Ink in Ordung, unfortunately often wrong Chips

The ink quality is more for everyday use as well. However, the manufacturer or the seller does not pay attention to the coding of the chips on the cartridges. This should normally after the cartridge part number on the chip a "XL" are, because these chips are rated by the printer with "XL". Missing the "XL", the printer already (level yellow exclamation mark) reports after the first half of the filling, the cartridge is nearly empty and about one third has residual contents of the printer has corresponding "empty cartridge". Otherwise, I am very satisfied.
