Product Review: Roland XC-540/XJ-640/XJ-740 Head Board for 6 Heads (6700731100) I recently purchased the Roland XC-540/XJ-640/XJ-740 Head Board for 6 Heads and I must say, it exceeded my expectations. The head board is well constructed and feels very sturdy. It's also easy to install and set up, which was a nice surprise given the complexity of some other products in this category. One thing that stands out about this product is its versatility. It can be used with a variety of Roland printers including XC-540/XJ-640/XJ-740, which makes it a great investment for anyone looking to upgrade their printer setup. The head board also features six heads, which allows for more efficient printing and faster turnaround times. Another thing I appreciate about this product is its compatibility with different types of inks. It can be used with both solvent-based and eco-solvent inks, which gives users the flexibility to choose the type of ink that best suits their needs. This also means that it's a great option for those who want to switch between different types of inks without having to purchase new hardware. Overall, I would highly recommend this product to anyone looking for a reliable and versatile head board for their Roland printer setup.
