Roland eco-solvent printers use one of three Epson printhead families — the DX4, DX5, or DX6/DX7. Which one is in your machine depends on the model and the year it was manufactured. Get the wrong one and you have an expensive problem, because printheads are final sale once opened.
This guide covers exactly which head your Roland takes, the correct part number, what the head typically fails from in Roland service, and what to order alongside it.
A note on DX6 vs DX7 in Roland service
Roland technicians and parts suppliers use these terms interchangeably, and for good reason. The DX6 and DX7 are closely related Epson piezo heads with overlapping Roland applications. Most Roland-compatible inventory is cross-referenced under both names. Throughout this guide we use "DX7" as the umbrella term — if your tech told you the printer takes a DX6, the same Roland-badged part covers it.

Important caveat: Roland made running production changes, particularly during the DX5-to-DX7 transition window between 2008 and 2012. If your printer is from that period, confirm against the serial number before you order. Email us at info@digiprint-usa.com with your model and serial number and we'll confirm the right part before anything ships.
The DX4 — early Roland series (1998 to ~2008)
Part number: 6000005213. First-generation industrial Epson piezo head. Used in Roland SC, SJ, FJ, and SP-series machines. Eco-solvent only — no UV or water-based variant for these Roland applications. If your printer predates 2008, this is almost certainly the head it uses.
The DX4 is still in production at Epson Japan, which surprises some Roland owners who assume parts support has ended for older machines. The head design is straightforward and the supply chain is stable. Digiprint stocks genuine Epson DX4 (6000005213) at $575, shipping same day from Florida.
What kills DX4 heads in Roland service: the dampers fail first, typically around 18 to 24 months in daily eco-solvent production. Then the wiper blade. The head itself can outlive both parts if you stay ahead of those consumables. Most DX4 failures we see trace back to a worn capping station or degraded dampers, not the head. For the full picture on how these peripheral parts interact with printhead longevity, see our guide on dampers, capping stations, and wiper blades.
The DX5 — Roland XC-540 and transitional builds (~2007 to 2012)
Part number: F186000 and variants. Mid-generation head used in the Roland XC-540 (a four-head CMYKLcLm wide-gamut solvent machine) and some transitional VS-series builds. Less common in Roland service than the DX4 or DX7, but well represented in shops that bought XC-540s in the 2007 to 2012 window.
The DX5 comes in several variants — solvent, water-based, and dye-sublimation — that are physically identical from the outside. The wrong variant fails within hours of ink contact, because the internal coatings are application-specific. When sourcing a DX5 replacement, the variant matters more than the model number. Tell us what ink type you're running and we'll confirm the correct variant before shipping.
What kills DX5 heads in Roland service: variant mismatch is the most common cause of early failure. After that, the same damper and capping station issues that affect DX4 machines — the peripheral parts are the same failure pattern across all Epson DX-family heads. Check the dampers and capping station first if you're seeing print quality degradation.
The DX7 (Roland-badged DX6/DX7) — current Roland series (2010 to present)
Part number: F189010 and variants, Roland part number 6701409010. This is the head in all current Roland VS, XR, XF, VG, VG2, VG3, and BN-series printers. Higher resolution, faster firing frequency, and longer service life than DX4 or DX5 in equivalent use conditions.
The Roland-badged DX6/DX7 is what most current Roland owners are searching for when they type "Roland printhead replacement" — whether they call it DX6 or DX7. It's also the head most affected by white ink on Roland machines configured with white channels, since white ink's high pigment load accelerates damper wear.
What kills DX7 heads in Roland service: capping station wear is the leading cause. Roland's capping station designs on the VS and VG series are well-engineered, but they need replacement every 12 to 18 months in daily production. A worn cap means the head dries out overnight, and you spend ink cycling through cleaning attempts trying to recover nozzles that are mechanically blocked. The second leading cause is running with low ink — the DX7 does not tolerate air pulled into the head from an empty cartridge. If your Roland has run dry mid-job, inspect the dampers and run a thorough nozzle recovery sequence before assuming the head is gone.
Where Roland printheads actually come from
Roland does not manufacture printheads. They purchase Epson piezo heads and apply Roland part numbers and Roland firmware configurations. The physical head inside a Roland-labeled box is the same DX4, DX5, or DX7 family head that Epson makes for industrial customers.
What Digiprint sells for current Roland VS, XR, XF, VG, and BN-series machines is the Roland-badged DX6/DX7 — Roland's own labeling and part numbering, which is what Roland service techs and Roland firmware are set up to recognize without modification. We don't substitute unbadged industrial Epson DX7 units as Roland replacements. Some shops make that work, but the Roland-badged path is cleaner on installation and eliminates the firmware conversations that otherwise come up.
Roland-specific failure patterns that aren't the head
Old cleaning solution that has gone acidic. Roland eco-solvent ink and its matching cleaning solution have a shelf life. Past 18 months, cleaning solution can become aggressive enough to attack the nozzle plate during routine maintenance. If you've been sourcing cleaning solution from inconsistent suppliers, check the manufacture date. This is a more common cause of nozzle plate damage in Roland service than most owners expect. For how to identify genuine nozzle plate damage vs a recoverable clog, see our guide on how to tell if your printhead needs replacing.
Power cycling during cleaning operations. Roland firmware does not gracefully recover from interrupted cleaning cycles. If you cut power using a wall switch while a cleaning cycle is running, the head parks in a non-standard position and the next startup can introduce air into the ink path. Always use the printer's power button and let the shutdown sequence complete.
Running with low or empty ink. The DX4 and DX7 in particular do not tolerate air drawn into the head from an emptied cartridge. If a Roland runs out of ink mid-job and air gets pulled through, you can lose the head even after refilling. Set your low-ink warning threshold higher than the default and stop printing when it triggers.
All three of these failure causes are preventable without buying a single part. For a broader view of the recurring patterns that cause premature head failure across all wide format platforms, see our OEM vs generic printer parts guide — the Roland-specific insight there is how cleaning solution quality affects nozzle plate life over time.
What to order and how to confirm the right part
Genuine Epson DX4 (part 6000005213) at $575. In stock, shipping same day from Miami. For Roland SC, SJ, FJ, SP-series machines. Order the DX4 here.
Roland-badged DX6/DX7 for VS, RA, RE, XR, XF, VG, VG2, VG3, and BN-series printers. Email info@digiprint-usa.com with your Roland model and serial number — the DX7 has multiple sub-versions and the model plus serial is how we confirm which variant you need before it ships. View the Roland VS series DX6/DX7 listing here.
Genuine Epson DX5 (multiple variants) for Roland XC-540 and transitional builds. Email info@digiprint-usa.com with your printer model and ink type. Both are needed to confirm the correct variant.
Roland-compatible dampers and capping stations for DX4, DX5, and DX7 platforms. Replace these at the same time as the head — the head failed for a reason, and the most common reason is worn peripheral parts. Installing a new head on old dampers and a cracked capping station repeats the failure within months. Browse our full printheads catalog and Epson printhead range for everything in stock.
If you're not sure which head is in your Roland, email info@digiprint-usa.com with the printer model and serial number before you order. Printheads are final sale — getting the right part confirmed before checkout is the most important step in the process. We would rather spend five minutes on an email than have you receive the wrong part.
