4.1.3 Head Data Writing Operation

Data unique to the specific black printhead used in the printer is stored in the EEPROM on the C172 MAIN
board. This value must be rewritten to the EEPROM when the printer mechanism, main board, or EEPROM
chip is replaced, and also whenever the EEPROM is reset. On the other hand, when an optional color head is
installed on the carriage, color head data is automatically set in the printer.
Before running this program, be sure the interface setting is set to parallel•or auto select.
1. Connect a PC to the target printer using a parallel interface cable, and turn the printer on.
2. Load BASIC on the PC and run the program ST1500.BAS. Then the main menu appears, as shown
below:

"Customer Data." (For example, EAI: 20000A00 ). Then the main menu appears, as shown below.
