Restore smooth printhead positioning, clean electrical signal transmission, and leak-free ink tube routing with this Original Refurbished Printhead Carriage Unit for Canon Pixma G-Series printers. In Canon G-series ink-tank printer architectures, the carriage unit is the central electro-mechanical component that travels back and forth across the page during printing. It anchors the Black (B) and Color (C) cartridge-style printheads while securing the continuous ink supply tubes via a top-locking latch.
Mechanical & Electrical Failure Modes:
Through long-term high-volume printing, ink leaks, or harsh maintenance handling:
- Contact Pin Corrosion / Shorting: Ink leakage or mist coats the gold electrical contact pins inside the printhead slots, causing intermittent electronic disconnects or burning out printhead communication lines.
- Carriage Latch Flex / Hinge Failure: The top blue locking clamps break, crack, or lose latching pressure, resulting in air entering the ink tubes or loose printhead seating.
- Rear Encoder Sensor Failure: The optical encoder sensor mounted on the back of the carriage becomes contaminated with ink mist, preventing position detection on the linear scale.
- Bush / Slider Wear: The plastic guide bushings that slide along the steel rail wear out or lose lubrication, leading to carriage drag, misalignment, or mechanical strain.
Key Symptoms Solved:
- Printhead Unrecognized Error (Support Code 1401 / 1403 / 1430): The printer fails to detect inserted printheads due to bent, broken, or corroded electrical contact pins inside the carriage slots.
- Carriage Jam / Grinding Noise (Support Code 5100): The carriage stutters, locks up, or slams during movements due to damaged rear slider bushings or obstructed sensor paths.
- Color Dropping / Air Bubble Intrusion: Worn or damaged tube connection joints on top of the carriage allow air into the ink lines, causing continuous ink starvation.
Reconditioned from genuine OEM core units, this refurbished carriage assembly is fully tested to ensure proper contact pin alignment, latch lock tension, and smooth rail travel.
