Replacing Procedure
When you need to replace an ink tank, follow the procedure below.
 Important
Handling ink
 If you remove an ink tank, replace it immediately. Do not leave the printer with the ink tank removed.
Use a new ink tank for replacement. Installing a used ink tank may cause the nozzles to clog. Furthermore, with such an ink tank, the printer will not be able to inform you when to replace the ink tank 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 printer 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 black-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 and in the system cleaning, which may be necessary to maintain the performance of the printer. When an ink tank is out of ink, replace it immediately with a new one.
