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
The table below shows the amount of ink consumed for various operations. (For the 4-color ink set)
