G-011 RP-A3 Pressure Roller for Riso GR 3750 GR3790

To ensure consistent print quality and reliable feeding through your Riso, use a high-quality G-011 RP-A3 Pressure Roller. This part is essential to the Print Drum Assembly and works in conjunction with the Impression Cylinder, providing the proper pressure for transferring ink from the master onto the paper.

The Pressure Roller may become worn, flat, or glazed after extensive use, resulting in printing problems (faint prints, ink streaks, and/or feeding difficulties). To restore the printing functionality of your Riso GR series to its original state and prolong the life of your duplicator, replace the Roller with this durable replacement part.
