Cleaning Your Machine
This section describes the cleaning procedure that is needed to maintain your machine.
„Cleaning the Exterior of the Machine
Be sure to use a soft cloth such as eyeglasses cleaning cloth and wipe off dirt on the surface 
with it gently. Smooth out wrinkles on the cloth if necessary before cleaning.
„Cleaning the Platen Glass and Document Cover
With a clean, soft, lint-free cloth, wipe the Platen Glass (B), the inner side of the Document 
Cover (white sheet) (A), and the FAU lamp (C) gently. Make sure not to leave any residue, 
especially on the Platen Glass.
Caution
zDo not use tissue paper, paper towels, or similar materials for cleaning. Paper tissue powders or fine 
threads may remain inside the machine and cause problems such as a blocked Print Head and poor 
printing results. Use a soft cloth to avoid scratching the components.
zNever use volatile liquids such as thinners, benzene, acetone, or any other chemical cleaner to clean 
the machine, as this may cause a malfunction or damage the machine’s surface.
Caution
Be sure to turn off the power and disconnect the power cord before cleaning the machine.
Important
zWhen cleaning the exterior of the machine, do not use tissue paper, rough-textured cloth, or 
similar materials, as this may scratch the surface.
zNever use neutral detergent or volatile liquids such as thinners, benzene, acetone, or any other 
chemical cleaner, as this may damage the surface.
Caution
Be sure to turn off the power and disconnect the power cord before cleaning the machine.

							74Troubleshooting
An Error Message Is Displayed on the LCD
If an error message is displayed on the LCD, take the corresponding action described below.
MessageAction
“There are no photos in memory card.”
zThere are no image data saved on the memory card that can be read by this 
machine.
zThe machine may not recognize the file if the file name or the folder path 
contains certain characters. Use only alphanumeric characters.
zPhoto data edited or processed on a computer must be printed from the 
computer.
“The following ink may have run out. 
Replacing the ink tank is 
recommended.”
U041If the lamp on the ink tank is flashing, ink may have run out.
Replacing the ink tank is recommended.
If printing is in progress and you want to continue printing, press the OK button 
with the ink tank installed. 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 50.
NoteIf multiple ink lamps are flashing red, see “Getting the Ink Status Information” on 
page 50 and check the status of each ink tank.
“The following ink has run out. Replace 
the ink tank.”
U163Ink has run out. (The lamp on the ink tank flashes.)
Replace the ink tank and close the Scanning Unit (Printer Cover).
Printing under the current condition may damage the machine.
If you want to continue printing in this condition, you need to release the function 
for detecting the remaining ink level. Press and hold the Stop/Reset button for 
at least 5 seconds, and then release it.
With this operation, releasing the function for detecting the remaining ink level is 
memorized. Please be advised that Canon shall not be liable for any 
malfunction or trouble which may be caused by continuation of printing under 
the ink out condition.
See “Replacing an Ink Tank” on page 50.
NoteIf the function for detecting the remaining ink level is disabled, the ink tank in 
gray is displayed in the remaining ink volume screen on the LCD.
See “Getting the Ink Status Information” on page 50.
“Print head is not installed. Install the 
print head.”
U051
“The type of print head is incorrect. 
Install the correct print head.”
U052Follow the directions given in your setup sheet to install the Print Head.
If the Print Head is already installed, remove the Print Head once and then 
reinstall it.
If the error is not resolved, the Print Head may be damaged. Contact your 
Canon service representative.
“Inner cover is open. Close the inner 
cover and press OK.”If the Inner Cover is open when starting printing, close it and then press the OK 
button on the machine.
Do not open or close the Inner Cover while printing, as this can damage the 
machine.

color is installed.”
U071Possible causes are as follows:
zSome ink tanks are not installed in the correct position. (The lamp on the ink 
tank flashes.)
zMore than one ink tanks of the same color are installed. (The lamp on the ink 
tank flashes.)
Confirm that the ink tanks are installed in the appropriate positions.
See “Replacing an Ink Tank” on page 50.
 
						

							75 Troubleshooting
“The ink absorber is almost full. Press 
OK to continue printing. Contact the 
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 a Canon service representative as early as possible. (You will need to 
replace a particular part of the machine.)
“The device may be incompatible. 
Remove the device and check the 
manual supplied with the connected 
device.”zA communication time out occurs if an operation takes too long or if it takes 
too much time to send data. This may cancel printing. In such cases, 
disconnect and reconnect the USB cable.
When printing from a PictBridge compliant device, depending on the model 
or brand of your device, you may have to select a PictBridge compliant print 
mode on the device before connecting it to the machine. You may also have 
to turn on your device or select Play mode manually after connecting the 
device to the machine. Perform necessary operations before connecting your 
device referring to its instruction manual.
If the error is still not resolved, check if you can print another photograph.
zCheck your device connected to the machine. Only PictBridge compliant 
devices or the optional Bluetooth Unit BU-20 can be connected to the 
machine for direct printing. If a PictBridge compliant device is connected via 
a USB hub, remove the hub and connect it directly to the machine.
“Auto head align has failed. Press OK 
and repeat operation. ”Possible causes are as follows:
zPrint 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 57 and “Printing Does Not Start/Printing Is Blurred/
Colors Are Wrong/Straight Lines Are Misaligned” on page 80.
zPaper of size other than A4 or Letter is loaded in the Rear Tray.
Press the OK button on the machine to dismiss the error message, then load 
a sheet of A4/Letter-sized plain paper in the Rear Tray.
Automatic Print Head Alignment cannot be performed using paper from the 
Cassette. For Automatic Print Head Alignment, always load paper in the 
Rear Tray.
zThe 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 63.
“The remaining level of the following ink 
cannot be correctly detected.
Replace the ink tank.”
U130The remaining ink level cannot be correctly detected. (The lamp on the ink tank 
flashes.)
Replace the ink tank and close the Scanning Unit (Printer Cover).
Printing with an ink tank that was once empty may damage the machine.
If you want to continue printing in this condition, you need to release the function 
for detecting the remaining ink level. Press and hold the Stop/Reset button for 
at least 5 seconds, and then release it.
With this operation, releasing the function for detecting the remaining ink level is 
memorized. Please be advised that Canon shall not be liable for any machine 
malfunction or damage caused by refilled ink tanks.
See “Replacing an Ink Tank” on page 50.
NoteIf the function for detecting the remaining ink level is disabled, the ink tank in 
gray is displayed in the remaining ink volume screen on the LCD.
See “Getting the Ink Status Information” on page 50.
