4. Main Fuser Assembly end of life detection
(a) End of life detection
The life of the Main Fuser Assembly is determined by the print
image density being fused. Life expectancy is determined from
the accumulated dispense time and the number of images
(image count) being fused. If either reaches a predetermined
value, an end of life warning or a life exceeded error is detected.
(b) Dispense time
The dispense time is the accumulated hours that the Dispense
Motor has been in use. This data can be used to calculate toner
consumption (PDCD or ADC). The conditions for the Main Fuser
Assembly end of life detection are defined in the following table:
Table 2-23. MAIN FUSER ASSEMBLY Counter (sec.)
Main Fuser Assembly end of life warning
(Maintenance-call error xxxx)
Main Fuser Assembly life - exceeded
(Service-call error 0003)
(c) Image count
A toner image for one color is counted as one image. The image
count accumulates the number of images being formed.

NOTE:One printing in the YMCBk mode consist of 4 images (4
counts); one printing in the B/W mode is 1 image (1 count).
