Microfine High Definition Toner & ProQ2400 Multilevel Technology
High quality colour output is essential if a business is to present a professional image. OKI Printing Solutions developed microfine High Definition Toner in tandem with the ProQ2400 Multilevel print heads, to produce high definition print quality.
What is microfine High Definition Toner?
Microfine High Definition Toner is physically smaller than previous toner. Building on the OKI Printing Solutions heritage of colour printing innovation, microfine High Definition Toner colour printing technology combines multilevel LED printheads and microfine toner to render deeper more saturated colours, finer detail, and more precise toner
What does microfine High Definition Toner do?
Microfine High Definition Toner helps to ensure clean, crisp text & excellent output. In conjunction with ProQ2400 Multilevel Technology, this makes placement on the page more accurate allowing for;
• greater glossiness and;
• reduced graininess
What is ProQ2400 Multilevel Technology?
ProQ2400 is an intelligent digital image processing technology from OKI Printing Solutions, producing subtler tones and smoother gradations of colour for impressive print quality results. ProQ2400 Multilevel Technology provides the ability to apply different levels of intensity of LED light energy when creating each and every printed dot, so varying the amount of toner placed on each dot.
• ProQ 2400 = 600 x 600 dpi with multi bit heads (Found on C3000, C5000, C9600 only)
• ProQ 4800 = 1200 x 1200 dpi with multi bit heads (Found on C9800 only)
How does ProQ2400 Multilevel Technology work?
The general goal in colour printing is to simulate an analogue device such as camera film, monitors, scanners. These devices provide the greatest range of colour, or shades of grey (See figure 1.0).

Traditional printers apply dots using 2-levels of intensity: 100% black or 100% white. Dots are grouped together (creating halftone cells) to simulate levels of grey.
Here are examples of grey shading using 3x3 printer dots in a halftone cell.

ProQ2400 Multilevel Technology can produce different levels of intensity. What is produced is a halftone with a range of levels between ON and OFF - similar to the effect you get when replacing a standard light switch with a dimmer.

ProQ2400 Multilevel Technology delivers more shades of grey or colour within the same size halftone cell. This results in a higher level of detail and greater colour depth, another great feature from OKI Printing Solutions.
Where can I find the ProQ2400 MultiLevel Technology feature?
Go to the printer driver dialogue box which can be found by going the 'Print' dialogue box, and clicking on the 'Properties' tab. Select the 'Job Options' tab and click on 'ProQ2400'.
