● Processing after failure detection
If the Main Motor is in driving state when Fixing Assembly failure is detected, rotation of the
motor is maintained for 300 msec after the machine moves in Fixing Assembly failure state.
Then, drive systems (Main Motor system, Laser/Scanner system, high voltage system, and
fixing system) are stopped immediately and the machine moves in failure state.
If the Main Motor is not in driving state, drive systems are stopped immediately and the
machine moves in failure state.

Other Functions

■ Throughput Down Control

The machine reduces throughput by increasing the paper interval to prevent the temperature
rise at the edge of the Fixing Heater (H1) during continuous printing of small size paper (up
to 271 mm long and 189.6 mm wide), and of the Delivery Assembly during large volume
continuous printing.
Lengthening the paper interval allows the Fixing Heater to cool enough to prevent the
temperature rise of the Fixing Assembly roller edge and Delivery Assembly.
● Throughput Down Sequence
If the temperature continues to rise after continuous printing of 20 sheets with "plain paper" or
"plain paper L" fixing mode at 400 dpi resolution, throughput is reduced for the remainder of
the job.
Productivity (throughput down): 18 ppm -> 10 ppm

● Throughput Down at Initial Rotation
The time for initial rotation is extended according to the fixing mode. The time is also
extended when smeared image control mode 2 or paper wrinkle/curl prevention mode is
specified.
