Toshiba 6LB61737000 | BV410T/BV420T Ribbon Spindle Adapter - ASYB-SPOOL-RBN-BVT-FRU

The Toshiba 6LB61737000 | BV410T/BV420T Ribbon Spindle Adapter (ASYB-SPOOL-RBN-BVT-FRU) is the genuine OEM replacement spindle that secures your thermal transfer ribbon roll inside Toshiba BV410T and BV420T desktop printers. Designed to maintain correct ribbon alignment and even tension across the print path, this field-replaceable unit helps prevent ribbon wrinkling, edge fade, and misfeeds—protecting printhead life while ensuring sharp barcodes and solid black graphics on both paper and synthetic labels.

Ideal for restoring performance after wear, damage, or frequent media changes, this FRU installs quickly and seats the ribbon core precisely for consistent, professional results. Compatible with Toshiba BV410T and BV420T printers, it’s the reliable way to keep your operation running smoothly with minimal downtime.

What’s included: The Toshiba 6LB61737000 | BV410T/BV420T Ribbon Spindle Adapter package contains one ½-inch core ribbon spindle adapter for Toshiba BV410T/BV420T printers, plus a 1-inch core adapter that nests on top. Use the ½-inch spindle adapter by itself to install our 74-meter ribbons with ½-inch cores. If you want to run larger 300-meter ribbons (which have 1-inch cores), simply attach the 1-inch core adapter on top of the ½-inch spindle adapter—this stacked setup securely holds the larger 300-meter rolls.

Tip: If you’ve misplaced the adapter set that ships with new printers, consider purchasing two kits—one for the supply (new ribbon) side and one for the take-up rewinder side, where the used ribbon is rewound during printing.
