The 50GA-53040 Lower Pressure Roller is designed for Bizhub 420 and 421 copier models from Konica Minolta. As an essential component inside the fuser assembly, this lower pressure roller ensures stable and uniform pressure during the toner fixing process, directly affecting print clarity and paper output quality.
Bizhub 420 and 421 are high-speed monochrome copiers widely used in offices, copy centers, and production environments. Due to their heavy-duty workload, the fuser unit operates under continuous high temperature and mechanical pressure. A durable and precisely manufactured lower pressure roller is critical for maintaining consistent performance and reducing machine downtime.
A high-quality compatible roller helps prevent common fusing problems such as:
• Toner offset
• Uneven fixing
• Ghosting
• Paper wrinkles
• Frequent paper jams
TOC is a professional manufacturer specializing in compatible copier spare parts for global B2B markets. Our 50GA-53040 lower pressure roller is engineered with strict dimensional tolerance to ensure seamless compatibility with Bizhub 420 421 devices. The rubber compound is formulated for strong heat resistance and balanced elasticity, providing consistent pressure distribution during long print runs.
Product features include:
• Heat-resistant rubber material for stable fixing performance
