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.

sheets. These values are optimized before
*BCU
shipment. Do not change the values. Changing
*BCU
these values does not affect toner density on
paper sheets.
*BCU [0 to 1.500 / - / 0.01 mg/cm
*BCU
Displays the amount of each toner on the paper. A
*BCU
problem may have occurred in the printer engine if
*BCU
the value is high or low (i.e., if the difference
between SP3-905-1/2/3/4 and SP3-5/6/7/8 is
larger than ±0.03 mg/cm
Possible problems: Defective TD sensor, defective
ID sensor, toner near-end (if the value is lower
than the target), defective toner supply
