16.3.2.4.21 Fogging under low humidity environment
[ Verified by Canon Inc. ]
Field Remedy
Ever since DCON Ver.10.02 (DCON software which is to be installed simultaneously with System Ver.10.01),
the service mode described below has been newly added in order to ease fogging which might occur under low
humidity environment.
This service mode switches a bias of the lower auxiliary brush under low humidity environment from -800V to
-850V. If fogging occurs under low humidity environment, upgrade DCON to Ver.10.02 and later. The current
setting can be checked in the service mode below.
Service mode (level2) [COPIER> Option> BODY>LSUB-DWY/DWM/DWC]
