Printing Time

[Tamimi Siregar]

Hallo all,

I have a question regarding printing time.
I noticed that when I print using a nozzle for the complete printing, the approximation printing time given by the machine was actual.
But when I printing using 2 nozzles for the complete printing, the given approximation time was not actual but there is additional time after the first given approximation time. Also, the additional time given after finish first given approximation take longer time.
Could anyone let me know what is actually happen?

Regards,
Tamimi
