Canon BJ-10sx 사용자 설명서

If you are having print quality problems, you need to clean the 
print head. Paper dust or ink may get clogged in an ink nozzle in 
the ink cartridge. Performing the print head cleaning procedure 
should clear up this problem. 

The printer automatically cleans the print head when you follow 
these steps: 

1. Turn on the printer. The 

POWER

 and 

ERROR 

indicators 

come on.

2. Open the top cover and insert a sheet of paper into the 

printer.

3. Press the 

 button to advance the paper.

4. Press the 

button. The 

ON LINE 

indicator lights.

5. Press the 

and 

buttons at the same 

time. The printer beeps.

6. Immediately press the 

button. (The printer beeps.) 

The printer cleans the print head and prints a check 
pattern. 

If the printer beeps before you press the 

button, it will 

clean the print head but not print the check pattern. 

Inspect the check pattern. There should be a horizontal line 
between each pair of vertical lines. If any horizontal is missing, 
repeat the cleaning process until all lines are present.

If the quality of your printed output is still not crisp and clear 
after cleaning the print head, try the cleaning procedure again. If 
your output is not satisfactory after cleaning the print head 
several times, replace the ink cartridge.

NOTE: Cleaning the print head consumes a small amount of ink. 
Repeating this procedure unnecessarily reduces the life of the ink 
cartridge.
