Epson DLQ-3500ii carriage assembly (1824254)

The Epson DLQ-3500II Carriage Assembly (Part No. 1824254) is a genuine OEM replacement unit designed to drive the printhead across the platen with precision, stability, and high-speed motion. As one of the most critical mechanical components in the DLQ-3500II dot-matrix printer, the carriage assembly ensures accurate lateral movement, synchronized ribbon alignment, and proper head positioning for crisp, consistent print output.

This assembly integrates multiple precision-engineered components including the carriage frame, printhead mounting slot, guide roller bushings, belt attachment mechanisms, movement rail sliders, and head-drive linkages. Each element is built to Epson’s high durability standards to withstand heavy-duty enterprise printing environments such as banks, logistics offices, government departments, and industrial billing setups.

Working in coordination with the drive motor, encoder strip, ribbon drive system, and main board, the carriage assembly ensures smooth motion even during continuous multi-copy form printing. Its reinforced structure minimizes vibration, reduces friction, and maintains stable head pressure for accurate character alignment and long printhead life.

Common signs of a faulty carriage assembly:

• No or jerky printhead movement

• Grinding or friction noise during carriage travel

• Misaligned prints or uneven text spacing

• Paper jam errors due to head misalignment

• Frequent printhead strikes or ribbon feed irregularities

• Carriage motor overload or position errors
