Check & Actions
Make sure the I/C was replaced with the new one in
the I/C replacement sequence. If not, explain the
situation to the user well and replaced the I/C with
new one in the I/C replacement sequence.
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 and I/C is replaced. If the
I/C is replaced with the used I/C in the I/C
replacement sequence, the following adversities will
occur.
• Ink has run out but the printer continues to print
and starts false firing, which damages the print
head.
If the new I/C is installed without entering the I/C
replacement sequence, the ink consumption counter
is not reset and the following adversities will occur.
• Enough ink is remaining in the cartridge, but the
printer shows the Ink low or Ink end condition and
can not continue to print.
