Troubleshooting
Printing Does Not Start
nEnsure the printer is turned on.
If the POWER lamp is off, press the POWER button.
If the POWER lamp is ßashing green, the printer is initialising. Wait until the POWER 
lamp stops ßashing.
Note
äWhen printing a large amount of data such as a photo or graphics, it takes 
longer than usual to begin printing. While the POWER lamp is flashing, the 
computer processes the data and sends it to the printer. Simply wait until 
the processing is completed.
nEnsure the printer is securely connected to the computer.
Note
äIf you are using a switch box or other device, remove and reconnect the 
printer directly to the computer. Try printing again.
If printing is now successful, there may be a problem with the device.
Also there could be a problem with the cable(s). Replace the cable(s) and 
try printing again.

Troubleshooting
Printing Stops Before It is Completed
nCheck the status of the POWER lamp.
When the POWER lamp is ßashing 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 to not 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.
nHalt 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.
CautionäInside the printer, the area around the print head can become extremely 
hot. Do not touch the print head or nearby components.

Troubleshooting
Printer Moves But Does Not Print
nCheck the ink tanks. If empty, replace them.
nEnsure that the clear Þlm is completely removed from around the ink tank.
nEnsure that the ink tanks snap into place when you install them.
nIf 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.
áPrint Head Cleaning
áPrinting the Nozzle Check Pattern
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.
nCheck the protective tape has been removed from the print head.
Ensure that you align the print head after removing the tape and reinstalling the print 
head.
For details on print head alignment, refer to Straight Lines are Misaligned.

Troubleshooting
Print Head Holder Does Not Move to the Centre
nEnsure 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 ßashing green, the printer is initialising.
When the POWER lamp stops ßashing, open the front cover again.
nIf 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 centre.

Paper Does Not Feed Properly
nConÞrm the paper conditions.
¥ If non-Canon brand media, the paper is not too thick (less than 105 gsm / 28 lb).
¥ The number of sheets loaded does not exceed the recommended level.
¥ The paper is not creased, curled or wrinkled.
áCompatible Media Types
nEnsure that the left edge of the paper just touches the paper guide.
nWhen printing envelopes, refer to Envelopes in Printing Media, and prepare 
the envelopes before printing.
Once you have prepared the envelopes, load them in the printer in portrait orientation. If 
the envelopes are placed in landscape orientation, they may not feed properly.
nWhen using transparencies, load one sheet of plain paper in the printer Þrst, and 
then place the transparencies on top of it.
The last transparency may not feed properly unless there is a sheet of plain paper 
beneath it.
