Close the ink cartridge cover. 
 Do not turn off the power or open the ink cartridge cover while the power LED is 
flashing. These actions make the ink be charged again, which results in a noticeable 
consumption of ink. In addition, there is a risk that you will not be able to print properly. 
 If the ink cartridges are not recognized even though they are set properly, dirt may be 
stuck on the green IC chip surface. Wipe it off with a soft cloth, and then set it again. 
 If you cannot print even though the ink cartridges are set properly, run print head 
cleaning. See “Cleaning the print head” on page 133 in this guide for head cleaning 
procedure. 
 If you turn the power off using the power button on the unit, the print head is 
automatically capped, which prevents the ink from drying. After installing the ink 
cartridges, be sure to turn the power off using the power button on the unit when you 
are not using the product. Do not pull out the power plug or trip the breaker while the 
power is on.
 If you move or transport this product after you have installed the ink cartridges, leave 
the ink cartridges as they are when you move or transport it. 
 Do not take out the ink cartridges unless you are replacing them.
