Troubleshooting Shutdowns - User Message 
"Warning: Switch Power Off"
If a shutdown occurs, you will get the message “Warning: Switch 
Power Off” followed by:
n
Check Printhead Cleaner Path.
n
Check Paper Path.
n
Check Printhead Path (followed by (1), (2) or (3)).
A shutdown in each path will require different steps to resolve the 
problem as explained as follows.
WARNING
In each case, make sure that you power OFF the Printer before
attempting any procedures to resolve the problem.
Check Printhead Cleaner Path
This message appears whenever the Service Station Carriage does 
not move, either because of a bad cable connection, a defective 
motor or because of some obstacle inside the Service Station.
n
If the Printer is new, check that the Service Station cable (which is 
the grey flat cable with the grey connector) is plugged into the Main 
PCA. Make sure that the clips of the connector are closed 
completely. Check also that the Service Station cable is not damaged.
n
In already used Printers, power OFF the Printer and try to move 
the Service Station backwards and forwards to see whether it is 
blocked. Possible causes are: Printhead Cleaners incorrectly 
positioned, damaged or, even, pieces of paper within the Service 
Station. Remove the Printhead Cleaners or the pieces of paper 
and check whether the problem persists. 
n
If the problem disappears without the Printhead Cleaners, reinsert them 
into the Service Station and see whether the problem reappears. If the 
problem reappears, replace the complete set of Printhead Cleaners.
n
If the problem persists even without the Printhead Cleaners, then 
replace the Service Station (
Page 8-67) and recalibrate the Printer.
