The message is displayed on the LCD when you start printing.
Obtain a new ink tank.
zTo continue printing, select  and then press [OK].
zTo cancel printing, select  and then press [OK].
When Ink has Run Out:   is displayed.
zPress [OK] to resume printing with an empty ink tank. When printing is finished, replace the ink 
tank immediately. If you continue printing with an empty ink tank, it will be a cause of trouble.
* Printing does not resume if any of the ink tanks are left uninstalled. Be sure to press [OK] with 
all the ink tanks installed.

Replacing Ink Tanks
When an ink tank runs out of ink, replace it using the following steps.
Note
zTo maintain optimal print quality, use an ink tank within six months of its first use.
zOnce an ink tank has been used, do not remove it from the machine and leave it out in the open. 
This will cause the ink tank to dry out and the machine may not operate properly if it is reinstalled.
zColor ink consumption may occur even when black-and-white or grayscale printing is specified.
Color ink is consumed in the head cleaning and deep cleaning, which are necessary to maintain 
the machine’s capabilities.

Keeping the Best Printing Results
zWhen unplugging the power cord
When unplugging the power cord, be sure to press [ON/OFF] first. When you press [ON/OFF], 
the Print Head is protected by the cap to prevent the ink from drying. When unplugging the 
power cord, be sure to unplug it after turning OFF the machine with [ON/OFF].
zWhen not using the machine for a long time
When not using the machine for a long time, print or copy in both black & white and in color, or 
perform Print Head cleaning, about once a month to prevent degradation of the Print Head.
Numerous nozzles are installed in the Print Head for high-precision printing. Just as the 
uncapped tip of a ballpoint pen or marker becomes dry and unusable if not used for a long period 
of time, the Print Head nozzles become blocked by dried ink. Periodically printing or cleaning the 
Print Head can prevent this blockage.
Note
Ensure that the Inner Cover is closed. Printing will not occur if the Inner Cover is open.
Caution
zBe sure to hold the Scanning Unit (Printer Cover) firmly using both hands, and be careful 
not to get your fingers caught.
zDo not hold the LCD.
Note
zIf  is displayed on the LCD after the Scanning 
Unit (Printer Cover) is closed, some ink tanks may be installed in the wrong positions. 
Open the Scanning Unit (Printer Cover) and make sure that all the ink tanks are installed in 
the correct order directed on the label.
zWhen you start printing after replacing the ink tank, the machine executes Print Head 
cleaning automatically. Do not perform any other operations until the Print Head cleaning 
finishes.
Note
If the printed area is traced with a highlight pen or paint-stick or stained with water or sweat, 
ink may blur depending on the paper.

When Printing Becomes Faint or Colors are Incorrect
When printing becomes faint or colors are incorrect, even if ink remains in the ink tanks, the Print 
Head nozzles are probably clogged. Follow the procedures below to clean the nozzles.
If the ruled lines are shifted after running the Print Head maintenance, align the Print Head.
zIf the ruled lines are shifted
Note
Before printing the nozzle check pattern or cleaning the Print Head, check the following;
– Open the Scanning Unit (Printer Cover), and make sure that all the ink tanks click into place and 
then their lamps light red.
– If any one of the lamps is flashing, the associated ink tank is empty or running low. See “Getting 
the Ink Level Information” on page 108.
If an ink tank lamp is flashing even though ink remains in that ink tank, it is inserted in the wrong 
position. Make sure that the correct ink tank color is inserted in each position. Open the 
Scanning Unit (Printer Cover) and make sure all the ink tank lamps are lit. See “Replacing an 
Ink Tank” on page 108.
– If the ink tank lamp is unlit, press the   mark on the ink tank firmly until it clicks to fully insert 
it. Make sure that all packaging material is peeled off the ink tank. See “Replacing Ink Tanks” on 
page 109.
