108 | Maintaining and Transporting the Printer
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 Menu 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 Menu 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.
Replacing Ink Cartridges
Before you begin a large print job, you should check your ink levels. If one of
your cartridges is low, you can replace it before you start. Or you can wait
until the ink runs out, replace the cartridge, and then continue the job
without any loss of print quality. However, it is best to replace a low ink
cartridge before starting a large print job.
