摘要： A focus adjustment mechanism for adjusting a focus position of a printhead includes a rotatable pin that is rotatable around a pin axis. The rotatable pin includes a cam section located having a surface whose radial distance from the pin axis varies around its perimeter, and a gripping feature. An adjustment plate includes a gripping feature and is adapted to fit over and engage with the gripping feature of the rotatable pin such that the adjustment plate rotates together with the rotatable pin. A fastener fastens the adjustment plate to a support structure when the adjustment plate is positioned in a desired orientation. The printhead includes a frame feature which is pulled firmly against the cam section of the rotatable pin such that as the rotatable pin is rotated the frame feature rides on the surface of the cam section thereby adjusting the focus position of the printhead.

摘要： An image reading device includes an image sensor, a color reference portion, a test control portion, a standard distribution information storage portion, a type determination portion, and an abnormality notification portion. The image sensor is capable of outputting detection data of an amount of received light from each of a plurality of partial scanning areas, each at an individual channel. The test control portion is configured to cause the image sensor to operate under a plurality of test operation conditions different in resolution, when a document is not present. If a distribution state of the detection data at each channel acquired under each test operation condition does not match any of standard distribution information, the abnormality notification portion notifies an abnormality of another device related to the image sensor. The standard distribution information represents a standard distribution state of data at each channel under each test operation condition.

摘要： A scanning optical device includes a light source for emitting laser light, a rotatable polygonal mirror for deflecting the laser light emitted from the light source, a detecting portion for outputting a detection signal on the basis of incidence of the laser light deflected by the rotatable polygonal mirror on a light receiving surface, and an outputting portion for outputting a driving signal for driving the light source on the basis of output timing of the detection signal and an output period in which the detection signal is outputted. The laser light is emitted depending on an image signal inputted at timing based on output timing of the driving signal. When the output period is longer than a first period, the outputting portion outputs the driving signal on the basis of the output timing of the detection signal and a fixed second period.
