Details 
Main body control-related 
If the mounted USB memory is pulled out during restart after simulation with the restart 
function is released, the LCD screen display may become unstable depending on the 
timing. This glitch has been corrected. 
Main body control-related 
The system clock would go back to approximately 5 years, 5 months and 8 days previous 
for a maximum of 1 minute if an operation is made on the home screen, the system 
settings screen, or the preview screen after turning on the power and then operation is 
made on the home screen, the system settings screen after at least 6 hours. This glitch 
has been corrected. 
Main body control-related 
The machine may hang up if the power is turned on, on the panel under shut-off status, 
and then the power is turned off immediately. This glitch has been corrected. 
4 Simulation-related 
SIM22-25, SIM24-25, or SUM24-35 may be unable to be executed because destination 
information is sometimes mistakenly read depending on timing when the power is turned 
on. This glitch has been corrected. (Power off/on can recover this glitch.) 
5 Simulation-related 
The retransmission history may not be cleared in Sim66-10 (FAX memory image data 
clear). This glitch has been corrected. 
6 Simulation-related 
Items Sim24-30 “Initializing administrator password” and Sim24-31 “Initializing service 
password” with security kit installed were deleted. 
7 Simulation-related 
Transition from external authentication mode to simulation has been made possible. 
8 Simulation-related 
Indication of the cumulative number of developer/drum rotations has been added to 
Sim22-13. 
9 Simulation-related 
Entering simulation mode was disabled for 5 minutes if a problem with U2-00/U2-11/U2-
12/U2-22/U2-23/U2-30/U2-50/U2-24/U2-10/U2-05(E7-03) occurs in external 
authentication. This glitch has been corrected. 
10 Simulation-related 
Upon a jam during colour copy operation using SPF, an error occurs if system setting and 
colour calibration are performed after releasing the jam. This glitch has been corrected. 
11 Simulation-related 
Enable setting for fusing cleaning mode (self-printing) in the system setting menu has 
been added to the following Sim:
