VS-640 Damper (Original) - 1000012719
The Roland VS-640 Ink Damper (part number 1000012719, replacing discontinued 1000006526) is the genuine original Roland solvent-resistant ink damper for the Roland DX6 printhead pl atform — covering the VS, RE, RA, RF, XF, BN, EJ, RT, and XT series eco-solvent and dye-sublimation printers. Also cross-compatible with Mutoh printers using the PDAVJ161401O damper connector reference. This is the white/translucent damper recommended for use with all Roland Eco-Sol MAX (ESL) inks. The VS-640 and related DX6-based printers use 8 dampers per printhead — one per ink channel — and all 8 should be replaced simultaneously at every printhead installation. Every 1000012719 we stock at Digiprint USA is 100% genuine original Roland — not aftermarket, not compatible. White damper (1000012719) for Eco-Sol MAX inks — not the black damper (1000013784). Roland produces two DX6 damper variants. The white/translucent 1000012719 (this listing) is correct for all printers running Eco-Sol MAX inks — VS/RE/RA/RF/XF/BN/RT/EJ series. The black 1000013784 has a tighter mesh and is required for the LEC2-300 (UV ink) and XT-640 (sublimation ink) only. Using the wrong variant will cause either insufficient filtration or flow restriction.

The ink damper sits in the ink delivery path between the ink supply and the DX6 printhead — one damper per ink channel. It filters ink particles through its internal mesh screen, acts as a pressure buffer absorbing carriage acceleration shocks, and maintains stable negative back-pressure at the nozzle face. A worn damper — with ruptured membrane, cracked housing, or clogged mesh — causes ink starvation, air ingestion, or pressure instability that manifests as banding, colour channel drop-out, or nozzle row loss. Because the VS-640 uses 8 channels, partial damper replacement is a common mistake that leaves the root cause in place. OEM vs Compatible — Why Genuine Roland Matters for DX6 Dampers The Roland DX6 printhead in the VS-640 and related printers operates at precise negative-pressure tolerances tuned to the printhead's nozzle geometry and Eco-Sol MAX ink viscosity. The OEM Roland 1000012719 damper membrane is manufactured to exact compliance and spring-rate specifications that maintain the correct back-pressure across the full range of VS-640 carriage speeds and temperature conditions. Compatible/generic dampers may vary in membrane stiffness and internal geometry, potentially producing slightly different back-pressures that cause tonal inconsistency or intermittent nozzle starvation under high-speed production printing conditions. For VS-640 and RE-640 series printers running mission-critical production work, the genuine Roland OEM damper is the correct specification part. A compatible alternative is also available separately at lower cost. Signs Your VS-640 Dampers Need Replacing • Banding or nozzle row loss on specific colour channels — ink starvation from a restricted or failed damper • Air bubbles visible in the ink tube or damper body • Ink leaking from the damper housing — membrane rupture • Nozzle drop-out returning rapidly after cleaning cycles — air drawn through a compromised membrane • Discolouration or opacity change in the translucent damper body Roland VS-640 DX6 Maintenance Checklist • Ink dampers (this listing) — all 8 per head at every printhead installation • Head data cables — complete 4-piece set (3× 1000006702 + 1× 1000006703) for VS/RE/RA; 4× 1000006702 for XF-640 • Capping station — replace cap top at every head swap • Wiper blade — worn wipers deposit ink debris on the nozzle face Why Buy from Digiprint USA • 100% genuine original Roland 1000012719 — not aftermarket, not compatible • In stock in Doral, Miami FL — same day shipping before 2PM EST • Compatible version (1000012719-copy) also stocked at lower price for cost-managed maintenance • We also stock VS-640 head data cable sets, capping station, and wiper blade • Ideal for Latin American Roland VS/RE/RA service operations using Miami freight forwarders View our full range of Roland printer ink dampers and printer spare parts stocked by Digiprint USA. Frequently Asked Questions How many dampers does the Roland VS-640 require?The VS-640 uses 8 ink channels and requires 8 dampers — one per channel. All 8 must be replaced simultaneously at every printhead service. Replacing fewer leaves worn dampers causing starvation and air ingestion on the new head. For a dual-head printer, order 16 total. What is the difference between 1000012719 (white) and 1000013784 (black)?Both are genuine Roland DX6 dampers but with different internal mesh screens. The white 1000012719 uses a standard mesh for Eco-Sol MAX inks — correct for VS/RE/RA/RF/XF/BN/RT/EJ series. The black 1000013784 has a tighter mesh required only for UV inks (LEC2-300) and sublimation inks (XT-640). Always match damper colour to your printer model and ink type. What is the difference between this OEM listing and the compatible version?This listing is the genuine original Roland 1000012719 OEM damper — manufactured to Roland's exact membrane compliance and back-pressure specifications. We also stock a compatible/generic version of the same damper at a lower price point. For mission-critical production and warranty-sensitive applications, the OEM part is recommended. For routine maintenance in lower-intensity environments, the compatible version is a cost-effective alternative. Is 1000016472 the same as 1000012719?Yes — 1000016472 is a newer Roland OEM designation (IHP2 code) for the same white ESL damper. Some newer Roland service documentation references 1000016472. If your documentation shows this number, 1000012719 is the same part. Contact us if you need to confirm the current stock variant. Do you ship Roland VS-640 OEM dampers to Latin America?Yes — same day shipping from our Doral, Miami FL warehouse. Ideal for Latin American Roland service centres and VS/RE/RA eco-solvent operations using freight forwarders in the Doral area.
