摘要： A uniform velocity and/or time of flight profile across the jet streams of a multinozzle aspirated ink jet printer is maintained by a closed loop servo system. The servo system includes a drop charge sensor which senses the time of flight of charge droplets in the streams and generates a controlled signal. The signal is utilized by a controller means to generate controlled voltages. The voltages are used to adjust the velocity of a motor/blower apparatus which supplies air to the aspirated ink jet printer.

摘要： Cartridge (1) contains a brush charger (32) and printer (40) contains a charge roller (30). Upon installation of the cartridge a top shutter (7) is moved downward and the charge roller is moved by a pivoted arm (44) through the opening left by the shutter to contact a photoconductor drum (24) in the cartridge. In operation the roller functions after charging by the brush at a potential to control the final charge on a photoconductor prior to xerographic imaging. The precharging by the brush greatly reduces deterioration of the charge roller, permitting long machine life with the accurate and uniform operation of a charge roller.

摘要： In a multinozzle ink jet printing system, a closed loop servo system drives the drop generator so that the distance between the streams at which ink droplets are detached is maintained at an optimum range. One or more sensors are positioned downstream from the multinozzle plate of the ink jet printing system. The sensors sense the flight time of ink droplets and output signals which are developed into a variable voltage for controlling the drop generator.

摘要： A method of printing with an electrophotographic machine includes providing a first optical sensor for sensing a start-of-scan position of a laser beam produced by a scanning laser printhead and transmitting a first position signal indicative thereof A second optical sensor senses an end-of-scan position of the laser beam produced by the scanning laser printhead and transmits a second position signal indicative thereof A temperature of the scanning laser printhead is measured with a temperature sensing device. A plurality of positions of each of the first optical sensor and the second optical sensor are empirically determined at each of a plurality of values of the temperature of the scanning laser beam printhead. The modulation or position of the laser beam produced by the scanning laser printhead is adjusted based upon the first position signal, the second position signal, the measured temperature of the laser printhead, and the empirically determined positions of the first optical sensor and the second optical sensor and the second optical sensor. A single optical sensor and a single thermal sensor constitute the minimum hardware embodiment to perform print line position correction based upon stored empirical relationship.

摘要： An image-fixing device for use in an electrophotographic process which includes an electrode (discharge member) on the exit side of a fuser mechanism is disclosed. This mechanism eliminates toner offset without requiring reformulation of the fuser or pressure rollers or restructuring of the fuser, and without compromising the release properties of those rollers. The preferred electrode has a saw-tooth configuration and is placed close to, but not contacting, the pressure roller and the back side of the printed page. A voltage, typically from about 200 to about 1,000 volts is applied to that electrode; the voltage has a polarity which is opposite the charge of the toner on the printed page.

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

摘要： A method and apparatus to clear the accumulation of toner particles from a doctor element by periodically reversing a bias field between a doctor element and a developer member. The developer member may be biased to a first electrical potential while the doctor element may be biased to a second electrical potential. The second electrical potential may be higher than the first electrical potential. The doctor element and the developer member may be biased from a single voltage supply and a voltage dividing circuit. A bias reversing circuit may cause the second electrical potential to fall, at least temporarily, below that of the first electrical potential when power from the voltage supply is removed. The bias reversing circuit may also cause the first electrical potential to fall with a longer time constant than that of the second electrical potential when power from the voltage supply is removed.
