If 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 107.
Note
If multiple ink lamps are flashing red, see "Getting the Ink Status Information"
on page 107 and check the status of each ink tank.
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.
Follow 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.
Possible causes are as follows:
Some ink tanks are not installed in the correct position. (The lamp on the ink
tank flashes.)
More 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 107.
The 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 107.
Note
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.
See "Getting the Ink Status Information" on page 107.
