Platen Glass - Canon CLC5151 Reference Manual

NOTE
• If the top edge of the original is not aligned with the back edge of the platen glass (by the arrow in the
top left corner), your original may not be scanned correctly, depending on the copy mode that you have
set.
• A4 or A5 size originals of the following sizes can be placed either vertically or horizontally. However, the
scanning speed for horizontally placed originals is somewhat slower than vertically placed originals.
Place originals horizontally when scanning with a Preset Zoom, such as when enlarging an A4 original
onto A3 paper.
• Horizontally placed A4 and A5 originals are referred to as A4R and A5R.
• A3 originals must be placed horizontally.

Platen Glass

You should use the platen glass when copying bound originals (such as books and magazines),
heavy or lightweight originals, and transparencies. You should also place originals onto the
platen glass when you want to copy an A3 original with an image that extends all the way to the
edges without the periphery of the original being cut off. (See Chapter 1, "Introduction to the
Copying Functions," or Chapter 3, "Basic Copying Features," in the Copying and Mail Box
Guide, or Chapter 3, "Basic Scanning Features," in the Sending and Facsimile Guide.)
NOTE
The machine automatically detects the size of the following originals: A3, A4, A4R, and A5.
