6. Carefullyinspectthetestpapertoseeiftherearemissinglines.
Toomanymissinglines,especiallyiftheyareinthesamearea,
indicatesthatthequalityofprintingwhenproducingmodelswillbe
poor.Ifthisisthecase,see“ImprovingPrintQuality,”below.
Note: Acceptable model quality is subjective, and depends on the type
and scale (size) of the models produced. As a rule, however, if two
consecutive lines are missing, or if there are more than 10 lines missing in
either column, the model quality is usually unacceptable.
Improving
Print Quality
Ifyoususpectthatprintqualityispoor,performthepatterntest(see
“PatternTest”).Iftheresultsarepoor,usethefollowingprocedureto
improveprintquality.
If the results of the last pattern test are poor:
1. FromtheOptionsmenu,selectPurge Sequence,orpressF4.
2. Intheconfirmationdialogbox,clickYes.
TheprintheadsarepurgedofModelandSupportmaterial,andthe
wiperremovesexcessmaterialfromthem.
3. Repeatthepurgesequence.
4. Performthepatterntest.
If the results of the pattern test are still poor:
1. Manuallycleantheprintheads(see“CleaningthePrintHeadsandthe
Roller”onpage 19).
2. Performthepurgesequence.
3. Performthepatterntest.
If the results of the pattern test are still poor:
1. Carefullycleantheprintheadsagain,makingsurethereisnoresidue
leftonthem.
2. Performthepurgesequence.
3. Performthepatterntest.
If the results of the pattern test are still poor:
Optimizetheprintheadsandreplacefaultyprintheads,ifnecessary(see
“Optimizing(Calibrating)PrintHeads”onpage 30).
