Delta Vt Threshold
021 This SP is the threshold for toner end. Delta Vt: Vt-Vtref
When both this SP and SP3-101-026 occur at same time, toner end is
determined.
Displays the total delta Vt (Vt-Vtref) value for each color.These are calculated

024 Delta Vt Sum: C
025 Delta Vt Sum: Y
026 Delta Vt Sum Threshold
027 Gamma Threshold: Coefficient
Displays the consumed toner amount calculated with the pixel count for each
028-031
color.
