MISFEED REMOVAL
When the misfeed (
) indicator blinks or 
 blinks in the display, the unit will 
stop because of a misfeed. If a misfeed occurs when using the SPF/RSPF, a number 
may appear in the display after a minus sign. This indicates the number of the 
originals that must be returned to the original feeder tray after a misfeed. Return the 
required number of originals. Then this number will disappear when copying is 
resumed or the clear (
) key is pressed. When the SPF/RSPF misfeeds an 
original sheet, the unit will stop and the SPF/RSPF misfeed (
) indicator will blink, 
while the misfeed (
) indicator will remain off. For a misfeed of originals in the SPF/
RSPF, see "E: Misfeed in the SPF/RSPF" (p.66).

(p.10).

Check the misfeed location. Remove the misfed paper 
following the instructions for each location in the illustration 
below. If 
 
blinks in the display, proceed to "A: Misfeed in the 
paper feed area" (p.64).
If the unit is turned on with the lower side cover open, the misfeed (
indicator will blink. In this case, close the lower side cover. The misfeed 
(
) indicator will go out.
If paper is misfed here, proceed to "A:  
Misfeed in the paper feed area
". (p.64)
If paper is misfed here, proceed 
to "D: Misfeed in the lower 
paper feed area
". (p.66)
If paper is misfed here, proceed to "B:  
Misfeed in the fusing area
". (p.64)
If the misfed paper is seen from

in the transport area
". (p.65)
