Abstract: An image forming apparatus includes a controller configured to perform an acquisition processing of acquiring a preceding command, a preparation processing, and a printing processing. In a case where the controller determines that a performance condition of the printing processing is satisfied, the controller is configured to perform the preparation processing in response to acquisition of the preceding command, and the printing processing in accordance with a print instruction. In a case where the controller determines that the performance condition is not satisfied, the controller is configured not to perform the preparation processing in response to the acquisition of the preceding command. In a case where the controller determines that the performance condition is satisfied after the controller determines that the performance condition is not satisfied, the controller is configured to perform the preparation processing and the printing processing in accordance with the print instruction.

Abstract: An image forming apparatus includes a frame, a drum cartridge mountable to the frame, and including a photosensitive drum and a drum memory in which drum identification information identifying the drum cartridge is stored, and a control unit including a main body memory in which the drum identification information is to be stored. The control unit reads out the drum identification information from the drum memory, determines whether the drum identification information read out from the drum memory coincides with the drum identification information stored in the main body memory, and enables to execute resister pitch measuring processing of measuring variations in printing pitch due to the photosensitive drum. In a case where it is determined that the drum identification information read out from drum memory coincides with the drum identification information stored in the main body memory, the control unit does not execute the resister pitch measuring processing.

Abstract: A washer having such a thickness t that a value (L3?(L1+L2+t)) obtained by subtracting the sum of a first distance L1 in an axial direction between a leading end face of a friction member and a face of a lockup piston, a second distance L2 in the axial direction between a shell-side abutting face of a pump shell and a face of an outside extended portion of an output hub, and the thickness t in the axial direction of the washer, from a third distance L3 in the axial direction between an opposed face of a front cover and a cover-side abutting face of a tubular portion, is in a predetermined range larger than zero, is selected and placed between the lockup piston and the outside extended portion of the output hub.

Abstract: A copying machine is configured to execute a first scanning process to scan an image on an original sheet and generate image data, which is stored in a storage of the copying machine and an external processing device, a printing process to print the image of the original sheet, a second scanning process to release an image data storing area of the storage, and store the image data in the storage and the external processing device, a transmission process to release the image data storing area of the storage, and transmit the image data from the external processing device to the storage, and a detection process to detect whether a free capacity of the storage becomes less than a particular value.

Abstract: A printing apparatus includes: a receiving section which receives a print data from the external apparatus; a storage section in which the print data received by the receiving section is stored; an input section which receives from a user a print instruction for printing based on the print data stored in the storage section; a print section which performs the printing of the image on the recording medium based on the print data stored in the storage section in a case that the input section receives the print instruction from the user; and a controller which controls the storage section and which calculates and sets for the print data stored in the storage section a storage time-period within which the print data is storable in the storage section.

Abstract: Image data is stored in a RAM, and when recording media are fed from a paper feed tray for a time interval longer than a predetermined time interval, a CPU causes an image forming section to execute a correction process.
