1.3.6 Monitoring of the Amount of Remaining Ink
Outline
The amount of remaining cartridge ink is calculated in such a way that the amount of ink consumed for the
following operations is calculated by subtraction of remaining ink.
• Number of ink shots by printing and flushing
• Amount of ink suction by cleaning and filling
When the amount of remaining ink is updated, it is written into the ink IC chip.
A cartridge error is issued according to the amount of remaining ink.
Calculation of the amount of consumed ink
Ink discharging during printing and flushing
• The amount of ink consumed by ink discharging is calculated by counting the number of ink shots.
• CJV30 counts ink shots for each row of nozzles and performs calculation by taking account of dot sizes (small,
middle and large). Therefore, there will be a smaller error between the measured value and the calculated value,
as compared with the conventional models.
Ink suction during cleaning and filling
