Follow these steps to change a tray’s paper size setting.

Note:

- The paper size setting cannot be changed when the machine has

stopped  temporarily  due  to  running  out  of  paper  or  a  misfeed,  or
during interrupt copying.

- During printing (even in copy mode), the paper size setting cannot

be changed.

- Do not load paper that is a different size than the paper size set-

ting. Copying will not be possible.

1) Hold  down  the  [PAPER]  key  for  more  than  5  seconds  to  set  the

selected paper size.

The  currently  selected  paper  feed  location  indicator  will  blink  and
the corresponding paper  size  (which is currently  set) indicator will
display.

2) If the machine has two or more paper trays, use the [TRAY] key to

select the paper tray for which you wish to change the paper size
setting. Each time the [TRAY] key is pressed, a paper tray will be
indicated with a blinking paper feed location indicator.
