MFP 1125 Rotate Paper function

The display screen reads "Rotate Paper."  I have to press select before the print job will begin.  Then it prints a blank sheet before printing the job.  When there is more than one page in a job I have to go through this process for each page.  What a bore.  This happens in all sorts of applications, even web printing, so I'm thinking it's a printer issue.  Besides, the printer is apparently programmed to display this message.  Surely there is a printer reason for it.

My manual is missing several pages in regard to troubleshooting.  After page 52 the next page is 67.  I looked up the online manual and can't find anything in the manual about a Rotate Paper process.  What the heck does that mean?
