Ink intensity and light resistance has improved. The new ink tank (BCI-6) is not interchange-
able with the BCI-5. (The BCI-6 can be used in the BJC-8200 if the printer driver is upgraded to

Compared to the BC-50, the frequency of ink ejection is high.
The new head can be used in the BJC-8200 but the BC-50 cannot be used in the S800.
If a BC-50 is installed in the S800, a head error will occur.
The new head is a service part, part number QY6-0035-000.
