  • Patent number: 9141893
    Abstract: In the invention, an inclination amount of sensors is reflected in positional deviation correction patterns, and for correcting formation positions of images of various colors, the positional deviation correction patterns are formed on a conveying belt. The positional deviation correction patterns are detected by the sensors. A control unit calculates positional deviation correction amounts based on detection results of the positional deviation correction patterns. Based on the calculated positional deviation correction amounts, the control unit performs calculation for correcting the positional deviation correction patterns, and cancels the inclination amount reflected in the calculation results to obtain final positional deviation correction amounts. Skew correction is performed based on the final positional deviation correction amounts, and thus, the positional deviations are corrected.

  • Patent number: 9036198
    Abstract: An optical-writing control device calculates correction values for use in correcting a transfer position at which developing-agent images are to be transferred onto a sheet, and overlaying positions at which the developing-agent images are to be overlaid, based on a detection signal output from a sensor upon detection of a correction pattern for use in correcting the transfer position and a correction pattern for use in correcting the overlaying positions. A timing of detecting the pattern for use in correcting the overlaying positions is determined based on a correction value calculated based on the detection signal output upon detection of the pattern for use in correcting the transfer position. The pattern for use in correcting the transfer position is caused to have a width, in the main-scanning direction, that is wider than the width in the main-scanning direction of the pattern for use in correcting the overlaying positions.

The control section first uses the operational path by setting the first PCI/PCIe-bus expansion card to an active state. When a failure occurs in the operational path, the control section performs control such that communication recovery processing for the operational path is applied to the first HBA and further the second PCI/PCIe-bus expansion card of the second HBA is changed from a power saving state to which the second PCI/PCIe-bus expansion card has been first set, to an active state.
