Ribbon error problem for Toshiba TEC B-SX4 Thermal Label Printer

SOURCE: Tec 572 printer gives "no ribbon" error with ribbon installed

You have to set the ribbon type to be "non-transmissive" for black transfer film.
To set the ribbon type, turn the printer off. Then press and hold the "feed" and "pause" buttons while turning on the power. The printer will now be in diagnostic mode - you can page through the menus until it says "ribbon type"
Pick the correct type and press the "pause" key to save the value. Then turn off the printer and turn it on again normally. The ribbon error goes away.

According to the user's manual this message indicates a problem with the ribbon sensor. As a test, set the unit for thermal direct printing and attempt to print a barcode. You will not see the code if yoiu are expecting thermal transfer, but the paper/label should feed like it is printing. That will indicate that the printer is functioning. At this point, the sensor needs to be replaced.

Hope this helps,

The printer default is ribbon trans.
if your ribbon is too dark you should modify this option to ribbon no trans
