What software did you update?
It is very difficult to offer troubleshooting suggestions when the "os version" you are using is unknown as each os has their own troubleshooting solutions.
Thanks for your help.
I am going to try to update drivers first and then call Epson tomorrow if updating drivers does not work.
I have updated my Mac pro to OS 10.6.8 and it is a Epson Stylus Color 740 Jet Printer.
So far I have tried this from this link.
I ran disk utility and as soon as I try the driver update I'll let you know.
