3.8.1 Q: Why has my print data dropped out?
A: Check the handshake process. Data dropout can occur when the handshake between the
host computer and printer is not performed correctly. This can result in errors related to
print buffer size.
3.8.1.1 Corrective procedure
1. Check the serial communication cable, and check the cable connector specifications.
(See “Serial Interface Connection” on page 2-8.)
2. Check the serial communication conditions of the printer and the host.

•Parity
•Flow control
•Data length
You can check printer settings as follows:
1. Run a self-test to check the printer’s serial communication conditions. (See page 3-13.)
2. Setting communication conditions using the DIP switches. Set the baud rate with DIP
SW1-7 and SW1-8. (Refer to page 2-4.)
