TM-U675 Printer FAQ

It's possible that the paper is not correctly inserted; check this and try again. If this still fails to turn off the PAPER OUT light, its likely a defective/dirty paper sensor.

This indicates an error condition in the Epson circuitry. Turn off the printer, make sure there is not a paper jam, and retry. If the RELEASE light still flashes it indicates a short or a open circuit that shouldn't be.

This is likely due to a cable issue (try disconnecting everything, then reconnecting) or a software configuration issue.

The TM-U675 generally needs the COM or parallel port open in Windows—if any other devices are using this port (other printers, devices etc), uninstall them. In Window XP check this by going to Control Panel > System > Hardware > Device Manager > Ports.

The most common source of problems for installation is incorrect software configuration. Most software that is written to use the TM-U675 directly interacts with the printer via RS-232 (serial) or parallel, thus a driver is not needed. You may need to check with the vendor of your particular software for support. Information on the Epson Windows driver utility is available here.

If all else fails, try to use the Epson windows driver above. If you still can't establish any communication, you may have hardware problem. If you can establish communication, but your software won't print to the TM-U675, call the software vendor; this indicates a configuration issue.

The paper must be release (press the RELEASE button), make sure the ribbon is wound up all the way (turn the ribbon wheel to tighten the ribbon) and try again. This can be a little tricky.

Generally all switches should be in the "off" position. The DIP switches control baud rate (transmission rate), parity, and other functions. For a list of what each switch does, please see our TM-U675 support page
