UV Bulb Expectations For HP Scitex FB910 (ColorSpan 9840uv) and ColorSpan Legacy UV Printers 1
Introduction Many customers have questions about the bulbs for the UV-curing lamps on the UV series of printers. This document defines the factors that contribute to bulb wear and what to expect from your UV system. Terminology The UV lamp system consists of these parts: Lamp Housings The two ventilated boxes on the left and right sides of the carriage. Each lamp housing is conceptually equivalent to a light fixture in your home or office: it is a reasonably permanent hardware item.
1. Increase power from low to medium, and then from medium to high. Increasing the power setting causes the bulb to emit more UV energy. Heat output will increase as well, so see the section below about power settings and heat generation. 2. Change to the next slower print mode. Each mode moves the media through the lamp zone at a different rate. Slower print modes allow the printed ink to be exposed to the decreased lamp energy more times, resulting in an accumulation of enough UV energy to cure the ink.
