INKJET PRINTING DEVICE AND METHOD FOR CONTROLLING SAME

Title:

INKJET PRINTING DEVICE AND METHOD FOR CONTROLLING SAME

Document Type and Number:

WIPO Patent Application WO/2021/193009

Kind Code:

A1

Abstract:

Provided is an inkjet printing device in which when a disconnection detection circuit 37 detects malfunction, a control unit 43 of a temperature control unit 27 manipulates a duty ratio so that said duty ratio is distributed to normal heat rollers 31. Drying defects do not occur because it is possible to use other heat rollers 31 to compensate for the amount by which heat decreases as a result of malfunction of a heat roller 31. There is no need to immediately stop printing processing at the point in time at which malfunction is detected by the disconnection detection circuits 37, and maintenance work can be performed after taking sufficient time to prepare therefor. It is possible to minimize the downtime of the printing device because maintenance work can be performed quickly.
