Hi. I'm Bill Brown from B&B Supply, PriceGunStore.com, and I'm going to show you how to change an ink roller in a Towa GL Samurai 2-Line Price Gun. Click the hand trigger, and lift up on the ink roller assembly. With your thumb and index finger, take either side of the ink roller, and remove it from its holders. To place a new ink roller on, simply repeat the process, securing it into the holders, then lightly press the ink roller assembly back down. The Towa 2-Line GL Samurai now has a new ink roller.
