Operating System: Mac OS X 10.11 El Capitan

I am trying to copy using printer only.  When I touch 'Start Black' (or 'Start Color')I get the message: 'Incorrect Paper. Copy does not support Custom.  Load a supported size of paper in the tray.  Touch "?" to view the supporten paper sizes.  Note: To use the paper currently loaded in the tray anyway, touch "Continue" or touch "Cancel" to cancel. 

When I touch Continue the printer displays a message Copying page 1/1... and then ejects a blank page and displays a messsage: Paper Size Mismatch The paper size detected (Letter(8.5x11 in.)) by the printer does not match the paper size selected (Custom) for the print job.  When I touch OK it displays Copying page 1/1... And just waits indefinitely.

When I go to Copy Settings "Paper Size and Type" shows Custom, Plain P...  When I touch ">" to change this setting I get the message "Incorrect Paper Copy does not support Custom.  Load a supported size of paper in the tray to continue.

How do I change the paper size from Custom back to Letter, please I am desperately trying an am not able to do it.

I tried reset factory settings and just shutting the printer down and turning it back on again.  The custom size in 'Copy' remains and I am not able to copy anything. I have updated the printer software to the most recent version.
