Epson 4500 Printer – Not Connected to Macintosh Fix

Another computer printer problem in the world order. This time an individual was no longer able to use their Epson 4500 Printer. The original initial question is quoted verbatim below.

All of a sudden my Epson 4500 printer/scanner says it’s not connected to my Macintosh (operating system Mojave 10.14.3). It has just happened on a frantic work day. What to do?

It is definitely connected.

This is a common problem that occurs on both Apple Macintosh computers and Microsoft Windows based computers. This individual could no longer scan using the automatic document feeder. Also, this type of false positive, so to speak, problem is NOT mutually exclusive to just Epson brand printers.

This type of problem can occur with any brand of printer. When they tried to scan they also received that dreaded not connected error. This individual tried to power off both their Apple Macintosh computer and Epson 4500 printer as well as disconnecting their printer from their Apple Macintosh computer.
