[Process Contr.] Process Control
TD Adj. Times *BCU [1 to 3 / 3 / 1/step] 3125 006
Limits the number of auto toner density adjustments. The auto toner density
adjustment consists of three steps: detecting the development gamma, supplying or
consuming toner, and detecting the development gamma again. When these three
steps are all complete, it means a single auto toner density adjustment is complete.
Temperature *BCU [ 0 to 200 / 60 / 1°C /step] 3125 007
Adjusts the fusing temperature threshold for process control execution when the
main switch is turned on.
Pic Vb Max *BCU [ 600 to 800 / 680 / 10 V /step] 3125 008
Adjusts the development bias upper limit.
Pic Vb Min *BCU [ 200 to 400 / 300 / 10 V /step] 3125 009
Adjusts the development bias lower limit.
3126 [Forced SelfChk] Forced Self-check
3126 001 Forced SelfChk Performs a forced process control self-check.
3126 002 Forced TD Adj. Performs a forced auto toner density adjustment.

3903
Adjusts the M/A (Mass per Area, mg/cm
2
) value used during the process control
self-check. Adjusting this changes the development bias. This causes the solid ID to
increase or decrease. If developer capability causes an ID problem, toner density
needs to be adjusted with SP3-120-1 to 4, depending on the color.
