Description

If printing is faint, cleaning the Printhead may improve results. Print a nozzle check to determine if any of the nozzles are clogged.

Solution

Choose one of two Printhead cleaning modes ( Head Cleaning A or Head Cleaning B ), depending on the problem to resolve.
  • Head Cleaning A
Use this mode if printing is faint or contains foreign substances. This method of cleaning consumes the least amount of ink.
It takes about three minutes to complete.
  • Head Cleaning B
Use this mode if no ink is ejected at all, or if Head Cleaning A does not solve the problem.
It takes about three and a half minutes to complete.
CAUTION
  • Do not remove the Maintenance Cartridge or ink tanks during either Head Cleaning A or Head Cleaning B.
NOTE
  • If printing does not improve after Head Cleaning B, try repeating Head Cleaning B once or twice. If this still does not improve printing, the Printhead may have reached the end of its useful life. Contact your Canon dealer for assistance.
  • Nozzles are periodically checked to ensure they are clear. Configure the settings on the Control Panel menu in Nozzle Check.

 

Perform cleaning as follows.

1. On the Tab Selection screen of the Control Panel, press  or  to select the Settings/Adj. tab ().

NOTE
  • If the Tab Selection screen is not displayed, press the Menu button.

 

 

2. Press the OK button.
The Set./Adj. Menu is displayed.
 
3. Press  or  to select Maintenance, and then press the OK button.
 
4. Press  or  to select Head Cleaning, and then press the OK button.
 
5. Press  or  to select Head Cleaning A or Head Cleaning B, and then press the OK button.
Head cleaning is now executed.
 
6. Print a test pattern to check the nozzles, and determine whether cleaning has cleared the nozzles.
 
Printing a Nozzle Test:
 
If printing is faint or affected by banding in different colors, make sure the Printhead nozzles are clear by printing a test pattern to check the nozzles.
NOTE
  • Nozzles are periodically checked to ensure they are clear. Configure the settings on the Control Panel menu in Nozzle Check.

 

1. Load unused paper.

 
2. On the Tab Selection screen of the Control Panel, press  or  to select the Settings/Adj. tab ().

NOTE
  • If the Tab Selection screen is not displayed, press the Menu button.

 

3. Press the OK button.

The Set./Adj. Menu is displayed.
 
4. Press  or  to select Test Print, and then press the OK button.
 
5. Press  or  to select Nozzle Check, and then press the OK button.
The printer now prints a test pattern for checking the nozzles.
 
6. Check the printing results.
If the horizontal lines are not faint or incomplete, the nozzles are clear.

If some sections of the horizontal lines are faint or incomplete, the nozzles for those colors are clogged.

If horizontal lines are faint or incomplete, follow the steps below and check again for nozzle clogging.
 
1. Clean the Printhead.
 
2. Print a test pattern to check the nozzles.
NOTE
  • If you repeat these steps several times but the horizontal lines are still faint or incomplete you may need to replace your printhead.
