2.4.2 Counters

The EEPROM on the control board stores the values for the following counters to manage the ink system:


Protect Counter A
This counter counts total amount of drained ink. If the counter value exceeds 75,000, the maintenance
error occurs and the current printing job stops as a result. (Refer to Section 1.5.8.) The occurrence of
this error requires
1.5.1 and Chapter 3.) The current value for this counter can be found in the default setting mode.
(Refer to Section 1.5.2.) To reset the counter, perform
operation or the reset operation using the adjusting program.


Black/Color One-time Flag
This flag set in the
charging is normally performed only when the user begins to use a new printer. It is, however,
performed on the condition that the user needs to reinstall the ink cartridge which has been removed
before transporting the printer some distance to avoid ink leakage. The procedure for the initial ink
charge for this occasion is as follows:
1. Turn the printer on and remove the ink cartridges.
2. Turn the printer off, and the printer starts ejecting ink from the printheads and tubes to the
waste ink drain pads.
3. After transportation, install the ink cartridges.
4. Turn the printer on, and the printer enters the initial ink charge mode.


Ink Consumption Counter
This counter accumulates the amount of ink used throughout the printing, cleaning, and flushing
operations after a new cartridge is installed. The value is used to monitor the ink amount remaining in
the ink cartridge. The counter value is reset when the ink cartridge is removed. This counter is
normally reset with an ink low condition detected by the ink end sensor *. Then the Ink End error
occurs when the counter exceeds the specified value.
Note) The ink end sensor detects an ink end condition when the remainder of the ink drops to 5 % of
the capacity.
Be sure to replace the waste ink drain pads when the
