PROBLEM TO BE SOLVED: To automatically set a head drive voltage simultaneously with the replacement of an ink cartridge and save time and labor for a trouble for adjustment. SOLUTION: A head rank detection part sets a head rank by cutting a specified detection resistance or marking it with an electroconductive substance in accordance with a head rank and changing the combination of resistance values after setting detection resistances beforehand on a head cartridge 2. In addition, a printer reads the combined resistances as analog values through contact points 1, 2, and reads the head rank by converting the analog values into digital values, Thus it is possible to realize a high image quality print without the necessity to adjust the head cartridge 2 when replaced. |
