Figure 6-29: Sample Pattern Test
6. Carefullyȱinspectȱtheȱtestȱpaperȱtoȱseeȱifȱthereȱareȱmissingȱlines.ȱ
Tooȱmanyȱmissingȱlines,ȱespeciallyȱifȱtheyȱareȱinȱtheȱsameȱarea,ȱ
indicatesȱthatȱtheȱqualityȱofȱprintingȱwhenȱproducingȱmodelsȱwillȱbeȱ
poor.ȱIfȱthisȱisȱtheȱcase,ȱseeȱ“ImprovingȱPrintȱQuality,”ȱbelow.
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
Ifȱyouȱsuspectȱthatȱprintȱqualityȱisȱpoor,ȱperformȱtheȱpatternȱtestȱ(seeȱ
“PatternȱTest”ȱonȱpage 25).ȱIfȱtheȱresultsȱareȱpoor,ȱuseȱtheȱfollowingȱ
procedureȱtoȱimproveȱprintȱquality.
If the results of the last pattern test are poor:
1. FromȱtheȱOptionsȱmenu,ȱselectȱPurge Sequence,ȱorȱpressȱF4.
2. Inȱtheȱconfirmationȱdialogȱbox,ȱclickȱ
Yes.
TheȱprintȱheadsȱareȱpurgedȱofȱModelȱandȱSupportȱmaterial,ȱandȱtheȱ
wiperȱremovesȱexcessȱmaterialȱfromȱthem.
3. Repeatȱtheȱpurgeȱsequence.
4. Performȱtheȱpatternȱtest.
If the results of the pattern test are still poor:
1. Manuallyȱcleanȱtheȱprintȱheadsȱ(seeȱ“CleaningȱtheȱPrintȱHeadsȱandȱtheȱ
Roller”ȱonȱpage 20).
2. Performȱtheȱpurgeȱsequence.
3. Performȱtheȱpatternȱtest.
If the results of the pattern test are still poor:
1. Carefullyȱcleanȱtheȱprintȱheadsȱagain,ȱmakingȱsureȱthereȱisȱnoȱresidueȱ
leftȱonȱthem.
2. Performȱtheȱpurgeȱsequence.
3. Performȱtheȱpatternȱtest.
If the results of the pattern test are still poor:
