Title: Toner cartridge with hopper exit agitator
Inventor: CAMPBELL ALAN STIRLING
IPC: G03G15/08
Filed: 1998-02-13
Granted: 1999-09-21
Abstract: A toner cartridge (1) has a cylindrical toner hopper (61) with a rear wall (61a) defining an output opening well above the lower part of the hopper. A paddle (63) is rotated in the hopper. The exit surface (61a) declines downward to form a chamber for the toner adder roller (45) and developer roller (43). This configuration discourages toner from returning to the hopper after it has been electrically charged. To improve movement of toner past the opening an agitator bar (65) extends across the cartridge near the exit surface. The bar is pivoted at both ends and has a portion (65a) which extends into the path of the paddle. As the paddle rotates, it moves the agitator upward until the curved paths of the two members reach separation, at which time the bar drops by gravity. The bar jars toner loose and eliminates jams of toner. The flat surface of the bar, when it has been moved up, partially blocks the exit opening, which desirably limits toner flow.

Title: Method and apparatus for automatically determining the style printhead installed in a laser printer
Inventor: CLARKE CYRUS BRADFORD
IPC: B41J2/44
Filed: 1998-04-01
Granted: 2000-10-01
Abstract: A laser printer is provided having an automatic printhead identification system for use in a family of laser printers that are compatible with more than one model of printhead. For example, a single laser printer model can be made so that two different printheads can be successfully used, so long as the printer system knows which laser printhead has actually been installed. To detect which printhead has been installed, the printer operating system provides a reference clock signal having a pre-determined frequency, which dictates the rotational speed of the motor. Once the motor has achieved a ""lock"" operational speed, the printer measures the scan rate of the faceted mirror by detecting the time interval between pulses of the ""HSYNC"" signal. The HSYNC signal is sent to a ""divide-by-n counter"" circuit which divides the pulse frequency of the HSYNC signal, thereby increasing the time interval (by a factor of ""n"") that must be sensed by the system to determine which printhead is in fact installed. So long as the HSYNC ""lock"" frequency is different between the various models of printheads that are compatible with a particular model laser printer, the principles of the invention can be used without adding any extra hardware sensors, signals, or memory addresses and detecting codes.
