An online inkjet printer with a conveyor is an industrial machine that automatically prints variable information, such as batch codes, expiration dates, and barcodes, onto products as they move along a conveyor belt. This all-in-one system is designed for high-speed production lines and is used to efficiently apply clear, high-resolution text, logos, and other codes onto a variety of surfaces like cardboard, plastic, metal, and glass. 

Key components and features

• Inkjet Printer: Uses thermal inkjet (TIJ) technology to produce sharp, high-resolution prints (often up to 600 DPI). It can be a compact unit mounted above or next to the conveyor.
• Conveyor Belt: A powered belt system that moves products smoothly under the printer for consistent and accurate print application.
• Printing Surface: Capable of printing on a wide range of materials including paper, cartons, plastic, metal, glass, and even some curved surfaces.
• Printing Contents: Can print essential information such as:
  • Production and expiration dates
  • Batch and lot codes
  • Barcodes and QR codes
  • Logos and serial numbers
• Adjustable Stand: Many systems include an adjustable stand to easily change the height and angle of the printer to accommodate different product sizes.
• User Interface: Often controlled via a simple screen, such as a 5-inch touch screen, and can be integrated with other software systems.
• Speed: Designed for high-volume applications, with many systems capable of high-speed operation (e.g., 60 pieces per minute or more).
• Technology: Relies on proven technologies like HP 45 inkjet cartridge technology and fast-drying solvent inks suitable for various surfaces. 

How it works

1. Loading: Products are placed on the conveyor belt, either manually or automatically, and are aligned to move smoothly under the printer.
2. Sensing: A sensor detects the product's presence and position as it passes the print head.
3. Printing: The inkjet print head sprays the required information (dates, codes, logos) onto the surface of the product as it travels along the belt.
4. Output: The printed product continues along the conveyor to the next stage of the production process, such as packaging or sorting.
