摘要:
A toner fill plug for a toner cartridge within an image forming device. The cartridge includes a toner reservoir having a port through which toner is input. The plug is sized to fit within the port and prevent toner leakage. The plug includes a reflector which aligns with an adjacently-positioned toner level sensor for determining the amount of toner remaining within the reservoir. The plug is removable to allow the user to refill the reservoir with new toner.
摘要:
A toner cartridge included with an image forming device when initially sent to a user. The cartridge has a limited toner capacity. The user is able to print with the small capacity cartridge upon initially receiving the image forming device. Once the toner is exhausted, a second large capacity cartridge having a greater toner capacity can replace the small capacity cartridge. The small capacity cartridge and the large capacity cartridge are constructed in a similar shape to be mounted in the same manner within the image forming device.
摘要:
A gear unit comprising a shaft and a gear each having a first axial section and a second axial section. The first axial section features the gear having external teeth with an internal surface that corresponds to an external surface of the shaft. The second axial section includes features in the shaft and gear that engage together. Methods of using the gear unit including positioned the gear on the shaft, and rotating the gear relative to the shaft to engage the gear with the shaft.
摘要:
An image-fixing device for use in an electrophotographic process which includes a wiping member (61,62,64,67) in contact with the back-up roller of the fusing portion of the device is disclosed. This wiping member eliminates moisture condensation on the back-up roller (51). This acts to eliminate stalls and paper jams without requiring major reformulation of the compositions of the fuser belt or back-up roll or the structure of the printer.
摘要:
A ceramic heater for use in an electrophotographic printing process, particularly for use with a belt fuser to fix toner images, is disclosed. This heater is preferably made from a ceramic material substrate and contains a heat-generating resistor and electrical connections for said resistor on one face of the substrate and a temperature-detecting element for detecting and controlling the temperature of said heater, together with electrical connections for said detecting element, on the opposing face of the substrate. Belt fusers, which incorporate these heaters, are also disclosed.
