3.7.4 NOZZLE BLOCKAGE CHECK 
One or more of the nozzles is blocked if you see these: 
•  Broken lines  
•  Uneven patches of white in the printouts.  
At this time, do this procedure: 
1.  Open the printer driver. (3.7.2) 
2.  In the Printer Properties window click “Maintenance”>”Nozzle Blockage Check”. 
3.  Do the instructions on the screen to print the test pattern. The sample below 
shows a normal and abnormal pattern.  
 
4.  Examine the pattern. Then check which color does not show. This information 
will let you know which nozzle is blocked.  
5.  Do the instructions on the screen to select the color you want to correct. Then 
clean the print heads. 
Important: 
•  Do “Clean Print Heads (Normal)” up to 3 times to correct the problem. Do 
   “Clean Print Heads (Full)” once if the problem continues. 
•  The “Full” cleaning uses a lot of ink. Do not do the “Full” cleaning until you 
   have done the “Normal” cleaning at least 3 times. 
•  For more, please refer to Section “4. Troubleshooting”.
