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
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 ‐ 22).
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:
¾
Replace faulty print heads (see “Replacing Print Heads” on page 7 ‐ 35).
Cleaning and
Replacing the
Wiper
A rubber wiper removes excess material from the print heads after the
purge sequence. This is done automatically before each print job, and
performed manually during maintenance tasks. You should clean the
wiper and surrounding area at least once a week. If the wiper is damaged
or worn, replace it.
To inspect and clean the wiper:
1. Prepare—
•
isopropanol (IPA—isopropyl alcohol) or ethanol (ethyl alcohol)
•
disposable cleaning gloves
•
an Objet ‐ supplied cleaning cloth or equivalent
•
a spare wiper
•
an M2.5 Allen key
