摘要:
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.

A cartridge chip 106 for use with an imaging cartridge installed in an imaging device, the cartridge chip comprising a memory element 106 storing imaging cartridge data, and a controller 104 for controlling the operation of the cartridge chip and determining if the imaging device is a first type of imaging device or a second type of imaging device, the controller for operating the cartridge chip in a first mode of operation if the imaging device is the first type of imaging device, the controller for operating the cartridge chip in a second mode of operation if the imaging device is the second type of imaging device.
摘要:
In an image forming apparatus, a replaceable process unit which holds a photosensitive body and a device to form at least one image can be held in a holding section. The image forming apparatus counts an amount of use of the process unit and stores a count value in a storage section. When the image forming apparatus performs a printing operation, the apparatus determines whether a mode selectively set by a mode setting section is a first mode (ST2) in which a printing operation stops when the count value reaches a predetermined value or a second mode (ST8) in which the printing operation does not stop when the count value reaches the predetermined value.
摘要:
The present invention is an ink container for use in an ink jet printing system. The printing system has a printhead under control of printing system electronics and an ink container receiving station for providing ink to the printhead. The replaceable ink container includes a plurality of container interfacing features positioned on the ink container to engage corresponding ink container receiving station interfacing features. The ink container interfacing features are disposed and arranged to allow a plurality of different sizes of the ink container to be installed at a particular location of the receiving station. The ink container also includes an information storage device that provides information indicative of a volume of ink contained in said ink container.

A process cartridge (14) detachably mountable to a main assembly (15) of an image forming apparatus includes an image bearing member; and storing means (18) for storing information which a user inputs using input means (16) of the main assembly of the image forming apparatus, or an external device connected to the main assembly of the image forming apparatus. The information can be compressed before being written in the storing means. The information can also be represented by an identification code and inputted via a guidance software. In case of trouble data indicative of said trouble can be read from the storing means.
摘要:
The present invention provides a process cartridge (13) detachably mountable to an image forming apparatus, comprising an electrophotographic photosensitive member, process means acting on the electrophotographic photosensitive member, and a memory means (71) for transmitting information regarding at least the process means to the image forming apparatus. Wherein the memory means (71) is attached to a front end face (14a) of the process cartridge in an inserting direction of the process cartridge into the image forming apparatus to be connected to a connector member (45) of the image forming apparatus.
