How is the scanner connected? Also I want you to check some things that may or may not be affecting the situation. I am required to post any procedure as an Answer even if it is just a diagnostic test, so please ignore the Rate to Finish box and Reply to Expert after you have tried that.Restart the computer while holding the Command and R keys to boot to Recovery HD partition, when it boots select the Disk Utility and Continue. Then select Macintosh HD on the left and first Verify Disk on the right and if that is OK Repair Permissions. If Verify Disk is not OK try to Repair Disk.
Disk needed repairs. Done
Repair permissions needed. Done.
The scanner is connected by a USB cord to the computer.
I also have a samsung all-in-one scanner/printer connected.
Done but problem continues. it scanned two and crashed again. Originally the Epson never showed up in Print/scan preferences only the Samsung. It showed once and has disappeared again. How do I have the mac recognize the Epson as the default scanner but the Samsung as the printer.
The Epson just disappears from the System preferences Print/Scan and only the Samsung shows.
It seems only to work when I have removed the samsung Printer/scanner. But tis would be inconvenient.
This is the problem.
No reset printing system option available
Only samsung appears for adding. No sign of the Epson.
This really frustrating.
I got it.
But only the Samsung printer appears. There is no pane for scanners and no opportunity to add the Epson.
I rebooted and the print/Scan pane reappeared.But still no Epson.
I agree this Epson has to be defective.
Will return to the Apple store.
Thanks for your patience.
