CHAPTER 6 FIXING SYSTEM
In down sequence, 40 cpm or 35 cpm mode is initiated to suit the surface
temperature of the upper fixing roller.
Normal sequence will be initiated when the surface temperature of the upper fixing
roller reaches a specific level (Table 6-104); however, once copying has been
suspended, WMUP sequence will be used until the surface temperature of the upper
fixing roller reaches 195°C (as in auto start mode).
If any of the foregoing levels of surface temperature is detected during copying
operation, the machine starts WMUP sequence while indicating the remaining number
of copies on the control panel. When the Copy Start key is pressed as in auto start or
during STBY, the remaining number of copies are made.
