Automatic Black Ink Mode Switching
With both Photo and Matte Black ink cartridges installed simultaneously,
the Epson Stylus Pro 7900 and 9900 series printers automatically utilize
the optimal black ink mode, delivering maximum black density for the
chosen media. Taking advantage of the Epson MicroPiezo TFP auto-sharing
black ink channel ensures a fast and effi cient switch. And, to further
reduce switching errors, the user can now confi rm the switching process
from the front control panel.
The standard Photo Black ink mode can be used for any media type
with professional results. However, for certain Epson media types such
as Velvet Fine Art, Enhanced Matte and UltraSmooth
®
Fine Art, using
the Matte Black ink mode will dramatically increase your black optical
density for even better print quality.
