Check the status of the POWER lamp.
When the POWER lamp is flashing green, the printer is processing data. Printing a large amount of data such as a photo or graphics takes time for the computer to process the data, during which the printer may appear not to be functioning.
In addition, when continuously printing material that uses a large amount of black ink on plain paper, the printer will sometimes pause. In either case, simply wait until the processing is completed.
Halt the print job and turn the printer off for at least 15 minutes to cool the print head down.
The print head can overheat when continuously printing for long time. To protect the print head, the printer will sometimes pause automatically at a line break before resuming.
In this event, interrupt the print job at a convenient time and turn the printer off for at least 15 minutes.
Furthermore, when continuously printing graphics or photos with intense colors, printing may stop to protect the print head. In this case, printing will not resume. Turn the printer off and wait for at least 15 minutes.
Inside the printer, the area around the print head can become extremely hot. Do not touch the print head or nearby components.
Check the ink tanks. If empty, replace them.
Ensure that the ink tanks snap into place when you install them.
If there is plenty of ink but the printer does not print, clean the print head.
After cleaning the print head, print the nozzle check pattern to check that ink is being output normally.
If the problem is not resolved by cleaning the print head several times, the print head may be worn out. Contact a Canon service facility.
Ensure the printer is turned on.
The print head holder will not move unless the power is on. If the POWER lamp is off, close the front cover and turn the power on.
If the POWER lamp is flashing green, the printer is initializing.
When the POWER lamp stops flashing, open the front cover again.
If the front cover has been left open for a while, close and reopen it.
If the front cover is left open for more than 10 minutes, the print head holder moves to the right to prevent the print head from drying out. Close and reopen the front cover to return the holder to the center.
