A sticker must remove the one is color-coded and it should not expect too must draufstehen
"Please before inserting unregistering, otherwise ink may leak, due to the slight overpressure in the Partone" ...
Who expects such a text in such a small color cartridge, which would also Maci sue because the coffee too hot and no "Attention - hot !!" Imprint on the cup is available.
Or perhaps the insertion of a color cartridge for some is a real challange.
Who needs to print a lot of tables, text etc ... SW which I can recommend only.
Ignore the negative reviews ... are also only human can not help it
