摘要:
In a semiconductor laser optical system which uses a light source a semiconductor laser having different diverging points and divergence angles in orthogonal directions and in which the light beam from the light source is imaged on a scanned surface, only a spherical surface optical system is provided between the semiconductor laser and the scanned surface. The spherical surface optical system includes two partial optical systems, i.e. a first image forming optical system and a second image forming optical system as viewed from the light source side. By selecting the optical constant of one of the two image forming optical systems to a predetermined value, the peak power of the image forming spot on the scanned surface is maximized.

The disclosure describes a scanning optical system in which the scanning beam from a light source is deflected by a beam deflecting device to scan the scanning plane through a scanning beam focusing lens. The scanning optical system comprises a member disposed between the beam deflecting device and the focusing lens for reflecting a part of the scanning beam a plurality of times within the member so as to take up part of the beam as an information beam.

A quantizing unit, error detector, error diffusion matrix, and adder quantize a pixel of interest of an input image by an error diffusion method. A calculation unit and gain adjuster calculate a value to be added to the pixel of interest with reference to quantized pixels. The adder adds the calculated value to the pixel of interest. A control unit controls the calculation of the gain adjuster.

A halftone screen which is applicable to a low-resolution electrophotographic printer is created. Hence, dot-lattice points arranged in a predetermined region are displaced using rotation processing, the predetermined region is partitioned into polygons each of which surrounds the dot-lattice point. Then, a threshold matrix used to grow a halftone dot, which is surrounded by each polygon, in a direction of the displacement is generated.

A print cartridge includes a cartridge body having a lower portion and a vertical wall. A printhead is coupled with the lower portion of the cartridge body. A contact array including a plurality of contact areas is disposed on the vertical wall. The contact array is one of at least two contact arrays. Each contact array has a different pattern of contact area locations. A portion of the contact areas of each contact array are capable of providing identity information for the print cartridge.
