What to Do

A print head may not be installed properly or may not be compatible with this printer.

If you are printing, press the printer's Stop button to cancel printing.

Remove the print heads and reinstall them properly following the steps below. This may resolve the error.

1. Open top cover.

   

2. Close ink valve.

   Tilt the ink valve lever tightly to the left.

   

3. Grab knob (A) on print head locking cover to open it.

   

4. Pull the print head (B) and shift it slightly toward you.

   

5. Remove left and right print heads.

   

   Important

   • When removing the print heads, handle them carefully so that ink does not spatter.
   • Do not touch the tube or other parts inside the printer. Touching these parts may cause the printer to malfunction.

   • Do not touch the gold terminal (C) or print head nozzles (D) on a print head. The printer may not print properly if you touch them.

     

6. Reinstall print heads properly.

   Install the print head labeled "L" in the left holder and the print head labeled "R" in the right holder.

   

7. Close print head locking cover (E) and push it down.

   Press firmly the print head locking cover until it clicks into place.
