摘要： The image forming apparatus includes: a paper feed unit; a print unit; a registration roller; a sheet leading end sensor provided downstream, in a transport direction of the recording paper, of the registration roller; a time measuring unit for measuring a time from a start point of transportation of the recording paper by the registration roller to a point of detection of the leading end of the recording paper by the sheet leading end sensor; a memory unit for storing a reference image forming time and a reference time; a print control unit; and an arithmetic unit for obtaining a difference between the reference time and the time detected by the time measuring unit. The print control unit adjusts the length of the image forming period in accordance with the adjusted image forming time determined based on the difference obtained by the arithmetic unit and the reference image forming time.

摘要： Mechanism unit(s) functioning as automatic-feed cassette(s) and mechanism unit(s) functioning as manual-feed tray(s) together form a single integral module, constituting a hybrid paper supply module. In such constitution, paper transport path(s) may be formed between or among first guide member(s) provided at automatic-feed cassette mechanism unit(s) and second guide member(s) provided at manual-feed mechanism unit(s), and manual-feed mechanism unit(s) may be pulled outward and to side(s) of apparatus(es) so as to cause paper transport path(s) to be opened up to the exterior, facilitating removal of jammed paper. Furthermore, given such constitution, a plurality of hybrid paper supply modules may be stacked together to constitute a paper supply mechanism. Manual-feed tray(s) with which manual-feed mechanism unit(s) of respective hybrid paper supply module(s) is or are provided may be collapsible so as to permit extension and/or retraction. This will permit manual-feed tray(s) to be able to accommodate a plurality of types of recording media.

摘要： A pair of drive conveyer rollers are provided for a platen that guides recording media. The follower conveyer roller is supported by a roller support plate which is coupled at its side with a lever so that the rotation of this lever is able to press the platen downward. When the paired drive conveyer rollers hold recording paper between them, the follower conveyer roller moves upward, which causes the roller support plate to rotate. This rotational force is transmitted to the lever so that the platen is pressed down to thereby adjust the gap between the printer head and the platen appropriately.
