10-F EA Mode (Variable Length Output Command for Automatic Density Distinction)

[Explanation]

The data format is the same as the one in the E mode.

This command is for automatically distinguishing mark density for one column. When there are

several marks, it cancels light-colored marks of larger density difference than the set difference and

outputs marks of smaller density difference than the set difference. Since the density difference is set

at 01 by default, the darkest mark data is output in this case. Density difference between a dark mark

and the next darker mark to be canceled can be set using the DC3 DD command.

Separators like STX and ETX can be added using the DC4 command.

Note: Relationship with sensitivity level setting

When there is only one mark, the existence of a mark is distinguished according to the

preset sensitivity level.

When there are several marks, density differences are compared among marks of density

more than the preset sensitivity level.

Marks of density less than the preset sensitivity level are canceled.

Note: When there are several marks of the same density level, data is also output in a plural

form.

Data of X+1 bytes a column x M1M2M3 columns

X + 1: 1-byte variable length data of number of marks + "CR"

N1N2N3 : 3-byte ASCII code indicating read start column number.

(Example) From the 3rd column = 003 (30H, 30H, 33H)

M1M2M3 : 3-byte ASCII code indicating number of columns to be read.

(Example) 50 columns = 050 (30H, 35H, 30H)

Note: N1N2N3 and M1M2M3 cannot be omitted as 6-byte fixed length data.

[Example]

When reading sensitivity = 3 and density difference = 4

Marks of reading sensitivity 3 or less are cancelled and the set density of 4 is subtracted from the

maximum density.

In this example, the density setting of 4 is subtracted from the maximum reading density of 10.

Accordingly, marks of reading density 6 (10 - 4 = 6) or less are cancelled.

This outputs data at mark positions 9 and 6.
