at power on despite the ink cartridge has been replaced with a new one.

the right column. If "No", proceed to the next step.
Troubleshooting
Table 3-9. Remedies for No I/C and Ink Out Errors
Step Check Point
1 Does the counter
value mis-match the
actual remaining ink
level?
2 Is the ink cartridge
sensor actuator
acting improperly?
Overview
Actions
The ink consumption counter, separately set for black
and color ink, adds up points according to ink weight
used to form one dot. This counter is reset (the value
returns to zero) when the I/C replacement sequence is
performed. If the counter is reset for any other
purposes, the following adversities will occur.
1. Enough ink is remaining in the cartridge, but the
printer shows the Ink low or Ink end condition and
can not continue to print.
2. Ink has run out but the printer continues to print and
starts false firing, which damages the printhead.
Explain the situation to the user well, and replace the
I/C with a new one.
Turn the both actuators (eight and left) manually and
check that they properly push the micro switches.
Then, also check that the actuators return to their
normal conditions shown in the figure below
automatically.
