3.4 Verification
(1) Print the nozzle check pattern when replacing the print head, sheet feeder unit, purge unit, or carriage unit. (2) Check the connection with PC and print the nozzle check pattern when replacing the PCB.

4. Printer Transportation Method
This section describes the procedures for transporting the printer (for example, when returning after repair). (1) Keep the print head in the carriage. (2) Turn off the power and ensure that it is properly capped at home position.

If the print head is left alone by itself, the ink may solidify. Therefore, keep the print head (with ink tank) in the carriage even when transporting. Also, secure the carriage at home position to prevent it from moving and applying stress to the encoder film during transportation.

If the print head must be transported by itself, perform the following: 1. Install ink tanks for each color. (to prevent nozzles from drying) 2. Install the orange protective cap on the print head. (to prevent damage to the print head due to shock etc.)
