Replacing Print Heads
The condition of the print heads directly affects the quality of printed models. You may need to replace a print head if one or more of the following symptoms occurs:
|
•
|
There are noticeable grooves in the surface of printed models. |
|
•
|
Visual inspection of the head reveals that its surface is damaged—peeling or bubbles in the nozzle area. |
|
•
|
The printer interface displays a warning or malfunction message relating to a print head— |
|
❒
|
Head Heater temperature timeout |
|
❒
|
Head Heater thermistor open |
|
❒
|
Head Heater thermistor short |
Replace print heads only after consulting with a Stratasys-authorized customer-support engineer.
The Head Optimization wizard guides you through the procedure of replacing a print head, and configures printer components to enable you to perform it. Only replace a print head with the aid of the wizard.
The entire print-head replacement procedure takes 75—90 minutes, and consists of the following phases:
|
A.
|
Identifying the head(s) needing replacement. |
This is normally done by the Head Optimization wizard. Otherwise, evidence of physical damage to the head surface or a malfunction message indicates which head needs replacing.
|
B.
|
Preparing the print block for head replacement. |
This is done automatically when you run the wizard.
|
E.
|
Optimizing the print heads (done automatically by the wizard). |
