摘要： A separator includes a front edge disposed opposite an outer circumferential surface of an endless belt. The front edge contacts and separates a recording medium from the endless belt. A separation plate mounts the front edge. A contact plate projects from the separation plate in an axial direction of the endless belt and contacts a belt holder that supports the endless belt. A bracket projects from the separation plate in a direction orthogonal to the direction in which the contact plate projects from the separation plate. The bracket includes a notch that engages the belt holder. The contact plate contacting the belt holder and the notch of the bracket engaging the belt holder produce an interval between the front edge of the separator and the outer circumferential surface of the endless belt.

摘要： A fixing device includes a support supporting a nip formation assembly that presses against an opposed rotary body via an endless belt to form a fixing nip between the endless belt and the opposed rotary body. The support includes a base contacting the nip formation assembly. An upstream projection projects from the base in a pressurization direction of the opposed rotary body at a position on the base corresponding to or upstream from an upstream edge of the fixing nip in a recording medium conveyance direction. A downstream projection projects from the base in the pressurization direction of the opposed rotary body at a position on the base corresponding to or downstream from a downstream edge of the fixing nip in the recording medium conveyance direction. The downstream projection is spaced apart from the upstream projection in the recording medium conveyance direction.

摘要： A disk drive unit and an error recovery method for the disk drive unit which can reduce processing time for ERP in resetting, thereby shortening response time to the reset is described. A normal error recovery procedure is executed if there is no reset request when a write error occurs, but if there is a reset request pending, a data record in which a write error occurs is registered as a defective position (e.g. sector) and an alternate (spare) position is assigned to accelerate the time when the drive can respond to the reset instruction. Data records with alternate positions assigned as a part of the reset activity are specially marked so that alternate position assignment can be undone as soon as is appropriate, for example, when the record is next read or written.
