Laser scanning device and image forming apparatus including the same

A laser scanning device includes a light source, a deflection portion, an image forming lens, and a light source control portion. The light source emits a light beam. The deflection portion causes the light beam emitted from the light source to scan a scanned surface by deflecting the light beam at a predetermined deflection angle. The image forming lens condenses the deflected light beam on the scanned surface, and causes the light beam to be scanned on the scanned surface in a scanning direction at an equal speed. The light source control portion controls the light source to irradiate the light beam to at least one section area among a plurality of section areas sectioned from each other in the scanning direction on the scanned surface, at a plurality of irradiation timings determined based on a position of the at least one section area in the scanning direction.

A lens-mirror array includes a second optical element arranged adjacent to a first optical element in a main-scan direction. The first optical element has an incident surface, a first reflection surface, and an exit surface. The incident surface is shaped to transmit and focus a light incident on the incident surface. The first reflection surface has positive optical power and is configured to reflect and focus the light entering through the incident surface. The exit surface outputs the light reflected by the first reflection surface. The second optical element includes a second reflection surface. A travel blocking portion is provided between the first reflection surface and the second reflection surface. A reflectance reduction layer is provided in the travel blocking portion to set light reflectance in the travel blocking portion to be lower than that of the first reflection surface.

In-situ printhead focus adjustment

A method is described for adjusting the focus position of a linear printhead in a digital printing system. A line image is printed including a plurality of variable linewidth lines at different cross-track positions. A digital image capture system is used to capture an image of the printed line image, and a data processing system is used to automatically analyze the captured image to determine linewidth parameters representing linewidths of the plurality of lines. Linewidth progression functions are determined for the lines responsive to the determined linewidths, wherein the linewidth progression functions represent the linewidth parameters as a function of position. The linewidth progression functions are analyzed to determine defocus characteristics of the linear printhead, which are used to adjust the focus position of the linear printhead.
