Hi all I am working on a ir6570 that is getting the e121 code, don't know the sub code. Any clues or helpful hints? This is another tech's machine and I don' see this model very frequently. Thanks in advance.

This is from documentation:
E121 There is a controller cooling fan error.
0001 Even though the controller cooling fan has been
turned on, the controller cooling fan stop signal has
been detected for 5 sec or more.
- Check the connector for any fault in connection.
- Replace the fan. -
It was the controller fan kind of. I pulled the fan out and cleaned about a pound (seemed like it) of dust out of it. Cleaned the filter, really dirty, re-connected connector on controller board(J108) fired it up and it works. Thanks for sending me in the right direction.Comment
