Title:
RECORDER, AND CONTROL METHOD FOR RECORDER
Document Type and Number:
Japanese Patent JP2009292093
Kind Code:
A
Abstract:

To provide a recorder and a control method for the recorder generating hardly a delay of scanning start-up timing of a recording means, even when adopting multistage driving of switching a conveying speed of a recording medium at two steps or more of multistage.

A conveying distance up to a target stop position (heading position) is found when a paper detecting sensor 39 detects a paper sheet under supply in a supply conveying process, and a speed profile is determined in response to the residual conveying distance. Two-stage driving for accelerating the first fixed speed area to the second fixed speed area is adopted therein when the acceleration from the first fixed speed area to the second fixed speed area is allowed in the residual conveying distance. A CR time (estimated time) provided by subtracting a stop stable time from a CR moving time from start-up of a CR motor up to a printing start time position is reduced therein into a period (PF period Tpf), and a period in every one step of a PF motor 25 is subtracted to satisfy Tpf0 sequentially from a target stop position side along the speed profile, based on the PF period, so as to find a start-up allowance position.
