Abstract
To prevent a printing head not placed on a cleaning placing unit from being cleaned and prevent contamination of an ambient environment by cleaning liquid. An ink jet recording system includes a placement detecting unit configured to detect that a printing head 1 is placed on a cleaning placing unit 200. The placement detecting unit is configured to, when detecting that the printing head 1 is placed, transmit a signal based on placement confirmation for the printing head 1 to a controller connected to the printing head 1 placed on the cleaning placing unit 200.
Claims10
An ink jet recording system comprising:
- an ink jet recording apparatus including a printing head configured to house, on an inside, a nozzle that ejects ink, a charging electrode that charges particulate ink ejected from the nozzle, and a deflection electrode that deflects a flying direction of the ink charged by the charging electrode and eject, to an outside, the ink deflected by the deflection electrode and a controller including an ink supply unit connected to the printing head and configured to supply the ink to the printing head, a solvent supply unit connected to the printing head and configured to supply a solvent to the printing head, and a control unit configured to control ink supply from the ink supply unit to the printing head and control solvent supply from the solvent supply unit to the printing head, the ink jet recording apparatus performing printing on work using the ink supplied from the ink supply unit;
- a cleaning placing unit disposed in a place different from a setting place of the printing head at a time when the printing is performed by the ink jet recording apparatus, the printing head being placed on the cleaning placing unit when the printing head is cleaned using the solvent supplied from the solvent supply unit;
- and
- a placement detecting unit configured to be capable of detecting that the printing head is placed on the cleaning placing unit and, when detecting that the printing head is placed, send a signal based on placement confirmation for the printing head to the control unit connected to the printing head placed on the cleaning placing unit.
