What to Do

A cartridge may not be installed properly or this printer does not support the cartridges.

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

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

1. Open the scanning unit / cover.
    

2. Open the right and left ink tank covers.

   
   
    

    Important

   • When removing cartridges, always open the ink tank covers. If the cartridges are removed without opening the ink tank covers, an Ink Flush will be required that will consume a large amount of ink.
      

3. Grab knob (A) on the cartridge locking cover to open it.

   
   
    

4. Remove the C (color) and B (black) cartridges.

   
    Important

   • When removing the cartridges, 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 or print head nozzles on a cartridge. The printer may not print properly if you touch them.

     
     
      

5. Reinstall the cartridges properly.

   Install the C (color) cartridge in the left holder and the B (black) cartridge in the right holder.

   
   
    

    Important

   • Insert the cartridge gently so that it does not hit the electrical contacts in the back of the cartridge holder.

     
     
      

6. Close the cartridge locking cover and push it down.

   
   
    

7. Press down both joint buttons.

   
   
    

8. Close both ink tank covers.
    

9. Gently close the scanning unit / cover.

   
   
    

If this does not solve the problem, service is required.

 Important

• If you unplug the power cord, all the faxes stored in the printer's memory are deleted.
   
• Do not tilt the printer when moving it since the ink may leak out.
   
• When transporting the printer for repairing it, see Repairing Your Printer.
