Upgrade a 2155cn to 2155cdn

Unfortunately, simply upgrading the Duplex Feed Assembly may not be enough to turn your Dell 2155cn into a 2155cdn model. The Dell 2155cn and 2155cdn printers have different hardware components and firmware, so upgrading a single part will not necessarily make the printer function like the other model.

To upgrade your Dell 2155cn to a 2155cdn model, you would need to replace the entire printer with the 2155cdn model, or at least replace the major hardware components such as the engine controller board, power supply, and duplex unit. This would require technical expertise and specialized tools.

It's important to note that modifying your printer in this way may also void your warranty or cause other issues, so it's important to weigh the benefits against the potential risks before attempting any modifications.
