Chapter 3 Maintenance and Disassembly
Procedure
1. Load paper into the sheet feeder.
2. Open the printer control dialog box.
3. Click on the Cartridges tab.
4. Click on Clean Print Nozzles.
5. The printer feeds a sheet of paper and prints the nozzle test pattern.
6. Examine the test pattern.
This example shows a test pattern of all nozzles functioning correctly on the black print cartridge.
This is a comparable example for the color cartridge. The actual pattern will be printed in color.
7. Compare the diagonal lines at the top and bottom of the test pattern.
Look for a break in the diagonal line. A break in the line shows clogged nozzles.
If the bottom line shows improvement, run the test again.
If the improvement continues, run the test a third time.
If all the nozzles are not printing after running the test three times, continue with step eight.
8. If the print quality still has not improved, remove and reinstall the print cartridge.
9. Repeat the Nozzle Test.
