Description

Replace any ink tanks that are empty.

Solution

When the ink tanks run out of ink, follow the procedure below to replace them.

IMPORTANT
  • To maintain optimal print quality, we recommend the use of specified Canon brand ink tanks. Refilling the ink is not recommended.

  • If you remove an ink tank, replace it immediately. Do not leave the machine with ink tanks removed.

  • Use new ink tanks for replacement. Installing used ink tanks may cause the nozzles to clog. Furthermore, with such ink tanks, the machine will not be able to inform you when to replace the ink tanks properly.

  • Once an ink tank has been installed, do not remove it from the machine and leave it out in the open. This will cause the ink tank to dry out, and the machine may not operate properly when it is reinstalled. To maintain optimal printing quality, use an ink tank within six months of first use.

NOTE

Color ink may be consumed even when printing a black-and-white document or when black-and-white printing is specified.

Every ink is also consumed in the standard cleaning and deep cleaning of the Print Head, which may be necessary to maintain the machine's performance. When an ink tank is out of ink, replace it immediately with a new one.

 

  1. Make sure that the power is turned on, and open the Paper Output Tray gently.

  2. Lift the Scanning Unit (Cover) until it stops.
    The Print Head Holder moves to the replacement position.

CAUTION
Do not hold the Print Head Holder to stop or move it forcibly. Do not touch the Print Head Holder until it stops completely.
IMPORTANT
  • Do not place any object on the Document Cover. It will fall into the Rear Tray when the Document Cover is opened and cause the machine to malfunction.

  • If the Document Cover is open, you cannot open the Scanning Unit (Cover). Be sure to lift the Scanning Unit (Cover) with the Document Cover closed.

  • Do not hold the LCD or the Operation Panel.

  • Do not touch the metallic parts or other parts inside the machine.

  • If the Scanning Unit (Cover) is left open for more than 10 minutes, the Print Head Holder moves to the right. In this case, close and reopen the Scanning Unit (Cover).

NOTE
The machine may make operating noise when the Print Head Holder moves to the replacement position.
 
  1. Remove the ink tank with the lamp flashing fast.

    Push the tab (A) and lift the ink tank to remove.

    Do not touch the Print Head Lock Lever (B).

IMPORTANT
  • Handle the ink tank carefully to avoid staining of clothing or the surrounding area.

  • Discard the empty ink tank according to the local laws and regulations regarding disposal of consumables.

  1. Prepare the new ink tank.

    1. Take a new ink tank out of its package, pull the orange tape ( ) in the direction of the arrow to peel it off, then remove the film ( ).

Make sure that the film is completely removed from the air hole (C).

If the air hole is blocked with the remaining film, ink may leak out or may not eject properly.

  1. Hold the orange protective cap (D) as indicated in the figure below, then twist and remove it from the bottom of the ink tank.
    Remove the protective cap while holding it to prevent the ink from staining your fingers.
    Discard the protective cap once it is removed.

IMPORTANT

Do not touch the electrical contacts (E) on the ink tank. It can cause the machine to malfunction or become unable to print.

IMPORTANT

  • If you shake the ink tank, the ink may spill out and stain your hands and the surrounding area. Be careful to handle the ink tank.

  • Do not squeeze the side of ink tanks as this may cause the ink to leak out.

  • Be careful not to stain your hands and the surrounding area with ink on the removed protective cap.

  • Do not reattach the protective cap once you have removed it. Discard it according to the local laws and regulations regarding disposal of consumables.

  • Do not touch the open ink port once the protective cap is removed, as this may prevent the ink from being ejected properly.

  1. Install the new ink tank.
