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 (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. The value (-3) means that the printer knows that
there remains capacity for at least one unit.
Additional information:
LaserJet 4500 is capable of determining when the face-down
bin goes full, but not the level of that bin. LaserJet 4500
is not capable of determining whether the face-up bin
is full.
LaserJet 4500 will report a value of 0 when the face-down
bin is full and -3 when the face down bin is not full.
