Description: The remaining capacity of the possible output sub-unit capacity in output sub-unit capacity units (PrtCapacityUnitTC) of this output sub-unit. If this output sub-unit can reliably sense this value, the value is sensed by the printer and may not be modified by management requests; otherwise, the value may be written. The value (-1) means other and specifically indicates that the sub-unit places no restrictions on this parameter. The value (-2) means unknown. The value (-3) means that the printer knows that there remains capacity for at least one unit. Refer to Internet Draft Printer MIB, expiring Sept. 1997 for more details. Additional information: LaserJet Series 4000 is capable of determining when the face-down bin goes full, but not the level of that bin. LaserJet Series 4000 is not capable of determining whether the face-up bin is full. RemainingCapacity capabilities of the stapler/stacker, as well as unplanned HCO devices, are currently T.B.D. LaserJet Series 4000 will report a value of 0 when the face-down bin is full and -3 when the face down bin is not full.
