Operating & Maintaining the Connex500/350 3D Printer
Calibrating
(Optimizing)
Print Heads
6–38
The condition of the print heads directly affects the quality of printed
models. To maintain optimum printing, you should test the print heads,
and calibrate them to the best working configuration possible every 300
hours of printing. You should also perform this procedure...
•
whenever you suspect that the condition of print heads is negatively
affecting the quality of printed models
•
if there is a problem with one or more of the print heads
•
after replacing a print head
The print head calibration procedure consists of the following phases:
A. Cleaning the print heads.
B. Printing calibration samples—eight patches, each representing a print
head.
C. Examining and weighing the patches, and entering this data in a
separate utility (the Head Calibration Utility) that calculates how to
calibrate the print‐head settings.
D. Saving the new print‐head settings.
E. Repeating the process, as required, until the print heads calibration is
optimal.
Note: This procedure can take between 30–120 minutes, depending on the
condition of the print heads and the number of iterations required. If
a print head cannot be calibrated for acceptable printing, the head
calibration utility instructs you to replace it.
To clean the print heads:
Refer to "Cleaning the Print Heads and the Roller" on page 22.
To accurately test and calibrate the print heads, they must be clean.
