Issue

Cause and solution

When FINE Cartridges run out of ink, replace them using the following steps.

Caution

Handling FINE Cartridges

Do not touch the electrical contacts or Print Head Nozzles on a FINE Cartridge. The machine may not print out properly if you touch it.

(A) Electrical Contacts

(B) Print Head Nozzles

To maintain optimal printing quality, we recommend the use of specified Canon brand FINE Cartridges. Refilling ink is not recommended.

Once you remove a FINE Cartridge, replace it immediately. Do not leave the machine with FINE Cartridges removed.

Replace empty cartridges with new ones. If you insert FINE Cartridges that has been removed once, the machine may not print out properly due to some reasons such as clogging of the nozzles. Furthermore, with such cartridges, the Low Ink Warning may not be displayed properly.

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

Caution

If a FINE Cartridge runs out of ink, you can print with either Color or Black FINE Cartridge, in whichever ink remains, only for a while. However the print quality may be reduced compared to when printing with both cartridges. Canon recommends to use new FINE cartridges in order to obtain optimum qualities. Even when printing with one ink only, print with leaving the empty FINE Cartridge installed. If either of the Color FINE Cartridge or Black FINE Cartridge is not installed, an error occurs and the machine cannot print. For information on how to configure this setting, refer to the PC Printing Guide on-screen manual.

Color ink may be consumed even when printing a black-and-white document or when black-and white printing is specified. Color ink is also consumed in Print Head Cleaning and Print Head Deep Cleaning, which may be necessary to maintain the machine's performance.

When you start printing after replacing the FINE Cartridge, Print Head Cleaning is performed automatically. Do not perform any other operations until Print Head Cleaning finishes.

If the straight line is misaligned or the Print Head position is misaligned, align the Print Head position. See "Aligning Print Head on the Machine".

Replacing FINE Cartridges

Cause and solution

Print Head nozzles are clogged

See "Printing the Nozzle Check Pattern" and perform any necessary maintenance operation.

Clean the Print Head if lines are missing or if white streaks appear in the printed nozzle check pattern. Cleaning unclogs the nozzles and restores the print head condition. Note that cleaning the Print Head causes used ink to be absorbed in the ink absorber. Cleaning the Print Head consumes ink, so perform Print Head Cleaning only when necessary.

1. Make sure that the machine is turned on.

2. Start Print Head Cleaning.

(1) Press the Maintenance button repeatedly until H appears.

(2) Press the Black or Color button.

Print Head Cleaning starts.

Do not perform any other operations until Print Head Cleaning finishes. This takes about one minute.

3. Confirm the condition of the Print Head.

When Print Head Cleaning finishes, the LED returns to the standby mode.

Print the nozzle check pattern to check the print head condition.

See "Printing the Nozzle Check Pattern".

Caution

If the problem is not resolved after performing Print Head Cleaning twice, try Print Head Deep Cleaning. See "Print Head Deep Cleaning".

Print Head Cleaning

If print quality does not improve by standard Print Head Cleaning, try Print Head Deep Cleaning, which is a more powerful process. Note that cleaning the Print Head causes used ink to be absorbed in the ink absorber. Print Head Deep Cleaning consumes more ink than standard Print Head Cleaning, so perform this procedure only when necessary.

1. Make sure that the machine is turned on.

2. Start Print Head Deep Cleaning.

(1) Press the Maintenance button repeatedly until y appears.

(2) Press the Black or Color button.

Print Head Deep Cleaning starts.

Do not perform any other operations until Print Head Deep Cleaning finishes. This takes about two minutes.

3. Confirm the condition of the Print Head.

(1) Print the nozzle check pattern to check the print head condition.

See "Printing the Nozzle Check Pattern".

(2) If the problem is not resolved, perform Print Head Deep Cleaning again.

(3) If this does not solve the problem, a FINE Cartridge may have run out of ink. Replace it with a new one. See "Replacing FINE Cartridges".
