Using Ink
Canon has more engineers dedicated to creating quality ink for providing the best 
results for output on Bubble Jet printers than any other organization. Canon does 
not prohibit the use of third-party inks and the use of third-party inks does not 
invalidate the product’s limited warranty. However, Canon cannot guarantee the 
quality or performance of your unit when you are using inks from other suppliers.
Canon’s limited warranty does not cover damage caused to Canon’s Bubble Jet 
products that is attributable to the use of third party parts or supplies, including 
inks. The limited warranty remains in effect for its life once that particular damage 
has been properly repaired.
For optimum printing results, Canon recommends that you use the Canon 
BC-21e Color BJ Cartridge or the optional Canon BC-20 Black with your 
MultiPASS.
When replacing BJ tanks in the BC-21e Color BJ Cartridge, Canon 
recommends that you use the Canon BCI-21 Color and BCI-21 Black BJ 
Tanks.

Testing and Cleaning the BJ Cartridge Print Head
The print head in the BJ cartridge contains nozzles through which ink is propelled 
onto the paper. To maintain the best possible print quality, these nozzles need to be 
cleaned from time to time. Your MultiPASS is equipped with a print head cleaning 
function that does this.
Printing the Nozzle Check
Before cleaning the print head, you may want to print the nozzle check to test the 
BJ cartridge installed in the MultiPASS. This test shows if each print head nozzle is 
operating properly.
Follow this procedure to print the nozzle check:
1. Press 
Function.
2. Press 
Cleaning.
3. Press 
Set.
❑The MultiPASS prints the nozzle check.
When the BC-21e Color BJ Cartridge is installed, the pattern includes all four 
colors; yellow, magenta, cyan, and black. In the color pattern, you will notice that 
lines are missing between the colors. This is normal.
The following sample shows the nozzle check when the optional BC-20 Black
BJ Cartridge is installed:NOZZLE CHECK

Cleaning the BJ Cartridge Print Head
If your printouts become faint or streaked, or if their quality otherwise decreases, 
clean the print head. To maintain the best possible print quality, you need to clean 
the BJ cartridge print head from time to time.
1. Press 
Function.
2. Press 
Cleaning.
3. Use 
d or u to select HEAD CLEANING.
4. Press 
Set.
❑The MultiPASS cleans the print head.
When cleaning ends, the MultiPASS returns to standby mode.
You can perform the cleaning procedure up to five consecutive times if necessary.
If the problem persists, install a new BJ cartridge. Cleaning the print head consumes a small amount of ink. Cleaning too often 
reduces the amount of ink in the BJ cartridge.
If your printing is faint, you can often correct the problem by adjusting the print 
contrast and printing speed.

HEAD CLEANING
You can print the nozzle check to see if cleaning corrected the problem 
(see page 6-13).

When to Replace the BJ Cartridge
How frequently you need to replace your BJ cartridge or one of its BJ tanks 
depends on how you use your MultiPASS. If you print a good deal of graphics, 
halftones, or grayscales, you will need to replace the BJ cartridge more often than if 
you print mainly text. (See page A-5 for details on the life expectancy of BJ 
cartridges.)
To help ensure the maximum life for your cartridges, always follow the guidelines 
for cartridge maintenance given on page 6-11.
In general, you will need to replace the BJ cartridge in the following situations:
❑If you have been using the BC-21e Color BJ Cartridge for over six months, or 
a BC-20 Black BJ Cartridge for over a year.
❑If your printed output is not crisp and clear or has gaps in the characters 
(missing dots), even after you have cleaned the print head five times as 
described on page 6-14.
❑If your color printouts appear to be missing a color, even after you have 
cleaned the print head five times as described on page 6-14.
❑If the message CHANGE CARTRIDGE appears in the LCD display.
In general, you will need to replace an ink tank in the BC-21e Color BJ Cartridge in 
the following situations:
❑If your output is blank.
❑If your color printouts appear to be missing a color, even after you have 
cleaned the print head five times as described on page 6-14.
❑If the message BLACK INK EMPTY or COLOR INK EMPTY appears in the 
LCD display.
Use the procedure on the following page to replace an old BJ cartridge or change a 
BJ cartridge when switching between the BC-21e Color BJ Cartridge and any other 
optional BJ cartridge.
You only need to replace the BC-21e Color BJ Cartridge when the print head is 
damaged (or after printing approximately 2000 pages). If one of the BJ tanks 
(either color or black) in your BC-21e Color BJ Cartridge runs out of ink, refer to 
the procedure on page 6-22 to replace the BJ tank.
