6.5 Initial Print head Cleaning Procedure

A new print head contains a protecting liquid. Before using the print head, follow the procedure described below to
clean the print head.
(1) Pour cleaning solution into the solution tank.
Pour a generous amount of cleaning solution into the solution tank.
(2) Turn on the printer power supply.
When the power is turned on, the printer begins a self-test operation (the print head carriage and the feed
rollers move). When the self test has been completed, wait until the main menu is displayed on the LCD.
• Since ink has not yet been supplied to the printer, a "No Ink" alarm will sound after several minutes have
elapsed. This alarm does not indicate a malfunction, and no action is required.
(3) Move the print head carriage to the cleaning position.
(a) From the main menu, select [Cleaning Tool] and then press the ENTER key.
(b) From the submenu, select [Clean Post] and then press the ENTER key.
The print head carriage moves to the cleaning position and then stops.
(4) Check that the 3-way valve for the solution tank is set to the supply position.
• If the lever is at a different position, move it to the supply position.
