Clean The Print Head Nozzles (Mac OS X)

The following contains instructions to check the nozzles for poor print quality and perform print head nozzle cleanings. If print results are faint or streaks are printed, the print head nozzles may be clogged. To improve print quality, perform print head cleanings or print head deep cleanings.

Caution: Only used the approved methods below to clean the print head. Use of other methods may further clog the nozzles on the print head and may cause permanent damage the print head.

Note: It is important to check the cleaning results by printing Nozzle Check Pattern after each cleaning. Cleaning and Deep Cleaning consumes a certain amount of ink. Only perform a cleanings when necessary.

   Any color that is not printed at all. (In the sample below, black ink is not printed at all.)
   
   
   - The pattern may vary depending on the printer.
   
   
   <Case C>
   
   There are missing lines partially in the pattern for the black ink.

   Until print head cleaning completes, do not try other operations. Print head cleaning will take about 60 seconds.
   
   
8. Print the Nozzle Check Pattern to examine the print head status.

12. Perform print head cleaning again. (Same as steps 8 to 11.)
    
    
13. If the pattern is still abnormal, perform print head deep cleaning.
    
    Note: Print head deep cleaning consumes a larger amount of ink than normal cleaning. Perform print head deep cleaning only when necessary.

3. Click 'OK'. Print head deep cleaning starts.
   
   Note: By clicking Initial Check Items before clicking Print Check Pattern, you can see the specific confirmation items in Nozzle Check.
   
   
   
   The Power lamp will blink and print head cleaning of the print head nozzles starts. The blink stops when print head cleaning is over.
   
   Until print head cleaning completes, do not try other operations. Print head cleaning will take about 2 to 3 minutes.
   
   
4. Print a Nozzle Check Pattern and examine it.
   
   
5. Perform Deep Cleaning again if necessary.
   
   
6. If the print quality does not improve, turn off the printer and let it sit for 24 hours or more, then perform Deep Cleaning again. The wait time may allow dried ink in clogged print head nozzles to liquefy, and resolve the problem.
   
   
7. If the print quality does not improve, replace the ink cartridge(s).
