Symptom Corrected
Suffix
1st mass production firmware -
1. Copy speed returns to normal after performing forced process control in SP mode, even while
low speed mode is enabled.
2. Paper remaining in the duplex unit cannot be exited by forced feed.
3. SC990 is displayed when the front door is opened/closed following jam recovery.
4. "Waste toner bottle full" display cannot be cleared.
5. SC670 occurs or the panel display freezes when the development bias is set to its maximum
value.
6. Staple jam occurs at second set with Mixed Sizes/Stapling.
7. Changed the step interval for SP1907 from 100 to 10.
8. Modified for use with Copy Connector Kit.
A
1. Lower toner bottle cap motor remains ON, even after power Off/On following motor output
check with the upper and lower bottles removed.
2. Display for remaining sheets in left tandem tray remains at full, even when transferring the
sheets to the right tray.
3. V-jam alert for the Bypass tray (jam at feed sensor) is not cleared after the paper is removed
and the tray slide is opened/closed, but is cleared when the mainframe right door is
opened/closed.
4. Modified for use with the EB-105EX controller (EFI).
B
A misfeed of three sheets or more sometimes triggers Jam Code 53 when LT paper is fed LEF
from the 1st tandem tray. The pick-off solenoid On timing (feed timing of the next sheet) has been
delayed to prevent the jam.
Note:
1. Jam code 53: Feed sensor for the 1st tandem tray detects the presence of paper after the
predetermined interval has expired.
2. This symptom only occurs under the conditions specified above, i.e. it does not occur with any
other tray or paper size.
