2-4. Troubleshooting by Symptom
*1: Before replacement of the logic board ass'y, check the waste ink amount (by service test print or EEPROM information print). If the waste ink amount is 7%

the logic board ass'y.
[See Section 3-3. Adjustment / Settings, (6) Service mode, for details.]
*2: Replace the print head only after the print head deep cleaning is performed 2 times, and when the problem persists.
