The maximum capacity of the input sub-unit in input
sub-unit capacity units (PrtCapacityUnitTC). There is no
convention associated with the media itself so this value
reflects claimed capacity. If this input 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:
This is
specified assuming 20 pound paper for the paper trays.
The tray 3 object does not exist when that option
is NOT installed.
