摘要： An image forming apparatus includes a plurality of image forming portions, an intermediate transfer belt, a primary transfer member, a secondary transfer roller, a counter roller, and a charge eliminating device. The counter roller is pressed against the secondary transfer roller via an intermediate transfer belt to thereby form a secondary transfer nip portion. The charge eliminating device includes a charge eliminating needle that is disposed with an end part thereof pointing to a downstream side in a conveyance direction of the recording medium, and that is grounded, and a charge eliminating needle protection cover that has a guide surface that is opposed to the recording medium having passed through the secondary transfer nip portion. The guide surface is formed of a conductive material having a resistance value of 106Ω or lower, and is in a floating state.

摘要： A printer includes a controller that operates an actuator of a transfer assist blade (TAB) mechanism with reference to an actuator profile. The actuator profile identifies an actuator waveform and a plurality of pulse trains for the actuator waveform. The actuator profile and the data associated with it are developed with reference to the drive train for the TAB mechanism. The actuator profiles enable the TAB mechanism drive train to achieve optimal operation over a wide range of media types, substrate speeds, pitch modes, and other print job parameters.

摘要： An image forming apparatus includes: a cover configured to be pivotal between a closed position and an open position to open an opening portion through which an intermediate transfer unit is removable, wherein when the cover is moved from an intermediate position to the open position, a secondary transfer unit is changed by using a self-weight of the secondary transfer unit from a first relative position to a second relative position, and wherein when the cover is located in the open position and the intermediate transfer unit is supported in a first position by a guiding portion, a secondary transfer unit interferes with the intermediate transfer unit if located in the first relative position, but does not interfere with the intermediate transfer unit if located in the second relative position.

摘要： An image forming apparatus includes a first detection portion at a first guide provided in an image forming unit and a second detection portion at a second guide provided in a unit drawable to the exterior of the image forming apparatus. Since there are many parts in this apparatus, an error in the relative positions of the first and the second detection portions is large. The image forming apparatus includes a lock member configured to lock the unit to an image forming apparatus main body, and a pressure member configured to, when the unit is locked to the image forming apparatus main body, press the first guide and the second guide to each other. As a result, adjustment of the relative positions of the first and the second detection portions is not required at the time of replacement of the unit or the detection portions.

摘要： This is a baffle used in a transfer station of an electrophotographic marking system. The baffle has a series of air passages that, when these passages are opened, they apply pressure to a sheet of paper and push it upward against a belt or drum surface of a photoreceptor or photoconductor. The toner imaged photoreceptor then transfers the image to the paper that is in contact with it. From the transfer station, the paper with the transferred image is then moved to the fuser station where the image is fused to the paper.The baffle with air passages does not scratch the photoconductor surface as do the prior art systems. Also, the baffle has a much longer useful life than the more costly lift finger transfer blades previously used.A controller senses when a sheet enters the transfer station, senses the paper size, then activates a number of air passages to match the paper size.

摘要： Systems and methods are described that facilitate automatically and uniformly depositing a marking material on transfer assist blade (TAB) petals to improve TAB pressure profile accuracy. A TAB liftoff timing value is adjusted in non-volatile memory (NVM) to delay TAB liftoff beyond a trailing edge of a page on which an oversized (in the process direction) image being printed. Toner deposited on a photoreceptor belt beyond the trailing edge of the page is picked up by the TAB petals once the trailing edge of the page has passed the TAB. The TAB is then disengaged and re-engaged against a backside of a next page, where the TAB petals deposit the uniformly acquired toner to generate the TAB pressure profile.

摘要： In a fixing device for thermally fixing a developer image transferred onto a recording sheet, a nip plate is disposed on an inner surface of a tubular flexible fusing member which is flexibly deformable in such a manner that permits the fusing member to slide along the nip plate, and configured to be heated by a heating element disposed inside the fusing member. The fusing member is nipped between the nip plate and a backup member to form a nip portion between the fusing member and the backup member. The nip plate is bent to form a recessed portion which opens on the inner surface of the fusing member and holds a lubricant.
