7.1 CHANGING THE PRINT HEADS
WARNING: Do NOT touch or contaminate the gold contacts on either the print heads or the
carriage with your fingers. Avoid spilling binder on the contacts. If you do get binder or anything
else on the gold contacts, clean them with an alcohol swab.
The print head will need to be changed when the print becomes uneven. A print head should
be able to print at least 1.2 liters of binder (about 30 Billion pixels, equivalent to about 2500
cubic centimeters of parts). Print head life can depend upon the geometry of the parts printed,
so some print heads may last longer. Signs of a worn print head are weak parts, rough surface
finish, or visibly uneven printing in the build. The software will display a warning when the print
heads will be exceeding the expected print head life during the build.
To ensure that the build will be completed and good print quality replace the print heads (Z
Corp. part number 13524) as follows:
1. The printer should be online. From the
‘Service’ menu, select ‘Change Print
Head’.
2. Press the ‘Start’ dialog box button to
begin the process. The front panel lights
will flash rapidly and the gantry and
carriage will move into position.
3. Wait for the printer to finish moving and
the front panel lights to change to slowly
blinking. This indicates that it is safe to
remove the print heads from the carriage.
4. Lift the carriage cover.
Technical Tip –
If you need to work in another dialogue box,
click the close window button (X located on
the upper right-hand corner), NOT THE DONE
OR CANCEL button. You may continue
changing print heads. Complete the procedure
by pressing the ‘Online’ button on the printer
when complete.
