Calibrating
Print Heads
Theconditionoftheprint headsdirectlyaffectsthequalityofprinted
models.Tomaintainoptimumprinting,youshouldroutinelytesttheprint
heads,andcalibratethemtothebestworkingconfigurationpossible.You
dothisbyrunningtheHeadOptimizationWizard.
If,duringtheoptimizationprocess,thewizarddeterminesthat
aprinthead
isfaulty—orthatitisnegativelyaffectinglayeruniformitywiththecurrent
headconfiguration—thewizardinstructsyoutoreplaceit.Ifthishappens,
youcancontinuethewizard(toreplacetheprinthead)orabortthewizard
(toreplacetheheadatanothertime).
Note: Allow at least three hours for performing this procedure (not
including time required for replacing faulty print heads).
Toaccuratelytest
andcalibrateprintheads,theymustbeclean.If
necessary,runtheHeadCleaningWizardbeforebeginningthisprocedure.
To test and calibrate the print heads:
1. Prepare—
• disposablecleaninggloves
• thescalesuppliedbyObjetforuseintheWeightTest
Run the Head Optimization Wizard whenever the condition of print heads is
negatively affecting the quality of printed models, or if you suspect that there
is a problem with one or more of the print heads.
