This is a Fan issue you have 2 of them one on the front right side and one on the left. if you remove both covers see which one is not working
Now if their are both working then you will need to replace the ECU (Engine Control Unit).

I've attached a link that shows you how to remove the covers off the 2420 it's a pdf file .
And the Left side cover will need to be removed to access the other fan.

Hi
Problem either fuser faulty or dc controller card faulty first check for faulty fuser & after then dc controller fuse of fuser.
Thanks

power on your printer, after you see processing data the second time, press cancel.
Everytime I have seen this error is because the user tries to print a PDF file that is corrupt.
This has worked for me in the past.

Good luck!

It's a communication or hardware error.

It's best if you update your firmware. Get the files from the link below...

Try to reinstall your software, if it is show the error again replaced the memory and then try to power on the printer.
