2.4.2 Counters

This printer is equipped with following counters. The values for the counters are stored in the EEPROM on
the main control board.
Y
Protect Counter A
This counter is used to manage the total amount of drained ink. If the counter value exceeds 65,000, a
maintenance error occurs and the current printing job stops consequently. (Refer to Section 1.4.11.) This
error requires EEPROM clearing and waste ink drain pad replacement. (Refer to Section 1.4.3 and
Section 3.2.9.) The current value for this counter can be found in the default setting mode. (Refer to
Section 1.4.5.) To reset the counter, clear EEPROM through the control panel or by running the
adjustment program.
Y
Protect Counter C
This counter is used to manage the amount of ink flushed in the left waste ink drain pad located at left
end of the paper eject drive unit. The counter value corresponds to the amount of ink accumulated in the
pad. If the counter value exceeds the specified value, a maintenance error is indicated and the current
printing job stops consequently. (Refer to Section 1.4.11.) With an occurrence of this error, the waste ink
drain pads must be replaced. (Refer to Section 1.4.3 and Section 3.2.9.) The current value for this
counter can be found in the default setting mode. (Refer to Section 1.4.5.)
Y
Black/Color One-time Flag
This flag set in the EEPROM sets a limit to prevent the user from running frequent initial ink charging.
Normally, initial ink charging is performed when the user starts using a new printer. The flag is reset by
clearing the EEPROM through the control panel or adjustment program.
Y
Ink Consumption Counter
This counter monitors the amount of ink used throughout the printing, cleaning, and flushing operations
after a new cartridge is installed. The value determines the amount of ink remaining in the cartridge. This
counter is reset when the cartridge is removed.
Be sure to replace the waste ink drain pads and the left ink pad when the EEPROM is cleared. (Refer to
Chapter 3.)
