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.

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.
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.
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
