Aligning the
Print Heads
You should check the alignment of the print heads—
• once a month
• after replacing one or more heads
• if model quality is not acceptable even after cleaning the orifice plate on
the bottom of the print block (see "Cleaning the Print Heads and the
Roller" on page 6-26).
This procedure takes about 20 minutes.
To check the alignment of the print heads:
1. Prepare—
❒
a transparency sheet—A-4 or Letter size
❒
any type of adhesive tape, to fasten the transparency sheet to the build
tray
2. Start the Head Alignment wizard from the
Options
menu.
3. Click
Next
to begin, and close the cover.
4. In the wizard screen, select the check box to confirm that the cover is
closed, and click
Next
.
5. When instructed to do so, place the transparency on the build tray— next
to the left and rear edges of the tray, as shown in the following figure.

6. Make sure that the transparency sheet is lying flat, and tape it to the tray.
7. In the wizard screen, select the check box to confirm that the
transparency sheet is on the build tray, and click
Next
.
The printer prints the head alignment test on the transparency.
