Component Usage
One cycle is counted when the Carriage makes one movement to the left of
the Printer and then returns to the right.
îš„ Tube used with non-HP ink: This is set to Yes as soon as the Printer
detects that at least one Ink Cartridge was used with third-party ink. This
cannot be reset to No (because it is part of the ISS EEROM), except
when:
– The Ink Supply Tubes are replaced (not under warranty).
– The Printer detects that the Ink Cartridge being used no longer uses
third-party ink.
