How the WorkCentre 7970 ColorMultifunction Printer Exceeds thePrint Quality RequirementColor Registration and AccuracyWith an ASIC driver to control the light intensityof the LEDs in each printhead, HiQ LED offersbetter dot-to-dot intensity and timing control,and produces more precise color registration.HiQ LED handles mis-registration issuesautomatically, simultaneously and continuously,from LED to LED. In fact, tests show that HiQLED technology corrects color mis-registrationeven better than comparable laser printers.Plus, true Adobe ® PostScript ® 3 ™ , PCL ® andXPS give you the power to print visually richdocuments reliably.Printhead Technology and Image ResolutionThe WorkCentre 7970 Color MultifunctionPrinter features the Xerox ® HiQ LED printhead,which offers major improvements in imagequality.The “brain” behind the entire print-head processis our new application specific integrated circuit(ASIC) driver chip. This high-performance driverprecisely controls the intensity and timing LEDsin each printhead to achieve 1200 x 2400 dpiresolution – print quality that’s equivalent to,and often better than, comparable laser systems.By continually and automatically monitoringinformation about each LED, the ASIC driver canadjust each diode’s light intensity and timing.This ensures uniformity across the entire LEDarray – and produces consistently high printquality without compromising the printer’s high-speed output. Whether printing spreadsheets,presentations or customer collaterals, theWorkCentre 7970 delivers truly impressive results.Plus, Xerox ® EA Ultra Low-Melt Toner –chemically grown to produce the market’ssmallest, most uniformly shaped particles –delivers sharper clarity, excellent shadowingand outstanding fine-line detail.Unique Color ControlOur “Color By Words,” a powerful-yet-intuitivecolor technology, takes the guesswork out ofoptimizing your color print jobs. With Color ByWords there is no need to manipulate sourcefiles. Users simply select the desired colormodifications from a drop-down list – such as“green colors a lot more green” or “red colorsa lot more saturated” – and the image isautomatically adjusted.Section 2: Evaluating WorkgroupColor Multifunction PrintersPrint QualitySolid Performance.
