Title: Printing up to end part of print sheet without contaminating platen
Inventor: OTSUKI KOICHI
IPC: B41J11/00
Filed: 2000-09-27
Abstract: PROBLEM TO BE SOLVED: To provide a technology for printing up to the end part of a print sheet without hitting an ink drop against a platen by means of a dot printer recording dots on the surface of a print medium using a dot recording head provided with a plurality of dot forming elements ejecting ink drops. SOLUTION: A print sheet P is fed (sub-scan feeding) while being held by upstream side sheet feed rollers 25a and 25b. When the front end Pf of the print sheet P is located above the opening of a groove part 26m, printing is started by ejecting ink drops Ip from the nozzles #5-#9 of an print head 28. Since print is started when the front end Pf of the print sheet P is located in the rear of a nozzle #5 (upstream in the sub-scanning direction), an image can be printed up to the end of the print sheet P with no margin at the front end Pf regardless of some sheet feed error. Since a nozzle being used is located above the groove 26m, an ink drop not hitting the print sheet P does not adhere to the upper surface of a platen 26 to cause contamination of a print sheet being fed later. Subsequently, an image is printed onto the print sheet P by means of the nozzles #5-#9.
