Multiple function encoder wheel for cartridges utilized in an electrophotographic output device

TLDR
In this article, the authors describe an electrophotographic machine with an encoder wheel and a coded wheel reader, which is configured for indicating the amount of toner remaining in the sump.
Abstract
Disclosed is a cartridge (30) having an encoder wheel (31) thereon for encoding EP supply cartridge characteristic information for an electrophotographic machine, the cartridge comprising a sump (33) for carrying an initial amount of toner (35). A shaft (32) is mounted for rotation in said sump, and an agitator or paddle (34) is mounted thereon in such a manner that when the shaft (32) rotates, the paddle (34) rotates into, through and out of engagement with toner (35) carried by the sump. A single encoder wheel (31) is mounted on the shaft (32), external of the sump (33), the encoder wheel positioned for proximate mating coaction with a coded wheel reader when the cartridge (30) is mounted in position in the electrophotographic machine. A variable torque flexible coupling connects the drive means of the electrophotographic machine to the shaft (32) to effect rotation thereof. The encoder wheel (31) is configured for indicating, in conjunction with said coded wheel reader, a component of resistance to paddle (34) movement through the portion of said sump (33) having toner (35) therein to give an indication of the amount of toner remaining in said sump. Other portions of the wheel (31), in a portion thereof which confronts the reader during a substantially constant velocity of rotation thereof, carry additional characteristic information of the cartridge (30) to permit proper operation of the machine as well as increased efficiency of operation thereof.

Method and apparatus for measuring and displaying a toner tally for a printer

TL;DR: The Toner Tally as discussed by the authors uses a combination hardware/software counter to count the number of "active" pels of each page for a print job, which can be used to judge the amount of toner used for one print job and compare that to the amount used for a second print job.

Printer toner usage indicator with image weighted calculation

TL;DR: In this paper, an improved system for more accurately estimating consumption of toner imaging material in a digital xerographic printer in relation to a count of the digital pixels generating the various images being printed, where the frequency rates of the switching between print and non-print pixels are analyzed to provide weighting factors corresponding to different types of image being printed which affect the consumption of imaging material by the printer.
