Do not attempt to disassemble any components other than
those described below. Certain repairs can be done only at
the factory and can permanently damage the printer if not
done correctly.
The printer uses two printheads, Head B and Head C.
Although they are similar, they are not interchangeable.
One is for dark ink, the other for light ink. Make sure you
install the correct replacement head accordingly:
Head B (for dark ink; goes on the left)
F055040: “Printhead, IJ192-OAD”
Head C (for light ink; goes on the right)
F055050: “Printhead, IJ192- OAE”
When replacing the printheads, you have to perform
various adjustments. See Required Adjustments
on page 103.
