“The ink may have run out. You are 
recommended to stop printing, then 
replace the ink tank.” (when printing is 
in progress) / “The ink may have run 
out. Replacing the ink tank is 
recommended.” (when printing is not in 
progress)
U044 Ink may have run out (The lamp on the ink tank flashes). 
If printing is in progress, you are recommended to press the machine’s 
Stop/
Reset  button to stop printing, replace the ink tank, and then print again.
If printing is in progress and you want to continue printing, press the machine’s 
OK  button. Then printing can continue. Replacing the ink tank is recommended 
after the printing. The machine may be damaged if printing is continued under 
the ink out condition.
See “Replacing an Ink Tank” on page 103.
Notez If multiple ink lamps are flashing red, see “Getting the Color or Black Ink 
Status Information” on page 103 and check the status of each ink tank.
z Since printing in this condition may cause the contents of the fax to be lost, 
the machine stores received faxes in memory without printing until the ink 
tank is replaced. Print the fax stored in memory manually after replacing the 
ink tank. You can set the machine to print received faxes forcibly without 
storing them in memory, but a part of contents or all contents of the fax may 
not be printed.
“The clear ink tank is empty. Replacing 
the ink tank is recommended.”
U045 The clear ink tank is empty.
You are recommended to replace the clear ink tank with a new one.
If printing is in progress and you want to continue printing, press the machine’s 
OK
 button. Then printing can continue. Replacing the clear ink tank is 
recommended after the printing. 
If the clear ink runs out, you will not be able to print on plain paper.
See “Replacing an Ink Tank” on page 103.

Replace the clear ink tank with a new one.
If you do not replace the clear ink tank, press the machine’s 
Stop/Reset button

Print quality will deteriorate considerably and the feeder behind the cassette 
may be damaged if printing on plain paper is continued under the clear ink out 
condition. For this reason, you cannot print on plain paper until the clear ink tank 
is replaced with a new one.
See “Replacing an Ink Tank” on page 103.
NoteUntil the clear ink tank is replaced, the machine will not be able to print the 
received fax and will store it in its memory. The fax stored in memory needs to 
be printed manually.
ImportantIf you accidentally unplug the power cord and the power is turned off when the 
clear ink has run out, the error may not be cleared even after pressing the  Stop/
Reset  button. Replace the ink tank with a new one.

If printing is in progress, press the machine’s 
Stop/Reset button to stop printing, 
replace the ink tank, and then print again. Printing under the current condition 
may damage the machine.
To continue printing, you need to release the function for detecting the

caused by continuation of printing under the ink out condition.
See “Replacing an Ink Tank” on page 103.
Notez If the function for detecting the remaining ink level is disabled, the ink tank in 
gray is displayed on the LCD when checking the current ink level.

“The ink absorber is almost full. Press

service center.” The machine 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.
However, because printing is disabled once the ink absorber becomes 
completely full and until the ink absorber is replaced, you are recommended to 
contact your Canon service representative as early as possible. (You will need 
to replace a particular part of the machine.)
“Auto head align has failed. Press OK 
and repeat operation. ” Possible causes are as follows:
z
Print Head nozzles are clogged. 
Press the  OK button to dismiss the error message, and print the nozzle 
check pattern to check the status of the Print Head. See “Printing the Nozzle 
Check Pattern” on page 114 and “Printing Does Not Start/Printing Is Blurred/
Colors Are Wrong/Straight Lines Are Misaligned” on page 143.
z Plain paper of size other than A4 or Letter is loaded in the Cassette.
Press the  OK button on the machine to dismiss the error message, then load 
four sheets of A4/Letter-sized plain paper in the Cassette.
Automatic Print Head Alignment can only be performed using paper from the 
Cassette. For Automatic Print Head Alignment, always load paper in the 
Cassette.
z The Paper Output Slot is exposed to strong light.
Press the  OK button to dismiss the error message, and then adjust your 
operating environment and/or the position of the machine so that the Paper 
Output Slot is not exposed directly to strong light.
After carrying out the above measures, if the problem continues after aligning 
the Print Head again, press the  OK button to dismiss the error message, and 
then perform Manual Print Head Alignment. For details on Manual Print Head 
Alignment, see “Manual Print Head Alignment” on page 119.
