prtmarkersupplieslevel OBJECT-TYPE
SYNTAX INTEGER
MAX-ACCESS read-only
STATUS current
DESCRIPTION
"The current level if this supply is a container; the
remaining space if this supply is a receptacle. If this
supply container/receptacle can reliably sense this
value, the value is reported by the printer and is
read-only; 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. A value of (-3) means that the
printer knows that there is some supply/remaining space,
respectively.
Refer to Standard Printer MIB for more details.
Additional information:
LaserJet 4050 Series will have a new toner-measuring feature that
utilizes the GRIN ASIC's ability to detect the amount of pixels
that have been placed on a single page. This Pixel-Counting
Gas Gauge should be able to calculate toner levels within 10%.
Because textual printing and graphics printing utilize different
pixel usage, accuracy for the counting algorithms have been
biased toward textual printing. Heavy graphics printing will
cause the cartridge to appear to be emptier than it really is.
Over time however, statistical averaging values that are kept in
NVRAM will help make the gauge more accurate according to
individual customer usage models. The new values will vary
between 0 and 4600 depending on how much toner has been
calculated to have been used."
