11.2.3. Carriage Speed:
The engine has got 3 pre-defined Carriage speeds: 750, 1

135 and 1625.
Intermediate speeds are not possible; These speeds were selected on the physical
characteristics of the inkjet heads
.

750 as the default speed for white ink printing750 as the default speed for white ink printing
750 as the default speed for white ink printing (remember: the
white ink is jetted with another kind of head with other characteristics).
The higher speed 1625 is only there to make color prints (without white) in
circumstances where quality is of less importance then speed; Printing white in
this mode is totally impossible.
This speed can be a way out if you have a heat sensitive media and have to limit
the time that the media will get the warmth of the UV-lamps over it.
Printing white at the higher speed of 1135 instead of 725 will result in a too high
spray of white ink and nozzle drop-out.
A Uni-directional print is faster than twice the time of the same image printed
bidirectional. This because the return speed (movement from purge to home)
occurs not onto the selected speed (725 or 1135 or 1625) but on a higher fixed
speed of 1700.
As a result, you don’t loose half your Bi-dir speed when printing Uni-directional.
When you’ve selected another speed, you have to do a ‘Save

Save’ to store the new
parameter into the list, BUT YOU ALSO have open the ‘Test’ menu and execute a
‘Parameter download’
Parameter download’Parameter download’
Parameter download’. Without doing that, the new selected speed will not be
taken in account in the next prints.
11.2.4. Feed Speed:
This is the speed of the forward moving of the conveyor belt in-between the print
passes.
A Feed Speed of “250” is considered as the default to give you the most accurate
feeding. Higher values up to 500 are possible and will only in bidirectional print
mode result in a small increase in productivity (no effect on unidirectional mode),
but with a higher possibility to have inaccurate steps (banding) due to slip of the
media.
This parameter is fixed by the technician and not accessible to the user.
