Title: Ink jet printer
Inventor: SUZUKI MASASHI
IPC: B41J2/01
Filed: 1997-02-18
Abstract: PROBLEM TO BE SOLVED: To prevent formation of an image on a recording medium wherein deformation or the like is caused by heat, in an ink jet printer wherein solid ink is melted by heating and jetted. SOLUTION: The kind of paper being set is stored in memory in a paper setting process at S1, a timer is started at S3 and standby is made, while solid ink is melted by heating, at S5 to S9. When recording data are inputted (S7: YES), the time passing during the standby is measured from a value of the timer at S11 and, moreover, the kind of the paper and environmental data (temperature and humidity) are inputted at S13 and S15. The range wherein deformation or the like is caused in the paper by exposure to the heat of a head varies according to the time passing, the kind of the paper, the temperature and the humidity. Based on them, accordingly, a paper feed amount corresponding to the range wherein the deformation or the like is expected to occur is calculated (S17), and after the paper is carried preliminarily by the paper feed amount (S19), a recording process is executed (S21).
