Maintaining and Transporting the Printer

7. Press the

button to display

AUTO

, then press the

button again. You see

UNI-D

(uni-directional). This is the type of

alignment to start with.

8. Press the

button again to start the alignment process.

It takes about 7 minutes to run the automatic uni-directional head
alignment. The printer’s white beam sensor reads the alignment pattern
and adjusts the printer automatically. Make sure you don’t open the top
cover or turn off the printer during this process.

9. When the uni-directional alignment is finished, press the button until

you see

BI-D 2-COLOR

. Then press the

button again to start

the bi-directional black alignment process, which is also completely
automatic and takes about 7 minutes.

10. When the bi-directional black alignment is finished, press the button

until you see

BI-D ALL

. Then press the

button again to start

the alignment process. Again, this process is completely automatic and
takes about 7 minutes.

11. When done, press the

Pause button to exit the head alignment mode.

If you want to verify or fine-tune the automatic alignment process, you can
perform a manual head alignment. See your electronic Reference Guide for
instructions.
