Description: The remaining capacity of the possible output sub-unit capacity in output sub-unit capacity units (CapacityUnit) 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 Contol 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: The values reported for output sub-unit 1 (face-down, top bin) will be either (-3) (ie, unknown) if it is not full or (0) if it is full.

Output sub-unit 2 (face-up, left side bin) does not have any sensing, so it will always report unknown (-2).

The first output sub-unit (3) of the HCO reports either (-3) (ie, unknown) if it is not full or (0) if it is full.

In mailbox mode, the HCO sub-units (4-8) will report (250) when empty, (125) when there's room for <250 sheets and (0) when full. The STAPLER sub-unit (9) will report (-3) when not full and (0) when full.

In stacker and job separator modes all bins are treated as a single output bin so sub-unit 4 will report (1250) when all bins are empty. A value of (0) is reported when the topmost bin is full (stacker mode) or when all bins are full (separator mode).

When the stacker or separator has started filling, the value reported is based on the number of bins that are empty, partially filled and full. A percentage is calculated based on the status of each bin. Each full bin counts 1, each not empty/not full bin counts 0.5 and each empty bin counts 0. The result is mapped to an estimate of the remaining capacity as follows (percent full is included here for completeness, since that is how the HCO reports it to the printer): 0.0 0 (100%) 0.5 200 ( 90%) 1.0 300 ( 85%) 1.5 400 ( 80%) 2.0 500 ( 75%) 2.5 700 ( 65%) 3.0 800 ( 60%) 3.5 900 ( 55%) 4.0 1000 ( 50%) 4.5 1200 ( 40%) 5.0 1300 ( 35%) 5.5 1400 ( 30%) 6.0 1500 ( 25%) 6.5 1700 ( 15%) 7.0 1800 ( 10%) 7.5 1900 ( 5%) 8.0 2000 ( 0%)

Note: Due to HCO mechanism limitations, the value reported may not always be accurate (the bin status is detected only when the media delivery head is moved to or past a physical bin). Also, for stacker mode a bin is considered full as long as any bin above it is not empty. Default values assume all sub-units are empty and the HCO is in mailbox mode.
