Heat error compensation
•
Low Heat Error
When this error occurs, it does not indicate an error but stores the present temperature and
supplies heat to the fuser. If the temperature increases after a a period of time, it goes back to
its normal state. However, if no temperature change is detected, an error will be flagged.
•
Over Heat Error
When this error occurs, it does not indicate an error but stores the present temperature and
cuts heat to the fuser. If the temperature decreases after a a period of time, it goes back to its
normal state. However, if no temperature change is detected, an error will be flagged.
Engine Interface Module Design
Engine Interface Module communicates with the main system in order to receive the command
from main system and to transmit the present engine status for the requested status. There are
two sub functions. One is a function to receive the command from the main system. The other is
a function that informs the main system of the current engine status for the requested item.
Engine Sensing and Unit Control Module Design
Engine Sensing & Unit Control Module consists of 4 sub-functions. The first function is an ADC
function that reads the ADC values of the temperature of the fixing unit. The second one is a fixing
unit control function. This function regulates the temperature of the fixing unit within a fixed range
to be set by the paper type and the number of pages to print out. The third one is a fan control
function that controls the fan unit. And the last one sets the flag that describes the present status
of each sensor.
