Original and Paper

If the same original is fed through the feeder repeatedly, the original may fold or become creased, and make 
feeding impossible. Limit repeated feeding to a maximum of 30 times (this number varies, depending on the 
type and quality of the original).
If the feeder rollers are dirty from scanning originals written in pencil, perform the feeder cleaning procedure. 
(See “Cleaning the Machine,” on p. 10‑2.)
Always smooth out any folds in your originals before placing them into the feeder.
Set the originals one by one if they are very thin (10 to 16 lb (37 to 52 g/m

2

)) or very thick (28 to 32 lb bond 

(105 to 128 g/m

2

)).

11" x 17" and LGL originals must be placed horizontally in the feeder.

Place your originals into the feeder as far as 
they will go.
If any dirt on the original scanning area is 
detected when the originals are placed in the 
feeder, the following screen appears. Even 
though streaks may appear on the copies, 
you can continue to scan your originals by 
pressing [Done].
It is recommended, however, that you open 
the feeder, clean the scanning area, and then 
close the feeder. The following screen will not 
appear once the scanning area is clean.
For instructions on cleaning the original 
scanning area, see “Cleaning the Machine,” on 
p. 10‑2.
