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, result- ing in an accumulation of enough UV energy to cure the ink.

At some later time, the energy output even at the high power setting combined with printing in the slowest mode will not expose the ink to enough UV energy to cure. At this point there is no option except to replace the bulbs. The estimated maximum life for a bulb is 1000 hours.

Additional Notes on Bulb Life

•“On-time” includes all time that the bulbs are on, including when the printer is not actively printing. The set- ting for idle on-time until automatic shut-off can be adjusted between 1 and 8 minutes.

•On-time alone is not the only factor that contributes to eventual energy decline. Each startup cycle of the

bulb also contributes to the decline. To maximize bulb life, plan your printing schedule so that both idle on-time and lamp startup/shutdown cycles are kept to a minimum.

•Using the manual media measurement method, whereby the printer operator finds the width of the media by manually positioning the carriage over each edge, must turn off the lamps in order for the measurement to take place. This increases the number of startup cycles, which as noted above contributes to decreased bulb energy.

Bulb Power Settings and Heat Generation

Some customers have observed an increase in “Lamp Overheated or Disconnected” error messages after changing the bulb power setting to Medium or High. Each lamp assembly has a cooling system consisting of two fans that pull air through the top of the lamp housing, blow it over the bulb, and expel it out the side of the housing. The top of the assembly has a filter screen that keeps foreign particles from being blown by the fans onto the bulbs. This filter screen can become clogged, decreasing the air flow over the bulbs and therefore decreasing the efficiency of the cooling system. The Medium and High power settings create more heat than the Low power setting, and so if the cooling system is operating at anything less than peak efficiency, the temperature could exceed the safety limit and cause the lamp to turn off.
