● Reduction of Throughput Based on Environment Temperature
Throughput is reduced according to the detected temperature of the Environment Sensor.
Detected temperature
Paper type
17 deg C or lower
Heavy paper 1
Heavy paper 2
13 deg C or lower
Plain paper 1
Thin paper 1
Thin paper 2
Plain paper 2
Note:
In MF8500 series, the thermistor does not detect environment temperature when it
exceeds a certain temperature. Thus, this control is executed only in MF8200 series.
● Reduction of Throughput by Feeding Small Size Paper
Note :
When paper size is specified by user, paper interval is increased from the 2nd sheet of
the job.
When a sensor detects that the paper size is small, paper interval is increased from 3rd
or 4th sheet of the job.
MF8500 Series
Based on the combination of detection result of the Pre-registration Detection Sensor and
detection result of paper length (L), paper interval extension time is determined according to
the table shown below.
Category
(1)
Plain paper (environment temperature is 18 deg C or lower),
heavy paper 1, heavy paper 2
(2)
Plain paper (environment temperature is higher than 18 deg C),

MF8200 Series
When small standard size paper other than A4 or LTR or custom paper size which paper
width is less than 195 mm is specified, throughput is reduced according to the number of
prints.
