check.
4. Exchange a Main board and perform an operation check.
5. Exchange HDD and perform an operation check.
*
6. Get USBLOG and contact service headquarters.
* Only HDD standard model

Thanks for the reply

It is only a small machine basically a 30 ppm printer with a scanner slung on top so no HDD or memory card, updated Firmware and did U021. Its intermittent so it looks like main control PWB to me.

Thanks again for your help
