IBM CF Series manual F Resolution Control, 31 Resolution Control Display

5.1.15 (F) RESOLUTION CONTROL

The option is used to set scanning resolutions and their corresponding display strings. Resolutions are selected by a letter index A-H. The number of resolutions that appears is governed by the number set in the Global Parameters.

When you press <F> to select “Resolution Control”, the display on the screen will be similar to figure 5-31.

	----- RESOLUTION CONTROL -----
RESOLUTION	PIXELS/INCH	DISPLAY STRING	DIVISOR
----------	-----------	--------------	-------
A	1000	1000	1.000
B	800	800	1.250
C	700	700	1.430
D	600	600	1.665
E	500	500	2.000
F	400	400	2.500
G	300	300	3.335
H	200	200	5.000
	S : SET RESOLUTION	X : EXIT

CHOICE : X

The Resolution Index (A-H) is a common index used to relate a set of parameters: resolution control, motor speed, and the splice count, together.

“Pixels/inch” is the number of pixels the scanner can resolve per inch.

“Display string” is the name you assign to each Resolution Index and it is display on the keypad display window as well as on the Main Menu of the local control terminal.

“Divisor” is the ratio of maximum resolution to scanning resolution. For example, a CF1000 scanner has a maximum resolution of 1000 pixels/inch. If scanning resolution is 500 pixels/per inch, the divisor is (1000.0)/(500.0) = 2.000. Calculate the required divisor values in this way before setting new resolutions.

If you press<X> for “Exit”, you will be returned to the Diagnostic Test menu.

If you press <S>, the prompt “Resolution” appears, enter a letter for the resolution you wish to set.
