Whencalibratingthelamps,thewizardattemptstoadjusttheradiation

isacceptable,thewizardcontinuestothenextphase.Iffurtheradjustment
isnecessary,thecurrentphaseisrepeated.Ifthelevelistoolowtobe

indicatesthatthelamp’sradiationfortheprintingmodeisunacceptable.
To test and calibrate UV lamp radiation:
1. StarttheUVCalibrationwizardfromtheOptionsmenu(seefigure 7‐26
onpage 23).
2. Makesurethatthebuildtrayisempty,theUVsensorisexposedand
clean,andthattheprintercoverisclosed.Confirmthisinthewizard
screenandclick
Next.

TheUVlampspowerupandstabilize;thistakesseveralminutes.Then,
theprintblockpassesoverthesensor.
Thewizardcomparesthemeasuredradiationtotherecommended
levelforthelampandprintingmodetested,anddisplaystheresult.
Thewizardcontinuesasfollows:
• Ifthelevelmeasuredintheprevioustestisacceptable,thewizard
beginstestingtheleftUVlamp.
• Ifthelevelmeasuredintheprevioustestisnotacceptable,the
wizardcalibratestherightUVlampbyadjustingthecurrent
suppliedtoit,thentestsitagain.
• Ifthelevelmeasuredintheprevioustestistoolowtobeadjusted,
thewizardrecordsthelamp’sradiationasunacceptable,andbegins
testingtheleftUVlamp.
