Printhead Errors 
 
(First Digit = 0, 1, 2, 3, 4, 5)
NOTE
If you think your Printer is requesting you to replace your
Printheads too frequently you can check Printhead nozzle status
by printing the Diagnostic Print 
⇒ 
NOTE
Do not touch, wipe or attempt to clean the Printhead nozzles.
This can damage the Printhead and reduce print quality (See
Page 9-6 for Maintenance Procedures).
NOTE
When replacing Printheads:
n
Ensure that you have the correct Printhead.
n
Ensure that the Printhead is the correct color for that slot.
n
Ensure that the protective cap is removed from the 
Printhead.
n
Check the empty slots to see if they need cleaning. In extreme 
circumstances, when a Printhead is inserted, it is possible that 
the Printer will not recognize it due to the build-up of ink on 
the electrical connection between the Printhead and the 
Printhead carriage.
NOTE
If all 6 Printheads present the same error message, check the
following:
n
All Printheads installed are NOT  wrong type i.e. wrong 
model, Setup Printheads instead of normal etc.
n
If you replace or reseat  Printheads one at a time  and the  
error persists for all Printheads, this  indicates a hardware 
failure. Do the following:
1 Check that the Carriage Tube Connector is correctly connected 
to the Carriage.
2 Check that the Trailing Cable connections between the 
Carriage Assembly and the Main PCA and if the cable is 
damaged, replace it 
3 Replace the Carriage Assembly 
⇒ 
4 Replace the Main PCA
