My problem was that I was trying to print from a PDF file. I found out that the file was legal size and that the setting for the printer to "choose paper source by PDF size" was checked. I unchecked it so that it would print on letter size paper. Hope this helps

Ya, I had that same problem too; I was printing something that was over printing margins, and then i had the message "supply rec. paper......" on the lcd screen. I ended up fixing the problem by clearing/canceling all the documents i was printing on my computer, and clearing/canceling all the documents saved inside the MEMORY OF THE PRINTER (note the green light with the "memory, in use" which means it's probably still trying to print the document that's too big, so it wont print anything else). (<--- not sure if that was your problem, but it was mine)

Anyways, to clear the memory inside the printer, i pressed the "status monitor" button located to the left of the "B&W start" button, and then i scrolled over to "print status, select job to cancel" and canceled all jobs, and then once i canceled all jobs, the alarm disappeared, and it was fixed XD
