The HP LaserJet Pro-550-sheet tray (manufacturer part number D9P29-67018) is a multi-purpose tray for HP LaserJet Pro series laser printers, specifically developed for businesses and business users. It serves as additional paper input to increase print capacity and enhance workflow efficiency. By integrating this tray, the overall paper capacity of the printer can be extended up to 900 sheets, reducing the need for frequent paper reloading. The tray is compatible with a wide range of HP LaserJet Pro models, including the M402d, M402n, M402dn, M402dw, M403n, M403d, M403dn, M403dw, M426dw, M426fdn, M426fdw, M427dw, M427fdn, and M427fdw series. The maximum paper capacity is 550 sheets, enabling uninterrupted processing of larger print jobs.

Applications
This input tray is designed for office environments requiring high print volumes and continuous availability of print materials. It is particularly suitable for individual users, small workgroups, and departments that frequently output large quantities of documents. Expanding the paper input reduces the need for frequent printer interaction, increasing productivity and streamlining workflows. Compatibility with various models in the HP LaserJet Pro series makes it a universally applicable accessory.

Features and Equipment in Detail
The tray allows loading of two different paper types, increasing flexibility in printing operations. Supported media types include various paper grades such as plain, EcoFFICIENT, light, heavy, bond, coloured, letterhead, preprinted, prepunched, as well as recycled and textured paper. Additionally, envelopes, labels, and film can be processed. Supported media sizes range from A4 to A6 and B5 (JIS). The maximum paper capacity of 550 sheets allows loading entire paper bundles, extending print time without interruption. The tray dimensions are 381 mm (width) × 357 mm (depth) × 131 mm (height), with a weight of 3.7 kg.

Technology Explained Simply
The input tray is a mechanical add-on module attached to the printer to extend paper input. It features a robust construction designed for office environments. Paper feeding is handled by a mechanical transport mechanism that feeds paper evenly and reliably into the printer. Compatibility with various printer models is ensured through standardized connection points and mechanical fit. Operating conditions include a relative humidity of 10 to 80 %, enabling use in typical office environments.

Compatibility and Accessories
The tray is specifically designed for HP LaserJet Pro models M402d, M402n, M402dn, M402dw, M403n, M403d, M403dn, M403dw, M426dw, M426fdn, M426fdw, M427dw, M427fdn, and M427fdw. Compatibility is confirmed by manufacturer specifications. No additional accessories are required for installation. Installation is performed by mechanical attachment to the printer, requiring no additional tools or settings.

Installation and Mounting
Mounting the input tray involves simply attaching it to the printer, where mechanical latches and connection points ensure correct positioning. No tools are required, and installation can be performed by a user without technical expertise. Installation instructions are included in the manufacturer’s documentation, available on the HP website.

Operational Advantages
Extending the paper input to 550 sheets prolongs uninterrupted print time, increasing productivity. The ability to supply two different paper types simultaneously reduces the need to stop the printer for media changes. Reduced user interaction leads to more efficient printer usage and allows focus on other tasks. The tray is designed for use in business and enterprise environments, with a 1-year warranty. The product is manufactured in the Philippines and designed for use in office environments with normal humidity levels.
