Step Check Point Action
1 Repeat the cleaning
7 or 8 times.
Unlike the previous products, the Stylus Color 900
is not equipped with the CL3 (dummy cleaning).
Therefore, you can repeat the cleaning every time
you press the Cleaning button without running a
self-test nor any printing.
2 Trying the initial ink
charge operation.
You can repeat the initial ink charge operation in
the way described below:
1. Using the exclusive program, reset the initial ink
charge flag in the EEPROM.
2. Turn the printer back on. (Refer to Chapter 5 for
details.)
3 Reinstalling the
printhead FFC.
Remove the upper case and check if the FFCs are
properly connected to the CN8 and CN9 on the
C265 Main board. Even though they are not
installed aslant as shown below, disconnect the
FFC once and connect them again, then run a print
check.
NOTE:
Before reinstalling the FFCs, be sure to
remove the frame (in red in the figure)
secured to the lower case with two
screws. Otherwise, proper continuity may
not be guaranteed despite the FFCs look
connected without slant.

Step Check Point Action
4 Check the cap for any
foreign matter, dirt, or
damage.
Remove the printer mechanism and release the
carriage lock at the back of the printer
mechanism to move the carriage unit away from
the home position. Then, have a close look at
the cap rubber and check for any problem below.
5 Has the valve cap fallen
off?
If a strong impact is applied to the valve cap in
the cap unit, it may fall off. Therefore, check that
the cap is securely attached to the cap unit.
Without this part, ink can not be absorbed.
