Ink Optimizer and the selected media
The Ink Optimizer is a special fluid which ensures that black and colour
inks bond completely with the surface of Plain Paper and envelopes making
the printed text water-resistant. Here are two important points you should
keep in mind about the Ink Optimiser.
■ The Ink Optimizer is enabled and operates only when Plain Paper or an
envelope size is selected for the Media Type with the printer driver. Plain
Paper must be selected for standard photocopier paper, bond paper,
Bubble Jet Paper LC-301, and Banner Paper (the composition of Bubble Jet
Paper LC-301 and Banner Paper is the same), and envelopes must be
selected for US Commercial No. 10 or European and DL envelopes. If
any media other than Plain Paper or an envelope size is selected for the
Media Type (Transparency, Fabric Sheet, High Gloss film, Glossy Photo
Paper, Glossy Photo Cards, etc.), the Ink Optimizer is automatically
turned off and will not operate.
■ Even if you have selected Plain Paper or envelope size for the Media
Type, the Ink Optimizer will not operate if you select Fast with the slide
bar for Print Quality.
