Oi,
Infelizmente, não é possível imprimir usando o preto e branco enquanto qualquer um dos cartuchos estiver vazio.
Usar a tinta preta somente é possível enquanto houver tinta colorida.
While the color ink is not required for prinitng purposes, it do required for ,maintnance operations of the device.
As the device contain an internal printhead (IIC system), lack of color ink will damage the printing system shortly. Therefore the device will not be functional when there is no ink in order to avoid damaging the system.
For users who wish to print using just black ink (despite the reduced print quality), many HP printers offer options. For example, a driver colour setting (by selecting "print in greyscale with the black cartridge only" in printing preferences) specifies printing using only black ink. In addition, many IPH printers can operate in "reserve mode", which allows the user to continue to print with just the black cartridge when the colour cartridge is removed or not installed.In HP IIC systems, all supplies are required to be installed in the printer for the printer to function
