Replacing an Ink Tank 
W hen remaining ink cautions or errors occur, the Alarm
 lamp will flash orange to inform you of the error.
Refer to Four flashes: of Alarm Lamp Flashes Ora nge in 
Troubleshooting of the on-screen manual: 
Advanced Guide , and take an appropriate action.

 For information on the compatible ink tanks, refer  to the printed manual: Getting Started.

 Replacing Procedure 
W hen you need to replace ink tanks, follow the proc edure below.
 Important
Handling Ink
 If you remove an ink tank, replace it immediately. Do not leave the printer with ink tanks removed.
 Use new ink tanks for replacement. Installing used  ink tanks may cause the nozzles to clog.
Furthermore, with such ink tanks, the printer will  not be able to inform you when to replace the ink
tanks properly.
 Once an ink tank has been installed, do not remove  it from the printer and leave it out in the open.
This will cause the ink tank to dry out, and the pr inter may not operate properly when it is
reinstalled. To maintain optimal printing quality,  use an ink tank within six months of first use.
 Note
 Color ink may be consumed even when printing a bla ck-and-white document or when black-and-
white printing is specified.
Every ink is also consumed in the standard cleaning and deep cleaning of the Print Head, which
may be necessary to maintain the printers performa nce. W hen an ink tank is out of ink, replace it
immediately with a new one.
