I recently bought the 3880 and I have had occasional errors come up.
The error is 105c and it says to contact support for help.
I have been able to clear this by restarting the printer.
Does anyone know what this might be?
Sounds like an internal error code, meant to be given to tech support. I would suggest you simply do as asked and contact them. If purchased recently the printer is still under warranty, no point in trying to fix it yourself.
