	Canon recommends to use new genuine Canon cartridges in order to obtain
	optimum qualities.
	Please be advised that Canon shall not be liable for any malfunction or trouble
	caused by continuation of printing under the ink out condition.
CHECK INK	Ink has run out.
U163	Replace the ink cartridge and close the Scanning Unit (Printer Cover).
	If printing is in progress and you want to continue printing, press the Stop/Reset
	button for at least 5 seconds with the ink cartridge installed. Then printing can
	continue under the ink out condition.
	The function for detecting the remaining ink level will be disabled.
	Replace the empty ink cartridge immediately after the printing. The resulting
	print quality is not satisfactory, if printing is continued under the ink out
	condition.
REQ. SERVICE SOON	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.)
INCOMPATIBLE CAMERA	A 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.
UNSUPPORTED USB HUB	If a PictBridge compliant device is connected via a USB hub, remove the hub
	and connect it directly to the machine.
