3. Temperature control for the both ends of the fuser roller
During a continuous printing, the temperature of the both ends of the fuser roller (areas where the
paper does not pass on) tends to be higher than that of the other areas (where the paper passes
on). For this reason, the temperature of the both ends of the fuser roller is detected by the fuser
roller front thermistor. If this thermistor has detected an abnormal temperature (270°C or above), the
IH coil is preferentially turned off regardless of the temperature of the areas where the paper passes
on.
4. Temperature control at Energy Saving Mode
This equipment has the following two types of temperature control for saving energy and returns to
ready status to perform printing in each mode upon printing request.
The period of time from the printing request to this mode can be set in "Setting Mode (08)" or by an
administrator.
Administrator setting procedure:
[USER FUNCTIONS] button → [ADMIN] (input of administrator's password) → [GENERAL] →
[ENERGY SAVER]
Auto Power Save Mode (Setting Mode (08-205)):
When the printing is not performed in a specified period of time (default setting: 15 min.) after the
previous printing is completed, the equipment enters to Auto Power Save Mode to turn OFF the IH
coil.
Auto Shut Off Mode (Setting Mode (08-206)):
When the printing is not performed in a specified period of time (default setting: 90 min).
* after the equipment entered to Auto Power Save Mode, the equipment then enters to Auto Shut
Off Mode to turn OFF the IH coil.
