Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
What was the paper type of the original document in the last successful copy operation (that appears to have 'caused' more or less, this problem) ?
What is the exact and full text of the ADF error message now, please?
How old is the Epson printer in question?
I need this information, to judge as to what might be going on with the printer and its error, please. Thanks.
