Purpose
To prevent fixing offset and deterioration of the Fixing Film by controlling temperature increase at a non paper feed area at
continuous printing of small-size paper (paper with the width-direction length of LTR landscape or less)
Startup conditions
When the temperature detected by the Sub Thermistor 1 (TH01_03) or Sub Thermistor 2 (TH01_01) has reached a specified
temperature or higher during printing.
Operation
The paper interval is increased to lower the temperature and adjust it slightly below the target printing temperature.

■ Down Sequence When Using Paper of Mixed Sizes and Types
Purpose
When feeding a sheet with a wider width than a preceding sheet during continuous printing, temperature at the non paper-feed
area of the Fixing Film increases, causing fixing offset and wrinkles upon feeding succeeding sheets. This down sequence controls
temperature increase at the non paper feed area of the Fixing Film.
