You can continue to use the product even if one or more ink tanks are not filled all the way. However, for
the most accurate ink level monitoring, fill all the ink tanks up to the top line.
Note:
The product has a low ink alert system. The accuracy of this system depends on the user refilling
the ink tanks correctly. The product cannot directly measure the ink levels in the tanks; instead it
estimates the amount of ink remaining by internally monitoring ink usage. The low ink alert system may
generate inaccurate messages if the ink tanks are not refilled according to these instructions.
As a precaution, perform regular visual inspections of the ink tanks to ensure ink levels do not fall below
the lower line. Continued use of the product when the ink level is below the lower line on the tank could
damage the product.
Caution:
Wear disposable gloves while refilling the ink tanks to avoid staining your hands. If ink spills,
wipe it off immediately with a damp towel to avoid permanent stains. If ink gets on your clothes or
belongings, it may not come off.
