摘要： An inkjet print device prints by reciprocally moving a carriage (15) in a main scan direction while controlling ink ejection from a print head (17) according to information on the position of the carriage (15) both in a forward movement and in a return movement. An encoder (22), a first U/D counter (29), a second U/D counter (30), a timer (31), and an interval timer (32) senses the position of the carriage (15). The encoder (22), the first U/D counter (29), and the timer (31) senses the speed of the carriage (15). A TBL memory (33) is used in determining a positional correction quantity at a sensed carriage speed from a positional correction quantity at a predetermined carriage speed. A head control section (26) controls ink ejection from the print head (17) based on the carriage position and the positional correction quantity.

摘要： An abnormality detecting method and an image processing method for an image processor is provided. The image processor can easily detect an abnormal rotation of a photosensitive drum without having a special detecting means but using an existing sensor, and keeps image data until a normal toner image is transferred and fine printing is carried out. The image processor forms a toner image corresponding to image data on a plurality of photosensitive drums, and detects the position of the toner image at a given part on a transfer object, to which given part the toner image formed on the photosensitive drum is transferred, to detect a rotation failure of the photosensitive drum. When a rotation failure is detected, the image processor keeps input image data without deleting even after the end of image formation.

摘要： An image density control device is for use in an image forming apparatus having an exposure lamp for emitting light to illuminate a document, a photoreceptor for receiving light reflected from the document to produce an electrostatic latent image, and a charger for charging the photoreceptor. The image density control device includes a detector for detecting the density of the document, a light emission amount controller responsive to the detector for holding an amount of light emitted from the exposure lamp at a predetermined fixed value when the document density lies in a predetermined range, and surface potential controller responsive to the detector means for controlling the charger to change the surface potential of the photoreceptor in accordance with a change in the document density when the document density lies in the predetermined range. The predetermined range may be a range defined by a minimum document density and a reference document density, or the one defined by another reference document density and a maximum document density. In the former case, the surface potential is increased in accordance with a decrease in the document density when the document density lies in the predetermined range. In the latter case, the surface potential is decreased in accordance with an increase in the document density when the document density lies in the predetermined range.

摘要： A document reader has a main conveying path, an auxiliary conveying path, a pickup roller, a first conveying roller, and a second conveying roller. The auxiliary conveying path runs between a first connection point and a second connection point on the main conveying path. The cylindrical surface of the first conveying roller is located partially on the main conveying path and partially on the auxiliary conveying path. While the first conveying roller is under the forward or reverse control, it rotates normally. The cylindrical surface of the second conveying roller is located partially on the main conveying path between the second connection point and a discharge position. A controller switches from the forward control selected during this mode to the reverse control, while a document being conveyed along the main conveying path is out of contact with the first conveying roller.

摘要： In a conveyance path made up of guide plates which guide a copy sheet to a transfer region between a photoreceptor and an opposing transfer device and a second guide plate for conveying the copy sheet to a fixing rollers, the guide plates and the fixing rollers including a pre-fixing guide, which all will be in contact with copy sheets, are grounded via a common resistor having a high resistance. An adjuster resistor is interposed in series between the common resistor and the guide plates positioned before transfer which are closer from the transfer region compared to the fixing rollers. When a copy sheet resides across the transfer region with both sides in contact with the guide plates and fixing rollers or with one side in contact, the total current that flows during a transfer operation is practically determined by the common resistor which has a high resistance. Accordingly, the flowing current can be limited within a certain range, thus it is possible to stabilize the transfer potential and hence to achieve a stabilized transfer operation.
