Description: 
In preparation for the launch of the AR-C270, the image quality specification of both  
AR-C160 & AR-C250 models have been enhanced to that of the new AR-C270. 
 
 
To identify these enhanced models, the product code has changed :-

 Image Quality 
 
To improve image quality on these models, we have introduced a new Developer Unit, new 
Developer and updated Engine Firmware. 
  
Developer Unit(s) 
 
The magnetic roller has been changed to a new type, with increased magnetic force. To 
identify the new type unit, the resistance value for each DV unit (DV check detection) has 
also been changed.  
 
The new type Developer Units (and developer) can be visibly identified by the “N” mark on 
the top of the unit as shown

Note: 
Do not install the new type Developer Unit(s) unless the Engine Firmware has been updated  
(refer to the firmware revision table within this bulletin). 
 
Failure to upgrade the engine firmware will result in a “DV Check CMYK” error. 
 
 
Developer 
 
The coating material and particle size for the new type developer has been changed from approx. 8um to 6um, 
to increase magnetic roller coverage and “tribo-electric” charge. 
 
To identify the new type Developer, the product code has changed.

Note:  
For AR-C150/250 models, the life of AR-C18LD1 is still 40k 
 
The “Old Type” Developer and Developer Unit will continue to be available for existing AR-C150,160 & 
250 models which have not been updated with this image quality enhancement modification. 
 
 
 
 
 
 
 
 
 
 
 
 
 
Engine Firmware  
 
Because the resistance value of each DV unit has changed, the engine firmware has been updated to 
automatically detect whether AR-DW1 or AR-DW1N are installed.  
 
Once the Developer Unit type has been detected, the correct toner correction “look up” table is referenced for 
either old or new type developer.  
 
The Developer Unit Type can be viewed using Test Simulation 44-43 (after DV cycle):- 
 
 
 
 
 
 
Type 0  = AR-DW1  
Type 1  = AR-DW1N

Please note that the enhancements are effective, only when new Developer, Developer Units 
and Engine Firmware have been installed/upgraded.
 
 
If the wrong combination is used (old type DV unit and new type Developer), it will not be 
effective and will cause copy quality problems (DV particles will attach to the drum).

All existing AR-C150, AR-C160 & AR-C250 models can be modified to the same image quality level as the new 
AR-C270 by installing new type Developer Units, Developer and Engine Firmware.  
 
Please refer to the following installation procedure:- 
 
Installation Procedure 
 
1. 
Enter Test Simulations 8 –01 and 8-02 and confirm that both DV Bias and Main Charge Grid Bias 
output voltages are set to their default values, as shown below.

 or within the “Colour Handy Guide 1”). 
 
3. 
Remove the existing Developer Units (AR-DW1) and install the New Type Units (AR-DW1N). 
 
4. 
Install the New Type Developer :-

5. 
Set the Developer Level (CMYK) using Test Simulation 25-02 (cycle twice). 
 
 
 
 
 
Note 
The stored DV level when using the New Type Developer will be lower  
(approx 20 points) than the previous levels, when using the Old Type Developer.  
 
6. 
Reset ALL Developer counters using Test Simulation 24-05.
