Main unit control 

Downloading of Device Cloning data fails if IE 10 is used. This problem has been 
corrected. 

28 

Main unit control 

There were some cases where the color of the output result changed in the process of 
continuous printing.    This problem has been corrected.

 

29 

Main unit control 

Currently the fuser pressure release operation is performed in 90 seconds after the 
machine enters the ready state but the start time of fuser pressure release has been 
changed to 120 minutes to enhance the life of the pressure spring. 
*It is confirmed that no flat spot (unrecoverable deformation of the roller) is caused by 
this countermeasure.

Main unit control 

Fusing trouble is caused because of the adjustment to lower the fusing temperature 
when the detection temperature of the machine reaches 27-degree or higher.    For the 
countermeasure of this issue, the modification has been made not to perform this 
adjustment. 
 
Note) If the fusing temperature setting value of SIM43-1 is changed due to the action 
from T/R No. CCE-1229, please be sure to return the value to the default (0) for both 
Plain Paper/Recycled paper.

Main unit control 

Though the setting range of the preheat mode is 1 – 60 minutes on Administrator 
Settings List, it is printed as 1 – 240 minutes. This problem has been corrected. 

32 

Main unit control 

Forced tray switch does not function if Printer job is performed in parallel vendor mode. 
This problem has been corrected. 

33 

Main unit control 

Occasionally, toner quantity jumps to 5%. This problem has been corrected. 

34 

Main unit control 

For the paper whose width is less than A4R in NN/NH/HH environment, the secondary 
transfer current is reduced and also Soft SW which enables to set PTC to the low-output 
is added.   
 
SIM55-1: 
27-6 Default: 0(OFF): 1 (ON: when printing in B/W) 
27-7 Default: 0(OFF): 1 (ON: when printing in Color)

 

35 

Main unit control 

A new Simulation mode has been developed to conform to new standard of "Blue Angel" 
(eco-label for Germany). The check box for Auto power shut off mode is not displayed 
when this mode is enabled that machine enters Auto power shut off mode at any time. 
 
Sim26-50 POWER SHUT-OFF SET 
 
While checkbox is not displayed: The machine is under factory default condition for 
EUROPE/UK. 
While displayed: The machine is under factory default condition for those other than 
EUROPE/UK.
