Mutoh VJ-1638 CR Board Assy - DG-43321

The Mutoh VJ-1638 CR Board Assembly DG-43321 is the carriage board for the Mutoh Valuejet 1638 series. The CR (carriage) board sits on the print carriage and manages communication between the main board and the printhead, controlling ink firing signals and carriage position data. A faulty CR board typically causes printhead errors, banding, or complete loss of print output.
