Interface Troubleshooting - SATO LC400e Series Operator's Manual

5.3 INTERFACE TROUBLESHOOTING

This chapter provides a checklist for the various interface types. Locate the checklist relative to the interface
used and perform each of the troubleshooting tasks until the problem has been isolated.
IEEE1284 PARALLEL INTERFACE
CHK
Make sure the interface module is correctly installed. Run self-test to verify.
Make sure the printer cable is connected to the appropriate LPT port on the host computer. If using a Windows
printer driver, make sure the correct port is selected.
Make sure an IEEE1284 printer cable is being used.
Make sure the host's peripheral settings are set to ECP for faster throughput. Refer to the computer
manufacturer's documentation for details.
Make sure the printer is receiving information from the computer using the Receive Buffer Hex Dump mode.
Refer to that procedure within this manual for instructions. The command stream should be continuous and
possess 0Dhex (carriage return) or 0Ahex (line feed) or both characters throughout. However, there should not
be either located between the start (<ESC>A) and the stop (<ESC>Z) commands.
Try another port to isolate the problem.
Replace the main circuit board if determined to be the problem.
RS-232C SERIAL INTERFACE
CHK
Make sure the correct interface module is correctly installed. Run self-test to verify.
Make sure the serial cable (Null Modem) meets specifications and is correctly connected at each end.
Make sure the serial cable is not defective.
Make sure the communication parameters for the baud rate, parity, data bits and stop bits are consistent with
those being sent from the host computer.
Make sure the printer is receiving information from the computer using the Receive Buffer Hex Dump mode.
Refer to that procedure within this manual for instructions. The command stream should be continuous and
possess 0Dhex (carriage return) or 0Ahex (line feed) or both characters throughout. However, there should not
be either located between the start (<ESC>A) and the stop (<ESC>Z) commands.
Try another port to isolate the problem.
Replace the main circuit board if determined to be the problem.
UNIVERSAL SERIAL BUS (USB) INTERFACE
If nothing prints during a test print, verify the device drivers have been successively installed by performing the following:
CHK
Click on Start, Settings, and then Control Panel.
Click on System within the new window.
Click on the Device Manager tab.
Make sure that the View Device By Type is checked.
Scroll to SATO-USB Device and make sure that errors do not exist. Reinstall as required.
Reboot the PC and the printer.
