The Epson DX7 is a seventh-generation MicroPiezo printhead and one of the most capable solvent heads ever built. The 1st coded version is the specific variant required for Roland printers. Every DX7 we sell at Digiprint USA is 100% genuine original Epson. Please Note: Due to the delicate nature of DTF inks and the risk of damage from improper installation or nozzle blockage, we cannot accept returns, exchanges, or refunds once the printhead has been installed. All sales are final. Please ensure proper installation procedures are followed.

This is the most important question when ordering a DX7. The coding refers to the firmware chip on the printhead that communicates with your printer's control board. Roland printers require the 1st coded version. Chinese eco-solvent printers typically require the 2nd coded (unlocked) version. Installing the wrong coded version will result in the printer not recognising the head. Contact our team before ordering — we confirm compatibility for every customer at no charge. Compatible Printers — 1st Coded The 1st coded DX7 is specifically engineered for Roland eco-solvent printers. For Chinese-manufactured eco-solvent printers using the DX7 platform, you need the 2nd coded (unlocked) version — see our separate listing. Recommended Accessories — Replace at the Same Time When replacing a DX7 on a Roland RE-640, VS-640, or RA-640 always replace the head data cables at the same time. Installing a new head on worn cables is the most common cause of premature DX7 failure and is not covered under warranty. In eco-solvent use a DX7 printhead typically lasts 9 to 12 months — see our printhead lifespan guide for replacement cycles by model and tips to extend service life. • Roland DX7 head data cable set — 4-piece set, 28-pin and 29-pin cables for RE-640, VS-640, RA-640 • Eco-solvent dampers — replace when fitting a new head Contact our team before ordering to confirm the correct cable set for your exact Roland model.

Frequently Asked Questions What is the difference between DX7 1st coded and 2nd coded?The 1st coded version communicates with Roland printer control boards. The 2nd coded (unlocked) version is for Chinese eco-solvent printers using the DX7 platform. Installing the wrong version means the printer will not recognise the printhead. If you are unsure, contact our team with your printer model and we will confirm the correct version at no charge. Which Roland printers use the DX7 1st coded?RE-640, RE-640G, VS-640, VS-640i, RA-640, RF-640, RF-640A, XF-640, XR-640, BN-20 (some variants), and EJ-640. If your Roland model is not on this list contact our team before ordering. What cables do I need when replacing a Roland DX7?Roland RE-640, VS-640, and RA-640 use a 4-piece head data cable set — two 28-pin and two 29-pin cables. The part numbers are Roland 1000006702 and 1000006703. We stock these — add them to your order before checkout via our cables section. How long does the DX7 printhead last?In typical eco-solvent use the DX7 lasts 9 to 12 months — much longer than DTF printheads, because eco-solvent inks are far less abrasive on the nozzle plate than water-based DTF white ink. Replacing the head data cables at each head change is the single most important step to avoid premature failure. See our printhead lifespan guide for full data across all Epson models. What is the difference between DX7 and DX6?The DX6 has 360 dpi native resolution. The DX7 has 1440 dpi native resolution with more refined dot placement. They are not interchangeable. Check your Roland model against the compatibility lists above before ordering. Do you ship to Latin America?Yes — same day shipping from our Doral, Miami FL warehouse.
