Product: T520

We have this error. We have disconnected the Lan Cable and restarted the printer several times.  But problem persists even when printer is diconnedted from Network (no Wlan connection either).

Is the PCA Board broken. What can I do.

It's the USB firmware on PCA, that needs to be replaced, you can find them on eBay cheap.

Thank you.

 

Could I use a used one from another T520 too. I have one here.

I've ordered the one with the number CQ890-67105 because I've read it here in the forum before you posted. Is there a difference?

Your Picture shows ...111.

I know there are two versions of this model. I have the older A version with AX2cn... firmware.
