[Error Code] CFB31 on KM 3050

[cbaker794]

Need help resolving a CFB31 on a KM 3050. I have reseated all connectors on OP panel and installen new RAM on main PCB. Still CFB31 after blue screen for about 5 minutes.

I've always been told by our Kyocera rep that CF codes are communication failure codes. Meaning something is just having problems talking to something else.

We see it alot with faxes and companies that do heavy printing and graphics printing. In your case I would check the connections on the Engine board that correspond to the Op Panel. Maybe strip it down to just base unit and doc feed and see what happens.

You might also want to try updating the firmware. The latest is 2.45A. It may not work but I'd try that before I started replacing parts.

Re: CFB31 on KM 3050

Did someone just work on the panel maybe? I've done this one myself:

"CFB31" error message after disassembling the panel to clean out foreign matter, then attempted to reload firmware. Tech connected (5) pin harness connector to YC9 instead of identical sized connector YC1. Connect (5) pin operation panel harness connector to YC1. Leave YC9 empty.

This one is less likely:

"CFB31" error after 2nd attempt to flash & ~5 min of "Program Loading". "Main CPU: ERROR" after flashing from V2.04C to V2.04D. Blue Screen of Death. Corrupted Main Eeprom. (also possible Op Panel Eeprom). Replace the Main Eeprom (part#: 302GR94201). Reflash if necessary.
