The print yield in the table above is an average value measured in continuous printing, using the ink tank immediately after it is unsealed, until the ink is out. Ink yield may vary depending on texts and photos printed, application software, print mode, and type of paper used.

When the machine is turned on and while printing, each ink may be used for protecting the print head and maintaining print quality.

LIST OF ERROR DISPLAY / INDICATION

Errors and warnings are displayed by the following ways:

Operator call errors are indicated by the Alarm LED lit in orange, and the error and its solution are displayed on the LCD in text and by icon.

Warnings during printing from a computer are displayed on the printer driver Status Monitor.

Error codes are printed in the "operator call/service call error record" area in EEPROM information print.

Buttons valid when an operator call error occurs:

An ink tank which has once been empty is installed. Replace the applicable ink tank with a new one.

Printing with a once-empty or refilled ink tank can damage the print head.

If printing is continued without replacing the refilled ink tank, press the Stop/Reset button for 5 sec. or longer to record the use of a refilled ink tank.

Note:

After the above operation, the function to detect the remaining ink amount is disabled.

A non-supported ink tank is installed (the ink tank LED is turned off). Install the supported ink tanks.

Handle the problem based on the investigation and test results.

Memo: If a trouble occurs in communication with a non-Canon machine, and if a Canon machine operates properly without any problems,

it is recommended to let the user understand that the non-Canon machine needs to be examined accordingly. Since the cause of the trouble may exists in communication ability of the machine, contact a relevant service contact point of a non-Canon machine. In such a case, the information obtained in step 1) will be a help for quick solution to the problem.
