To improve image quality and reliability, the developer coating for both Cyan and Magenta 
has been changed to prevent toner drop in certain environmental conditions. To identify the 
“new type” developer, the product code 

has changed from AR-C17LD9 to AR-C19LD9 

accordingly. 

To maximise the effectiveness of AR-C19LD9 developer, follow the installation procedure 
below:- 

1.  Upgrade the PCU Firmware to the following versions (or higher):-. 

 

6.04d 

3.13

      Note: Field Test Firmware for AR-C160 (v3.11d) & AR-C270 (v3.05d) 

fully supports  

AR-C19LD9

. 

 
 

2.  Replace / Install the new type developer into the AR-DW1N developer units only. 
     (It is recommended that ALL 4 Developers are replaced at the same time).
