摘要： The image forming apparatus comprises a replaceable consumable, a determination unit for determining whether the consumable is non-genuine (S12), a first image-quality adjustment unit, and a second image-quality adjustment unit. When the determination unit determines that the consumable is non-genuine (YES in S12), the first image-quality adjustment unit performs an image-quality adjustment suitable for the non-genuine consumable (S13). When the determination unit determines that the consumable is genuine (No in S12), the second image-quality adjustment unit performs an image-quality adjustment suitable for the genuine consumable (S14).

摘要： In an image forming apparatus, a latent image is formed on a photoreceptor by an LED printing head based on image information. The latent image is developed into a toner image by a developing apparatus, to which a developing bias voltage is applied. The developing bias voltage is controlled according to a temperature of the LED printing head sensed by a temperature sensor so that a toner density of a toner image formed by the developing apparatus is appropriate.

摘要： An abnormality of a key component of an electrostatic image-recording machine is detected using a surface potentiometer originally installed in the machine for use in controlling the charging voltage of the photoreceptor drum. The detectable components are: main charger, transfer charger, discharge lamp, and developing roller. They are judged abnormal if the voltage of the drum surface is out of a normal range when they are functioned before an actual recording process (or during warming-up of the machine).

摘要： An image reading device is movable at a predetermined speed relative to a document in a lengthwise direction of the document so as to read a document image and includes a plurality of image sensors arranged in line in a widthwise direction of the document, each image sensor including an array of first to n-th photoelectric conversion elements arranged at the same interval in line, and scan means for causing the array of photoelectric conversion elements of the respective image sensors to scan in the order of first to n-th at a predetermined period. The array of photoelectric conversion elements of the respective image sensors is arranged in such a way that the first photoelectric conversion element slips relative to the n-th photoelectric conversion element a predetermined distance in the direction opposite to the relative movement direction of the image sensor, the predetermined distance being defined by the predetermined relative movement speed and the predetermined period.

摘要： An identifying system of a manuscript-reading device, receives signals from a pair of sensors disposed upstream of an optical system on the manuscript conveying path while conveying the manuscript for reading an image. In the event that the downstream side sensor remains OFF a predetermined time after the upstream side sensor turns ON or the downstream sensor remains ON a predetermined time after the upstream sensor turns OFF, an identifying system then identifies the presence of a jammed manuscript. Only when both sensors turn OFF together does the identifying system identify a state of release of the jammed manuscript.
