Ink Cartridge
The error code should indicate which cartridge is
suspected. Check the ink cartridge detection resistor
pad (top left of each cartridge). The resistance
should be 15K to 25K Ohms. If the resistance is
incorrect, replace the ink cartridge.

Logic Board
Disconnect the CNID connector from the left con-
nector card. With the ink cartridge installed, check
the resistance between the pins designated for each
cartridge sensor (pins 1 and 2; 3 and 4; 5 and 6; 7
and 8). Pin 9 is not used. The resistance should be
15K to 25K Ohms. If the resistance is
correct,
replace the logic board, left connector card, and left
connector cable.
If you replace the logic board, go to the
position adjustment, and the direction offset adjust-
ment.
