Figure 7-25: Sample Pattern Test
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, more than 10
missing lines in one area of a column is considered unacceptable.
Improving
Print Quality
Ifyoususpectthatprintqualityispoor,performthepatterntest(see
“PatternTest”onpage 7‐21).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Execute 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”on
page 7‐19).
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:
