Adjusting a Single Dot Diameter C9
This function allows you to change the dot diameter of individual dots from top to bottom by altering the stroke, in
microseconds, of a piston in an ink channel. When the dots in a row are too small, they require a dot-size increase. If
they are too large, they require a dot-size decrease.
Changing individual dot diameters requires a menu that is available only after a special initialization. Start by unplugging
the I.V./700.
1 Press and hold ALT+INFORMATION.
2 Plug in the barrel connector.
3 Release the keys when the LCD shows
“Information.”
4 Press SET-UP
5 Press J on the QWERTY keypad. The LCD will
prompt for the number of the dot that is not printing
like the other dots. The top dot on the printhead is
dot number 1 and the bottom dot is dot number 7.
6 Scroll to the number of the problem dot.
7 Press ENTER.
8 The LCD will prompt for a new diameter of the
selected dot. Move to the second digit (250) and
scroll to a new value. The scroll changes by units of
10.
9 Press SET-UP. The LCD will ask if you want to keep the “Factory Setting Y/N?” Select “1-NO.” When you select
NO, the I.V./700 remembers the new dot pulse width value only until the next initialization.
By running print samples and altering pulse-width values, you can change a single dot until it matches the other
dots.
10 When you achieve the best print, select “2-YES” when exiting this function. This choice makes the new pulse width
value permanent.
The scanned samples below show the changes in appearance of a single dot with different diameters.
