A:Answer The answer to both questions is yes. The sheet feeder for the scanner can be widened to just under 12 inches, so 11 x 17 documents can be scanned if an 11-inch side is faced into the machine. The height of the feeder opening is about an inch, so a stack of anything (11 x 17, 8.5 x 11, or anything else) that high can be accommodated.
