Alex Sherwin

Did you try to reinstall the printer driver?

Customer Replay

yes, but it wouldn't install. maybe could try again now

Alex Sherwin

If you could then please try it, in the meantime I will check what else can be done.
Please check the fax connection:
Check for phone line connection issues that might cause fax receiving to fail. Confirm the fax cords are in the correct ports: The phone line should be connected to the 1-LINE port and the answering machine, if used, should be connected to the 2-EXT port on the back of the printer.
If you have any other questions, I'll be happy to help you out!
