摘要： A method of controlling a fuser unit of an image-forming apparatus such as a laser printer, in a warming-up stage, so that excess mechanical and electrostatic stresses are not imposed on the process elements. The method includes the steps of: starting the energization of a heater of a heat roller substantially at the same time as the commencement of an initialization process of mechanical and electrostatic conditions of the apparatus while rotating the heat roller and a backup roller together; stopping the rotation of the rollers after the initialization process has been completed; monitoring a surface temperature of the heat roller for a first predetermined period after the completion of the initialization; and if the surface temperature has reached a set value within the first predetermined period, determining that the fuser unit is ready for operation, and conversely, if the set value has not reached within the first predetermined period, carrying out an additional warming-up process of rotating the heat roller and the back-up roller again until the set value is reached, unless a second predetermined period has expired subsequent to the expiration of the first predetermined period.

摘要： An image forming apparatus includes a plurality of image bearing members bearing latent images, image forming units for forming the latent images on the image bearing members, developing units for developing the latent images on the image bearing members, a transport belt for transporting a transfer member on which images of different colors developed by the developing units are successively transferred as the transfer member is transported, and image pickup elements, arranged obliquely to a main scan direction of the image forming units and located on a downstream of a most downstream one of the image bearing members along a direction in which the transport belt transports the transfer member. The image pickup elements detect as image information transmitted or reflected light quantity distributions of regions which include marks transferred on the transport belt from the image bearing members. The image forming apparatus further includes a correction unit for detecting correction quantities from error quantities of marks transferred from the image bearing members other than a reference image bearing member with respect to a reference mark transferred from the reference image bearing member based on the image information detected by the image pickup elements, and correcting positions of the latent images formed on the image bearing members other than the reference image bearing member depending on the correction quantities.

摘要： A printing apparatus used in a computer system selects either one of a plurality of paper feed cassettes and prints image data onto a cut sheet supplied from the selected cassette. Paper sensors are individually attached at predetermined positions which are located just after a plurality of paper feed cassettes at the same distance. The paper conveying times from the attaching positions of the paper sensors to a print start request position have been preset. When the cassette is switched during the printing operation, the predetermined paper feed timing time is changed. When switching from the cassette at a near position to the cassette at a remote position, the paper feed timing time is set to a short time and the paper feeding operation from the cassette on the switching side is instructed. When switching from the cassette at a remote position to the cassette at a near position, the predetermined paper feed timing time is set to a long time and the paper feeding operation from the cassette on the switching side is instructed.
