Remove Data from Information Only Fields (IO)


You can remove data from information only fields that you have previously populated either in scanning or with an IO or IA LFP file command. To do this, simply load an LFP file with the IO command, and do not provide any information after the field number.

Command Structure

IO,[Image Key],[Information Field Number],[leave information empty]



Important: Be sure to supply the comma after the IO field number. See the highlight in the example below.


Command Elements

Function or target



The identifier that tells the system this is an information field import process.

[Image Key]

The image key from which the information field data is to be deleted.

[Information Field Number]

The field number assigned to the information. Valid information field numbers are 1, 2, 3, 4, 5, 6, 7, 8, 9, and 10. You can use a single file to load multiple fields into the same image key. You must have a separate record for each information field number.


This is blank. Because the IO command overwrites any existing data for the field, overwriting any existing data with nothing essentially deletes the previous contents of the IO field.

Important: Be sure to supply the comma after the IO field number.
