Description: The maximum capacity of this output sub-unit in output sub-unit capacity units (PrtCapacityUnitTC). There is no convention associated with the media itself so this value essentially reflects claimed capacity. If this output sub-unit can reliably sense this value, the value is sensed by the printer and may not be changed by management requests; otherwise, the value may be written (by a Remote Control Panel or a Management Application). The value (-1) means other and specifically indicates that the sub-unit places no restrictions on this parameter. The value (-2) means unknown. Additional information: LaserJet 4500 cannot sense the amount of paper in its standard output bin; however, the face-up bin can hold 50 sheets of 20lb. paper, and the face-down bin can hold 250 sheets.
