Feeding apparatus, printing apparatus and feeding control method
摘要:
A feeding apparatus, a printing apparatus and a feeding control method can simplify control software significantly on a printing apparatus side and can provide freedom of design in the feeding apparatus. A communication port is provided for communication between the feeding apparatus and the printer. The feeding apparatus performs paper feeding operation after receiving a paper feeding command from the printer. When a sheet is fed in the printer, a feeding operation completion signal is transmitted to the printer. On the other hand, rotation of a feeding roller is resumed at a slightly earlier timing than a rotation start timing of a transporting roller. Therefore, back tension on the sheet by the feeding roller is minimized, and positioning the top of the sheet by the transporting roller is enhanced reliably.
