Canon Printer Nozzle Check Only One Blue Bar
Description
The following contains instructions to check the nozzles for poor print quality and perform cleanings of the print head nozzles as necessary.
Solution
When Printing Becomes Faint or Colors Are Incorrect
If print results are blurred or colors are not printed correctly, the print head nozzles are probably clogged. Follow the procedure below to print the nozzle check pattern, check the print head nozzle condition, then clean the Print Head.
If printed ruled lines are misaligned or print results are otherwise unsatisfactory, aligning the Print Head may improve print quality.
Important
Do not rinse or wipe the Print Head and ink tanks. This can cause trouble with the Print Head and ink tanks.
Note
Before performing maintenance
Make sure that the orange protective tape does not remain on the ink tank.
Open the Scanning Unit (Cover) and make sure that all lamps on the ink tanks are lit red.
Increasing the print quality in the printer driver settings may improve the print result.
When the Print Results Are Blurred or Uneven:
Step 1
See Printing the Nozzle Check Pattern .
See Examining the Nozzle Check Pattern .
After cleaning the Print Head, print and examine the nozzle check pattern.
If there are missing lines or horizontal white streaks in the pattern:
Step 2
See Cleaning the Print Head .
If the problem is not resolved after cleaning the Print Head twice:
Step 3
See Cleaning the Print Head Deeply .
Note
When you have performed the procedure until step 3 and the problem has not been resolved, turn off the power and clean the Print Head deeply again after 24 hours. Do not disconnect the power plug when turning off the power.
If the problem is still not resolved, the Print Head may be damaged. Service is required
