To all who offered various solutions to my problem with my computer. To begin, this is not the first time I've used said stock from my paper drawer. But it is the first time I've experienced problems... About the possibility of low 'toner' condition, know that the printer is a monochrome job... So just the one 'drum'. I may try the straight through approach, if nothing else works... Empty paper drawer and feed aux slot... But I shouldn't have to! I've done this before from the drawer with this stock!! But Sunday the printer refused to pick up the card stock...!
