Confirm that the ink tanks are installed in the appropriate positions.
See "Replacing an Ink Tank" on page 23.
The printer has a built-in ink absorber to hold the ink used during print
head cleaning, for example.
This error message indicates that the ink absorber is nearly full.
Press the OK button to cancel the error so you can continue printing.
Before the ink absorber becomes completely full, contact a Canon
service representative. (You will need to replace a particular part of the
printer.)
Canon recommends that you call for service as soon as this error
occurs. Once the ink absorber becomes completely full, printing cannot
be performed until the ink tank is replaced.
Disconnect the camera cable and reconnect it.
Depending on the model or brand of your PictBridge compliant device, you
may have to select a print mode before connecting the device.
You may also have to turn on the device or select Play mode manually
after connecting the device to the printer.
Perform necessary operations according to the instruction manual
supplied with your device.
If the error is still unresolved, there is a possibility that you are using a
digital camera or digital video camcorder that is not supported by this
printer. PictBridge-compatible digital camera or digital video camcorder
can be connected to your printer for Direct Printing.
Possible causes are as follows:
• Other than A4/Letter-sized plain paper is loaded. Press the OK
button to clear the error, and then load A4/Letter-sized plain paper in
the auto sheet feeder.
• Print head nozzles are clogged.
Press the OK button to clear the error, and then print the nozzle
check pattern to examine the print head condition.
For information how to print a nozzle check pattern, see "Printing the
Nozzle Check Pattern" on page 28.
• The paper output slot has been exposed to a strong light source
preventing current print head alignment.
Press the OK button to clear the error and move the printer to a
darker location.
After carrying out the above measures, if the problem continues after
aligning the print head again, press the OK button to clear the error, and
then perform manual print head alignment. For details on manual print
head alignment, see "Adjusting the Print Head Manually" on page 34.
