2.3.2 Scanning Method
Ordinary Read
This function reads one bar code at a time and outputs the data. Ordinary, this read method is
used.
Multi-step Read
This function continuously performs decoding as long as one of the R/L Trigger keys is held down.
Once bar codes are decoded they are not read any more. This function is useful for reading all bar
codes without repeating the same action when more than one bar code is printed on one slip.
Package Read
This function outputs the read result retrieved from more than one bar code in a package. With the
multi-step read function, once bar codes are decoded they are not read any more. This is useful for
handling multiple pieces of bar code data. However, if any of the following unfavorable
conditions occur, all the bar codes may not be read in one capture:
- The objective bar code of read is not contained in the captured image.
- The focus is not sharp enough.
- The exposure is not correct.
Table 2.57 Difference between Multi-step and Package Reads
Performance Multi-step Read Mode Package Read Mode
Maxi. no. of bar codes to
read
(Max. no. of read steps) 10 10
Max. no. of digits to read 4,095 4,095 (see note below.)
Total no. of digits to read 4,095 x 10 = 40,950 4,095
Read method Continuously reads the specified
number of bar codes as long as
the Program key is held down.
Different from Package read in
which multiple bar codes are read
at a single scan, a single kind of a
symbol will be continuously read
through multi read steps. If one
bar code is read, the buzzer
sounds and the LED turns on. Multiple bar codes are read in a
single scan.
Neither the buzzer sounds nor the
LED turns on until the specified no.
of bar codes has been read.
Recommended method
of use This mode is suitable in the
following cases:
If the bar code has many digits.
If the target bar codes are spaced.
To positively confirm a read. This mode is suitable in the following
case:
If multiple bar codes with small
number of digits are adjacent to one
another.
Note:
The terminal is designed so that a maximum of 10 bar codes or 4,095 digits of bar codes can be
read. However, it is not recommended for the user to use the package read mode for reading bar
codes consisting of a large number of digits. If the number of bar codes is greater than 4, or if the
total number of digits is greater than 100, use the multiple-step read mode as much as possible.
