History
Modifications from Ver.1.32
- In case the nozzles are clogged, formerly you would stop printing and check the printout, and then continue printing by pressing the Online key. 
Now it automatically checks the level of clogging, and if it is possible to print it will continue printing, and if it needs a printhead replacement, it will display a Replace Printhead message.
This modification will greatly improve the workability.

Automatic Band Adjustment might have been failed. This problem has been fixed.
