Thanks for the response. In reply:
1. No other function in the program works -- same communications error message.
2. I have attempted to disable the Status Monitor, but cannot locate the option to disable it in Printing Preferences. Based on searches for how to disable it, the selection should appear where the Driver Update button is located in the screen shot below. I've downloaded and installed the current driver from the Epson site. Suggestions as to where that disable function may have moved? Anything else that might be interfering with communication between the adjustment program and the printer? There is no option to disable within the Status Monitor dialogue box, either. Thanks, Jeff
