Humid Environments
To reduce paper curl in high temperature and
humidity environments, the fusing unit does idle
rotation before a job, if the customer enables this
function in the user mode.
Mode 1: No fusing idling, transfer roller voltage is
increased
Mode 2: Fusing unit rotates for 30 seconds before
a job, transfer roller voltage is increased.
Mode 3: Fusing unit rotates for 60 seconds before
a job, transfer roller voltage is increased.
Slide 139
Lab tests: Fusing idling mode 2 should be enough in most cases
