Sumitomo CNVMS-4085G-43/G Ink Fountain Motor
Overview
The Sumitomo CNVMS-4085G-43 Ink Fountain Motor is a precision motor designed for compatible offset printing presses. It is identified by the CNVMS-4085G-43/G model reference and the L2.105.1051/01 part number. The motor is used in the ink fountain system to adjust ink flow across the printing plate. Accurate ink control is essential for consistent color and print quality. The motor responds to commands from the printing press control system. It is built for reliable operation in the demanding environment of a printing shop. The CNVMS-4085G-43 is a key component in the ink delivery system.
Ink Fountain Function
The ink fountain holds ink and delivers it to the rollers. The fountain blade or roller position determines how much ink is released. The CNVMS-4085G-43 motor adjusts this position with precision. It may drive a segment of the fountain or the entire blade depending on the press design. The motor receives signals from the press controller to open or close the ink gap. This allows the operator to set ink profiles for different jobs. Fine adjustment helps maintain color density across the sheet. If the motor fails, ink control may be uneven or unresponsive. Proper calibration is important for accurate ink delivery.
Motor Design and Performance
The Sumitomo CNVMS-4085G-43 is a compact motor designed for precise positioning. It provides smooth rotation and reliable torque for ink fountain adjustment. The motor is built with durable components that resist wear and heat. It operates quietly and with low vibration. The electrical connections are designed for stable signal and power transfer. The motor may include feedback devices to confirm position. This feedback helps the controller maintain accurate ink settings. The motor is compatible with the CD74 and XL75 offset press families. Proper installation and alignment help ensure reliable performance.
Compatibility and Installation
Technicians should confirm that the motor matches the compatible press model and ink fountain design. The CNVMS-4085G-43/G and L2.105.1051/01 references help identify the correct unit. The press should be powered down and locked out before service. The motor should be mounted securely and connected to the correct drive circuit. Wiring should follow the press manufacturer recommendations. After installation, the motor should be calibrated so that ink settings match the control system. Test prints should be checked for color consistency. Following approved procedures helps ensure reliable operation and print quality.
