13.8.4 Detection of abnormal status
When an abnormal condition is detected inside the ADU, a symbol corresponding to the condition is
shown on the copier's control panel. The following kinds of abnormal status may be encountered:
(1) Abnormal statuses which can be cleared without pulling out/pushing in the ADU:
• Paper misfeeding which occurs while paper is being fed from the stack section.
(2) Abnormal statuses which can be cleared by pulling out/pushing in the ADU:
• Paper misfeeding in the paper stack section.
(3) Abnormal statuses which can be cleared only by turning OFF/ON the copier's power switch:
• When the side guides or end guide cannot be initialized to their correct positions.
[A] Paper misfeeding
(1)Paper misfeeding during duplex copying:
While paper is fed from the ADU, if the copier's P-STP-SW is not turned ON within about 1 sec.
after FEDCLT CLT1
ADU paper feeding, and a paper misfeed symbol is displayed. This condition can be cleared by
opening/closing the copier's side cover.
(2)Paper misfeeding during paper stacking:
During paper stacking, if the ADU's JAM-SW SA4 is not turned ON within about 3 sec. after the
copier's EXIT-SW was turned ON/OFF, it is judged that paper misfeeding has occurred inside the
ADU. To clear this condition, pull out the ADU, remove the misfed sheet, then push in the ADU. (If
necessary, open/close the copier's front cover.)
[B] Abnormal statuses at power ON
(1)Paper remaining in the stack section at power ON:
If a sheet of paper is left in the stack section when the power is turned ON, a symbol indicating that
paper is still there is displayed on the copier's control panel when the duplexing mode is selected.
This mode cannot be started until the paper is removed.
(2)Misfed paper remaining inside the ADU when the power is turned ON:
If a misfed sheet of paper remains on the ADU's paper path when the power is turned ON, the ADU
misfeed symbol is shown. To clear this condition, pull out the ADU, remove the misfed sheet and
then push in the ADU. (If necessary, open/close the copier's front cover.)
[C] "Serviceman Call" errors
(1)The paper side guides and end guide cannot be initialized :
During the initialization of the SID-MOT DM3 and END-MOT DM2
