  • Patent number: 8346154
    Abstract: A conveyance control mechanism for a printer including an image forming unit forming an image on a sheet being conveyed on a conveyance route, includes a curl detector configured to detect a curl of the sheet conveyed on the conveyance route, in an upstream of the image forming unit on the conveyance route. The conveyance route controller may drive and stop the conveyance route differently depending on whether the curl detector detects a curl at either a front end or at a position other than the front end. When the curl detector detects a curl of the sheet, an image forming route where the image forming unit performs an image formation may be separated and retreated from the conveyance route and the sheet being conveyed may be discharged onto the retreated image forming route.

  • Publication number: 20120161388
    Abstract: A printing device includes: a registration roller that once stops a transferred sheet and then feeds the transferred sheet toward an inkjet head unit; a sheet feed system that transfers and feeds a sheet to the registration roller; a sheet refeed system that, during both-side printing, reverses a one-side printed sheet and transfers the one-side printed sheet to the registration roller; and a controller that, during both-side printing, controls the registration roller so as to feed a sheet, which is fed by the sheet feed system and the sheet refeed system, toward the inkjet head unit in accordance with a predetermined print schedule. The controller controls the sheet feed system in accordance with the print schedule so that a speed when a sheet fed from the sheet feed system is abutted against the inkjet head unit becomes lower during both-side printing than during one-side printing.
