Abstract

PROBLEM TO BE SOLVED: To prevent paper retaining suction force from lowering, thereby implementing good paper transportation by a cleaning mechanism comprising pins 5 fitting in pitch of air vents and heater-furnished roller on a drum formed with air vents. SOLUTION: Air suction means for suction from air vents are set on the drum 1, and a print head 3 is also set at the position opposite to the drum 1. Paper 6 is retained on the drum 1 by means of guide rollers 5 and suction means 4. When the drum 1 rotates in the direction of arrow, pins 8 fitting in the pitch of air vents 9 and a cleaning roller 5 furnished with a heater 7 follow and rotate in the direction of arrow while being in engagement with the air vents. By the agency of rotation and heat of the heater 7 installed within the cleaning roller 5, debris 10 such as solid ink solidified in the air vents 9 of the drum 1 is melted to then be excluded outward of the drum 1.

に空気孔を塞いでしまい、目詰まりを引き起こす。When printing is performed without paper on the paper transport means due to paper jam or the like, air holes in the paper transport means are clogged with ink. In particular, when a hot-melt type ink (solid ink) is used, the ink that has entered the air holes solidifies and completely blocks the air holes, causing clogging.

があった。When the air holes of the sheet conveying means are clogged, the suction force is reduced, so that the sheet cannot be sucked and the sheet is partially lifted. Since the print surface of the paper comes into contact with the print head due to the lifting, there is a problem that the heat of the print head melts the ink image on the print surface to lower the print quality and cause paper jam.
