The damper regulates ink back-pressure between the ink supply and the GH2220 printhead, buffers pressure fluctuations caused by carriage movement, and filters particles from the ink before they reach the nozzle channels. Compatible with UV-curable, solvent, and aqueous ink systems on Oric, WER, Winjet, Yuxunda, Xante, Ricoh DTG, Colorjet, and Gunsjet GH2220-based printers. Replace the damper at every GH2220 printhead installation and on a scheduled maintenance interval.\u003c\/p\u003e\n\u003ch3 style=\"margin-top: 20px; margin-bottom: 10px; font-size: 14px;\"\u003e\u003cstrong\u003eProduct Details\u003c\/strong\u003e\u003c\/h3\u003e\n\u003ctable style=\"width: 100%; border-collapse: collapse; margin-bottom: 15px; font-size: 13px;\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"background: #f9f9f9;\"\u003e\n\u003cth style=\"border: 1px solid #ddd; padding: 7px 10px; text-align: left; font-weight: 600;\"\u003eSpecification\u003c\/th\u003e\n\u003cth style=\"border: 1px solid #ddd; padding: 7px 10px; text-align: left; font-weight: 600;\"\u003eDetail\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border: 1px solid #ddd; padding: 7px 10px;\"\u003eCompatible printhead\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #ddd; padding: 7px 10px;\"\u003eRicoh GH2220\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border: 1px solid #ddd; padding: 7px 10px;\"\u003eInk compatibility\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #ddd; padding: 7px 10px;\"\u003eUV-curable, solvent, and aqueous inks\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border: 1px solid #ddd; padding: 7px 10px;\"\u003eFunction\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #ddd; padding: 7px 10px;\"\u003eInk back-pressure regulation, pressure stabilisation, particle filtration\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border: 1px solid #ddd; padding: 7px 10px;\"\u003eReplacement interval\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #ddd; padding: 7px 10px;\"\u003eReplace at every printhead installation; replace every few months in production use\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch3 style=\"margin-top: 20px; margin-bottom: 10px; font-size: 14px;\"\u003e\u003cstrong\u003eWhat Does the GH2220 Damper Do?\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp style=\"margin-bottom: 12px;\"\u003eThe GH2220 printhead requires a precisely controlled negative back-pressure at its ink inlet to maintain stable ink menisci at each nozzle opening. Without correct back-pressure — maintained by the damper's internal membrane — ink floods through the nozzles at rest (positive pressure) or air is drawn into the nozzle channels (excessive negative pressure). Both conditions cause print quality failure. The damper also absorbs the rapid pressure fluctuations caused by carriage acceleration and deceleration during printing, preventing those spikes from reaching the printhead and causing droplet size variation and banding. A secondary function is particle filtration — the damper's internal screen traps particles before they can reach and score the GH2220's precision silicon nozzle plate.\u003c\/p\u003e\n\u003ch3 style=\"margin-top: 20px; margin-bottom: 10px; font-size: 14px;\"\u003e\u003cstrong\u003eSigns the GH2220 Damper Needs Replacing\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp style=\"margin-bottom: 4px;\"\u003e• Banding or streaking that persists despite cleaning cycles — pressure instability from a failed damper membrane\u003c\/p\u003e\n\u003cp style=\"margin-bottom: 4px;\"\u003e• Ink leaking from the damper body — seal failure\u003c\/p\u003e\n\u003cp style=\"margin-bottom: 4px;\"\u003e• Air bubbles in the ink supply line after the damper — membrane permeability failure\u003c\/p\u003e\n\u003cp style=\"margin-bottom: 4px;\"\u003e• Inconsistent drop formation — damper no longer buffering carriage pressure spikes\u003c\/p\u003e\n\u003cp style=\"margin-bottom: 12px;\"\u003e• Scheduled replacement — every few months in production use, or at every printhead installation\u003c\/p\u003e\n\u003ch3 style=\"margin-top: 20px; margin-bottom: 10px; font-size: 14px;\"\u003e\u003cstrong\u003eCompatible Printers\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp style=\"margin-bottom: 10px;\"\u003eThis damper is compatible with all printers using the Ricoh GH2220 printhead, including:\u003c\/p\u003e\n\u003cdiv style=\"display: grid; grid-template-columns: 1fr 1fr 1fr; font-size: 13px; gap: 2px 0;\"\u003e\n\u003cdiv style=\"color: #d36b03; padding: 2px 0;\"\u003e\u003cstrong\u003eColorjet Verve Mini\u003c\/strong\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv style=\"grid-column: 1\/-1; height: 8px;\"\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv style=\"color: #d36b03; padding: 2px 0;\"\u003e\u003cstrong\u003eGunsjet GSJ-GH-UVF1016V\u003c\/strong\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv style=\"grid-column: 1\/-1; height: 8px;\"\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv style=\"color: #d36b03; padding: 2px 0;\"\u003e\u003cstrong\u003eOric TS1519-GH-6H\u003c\/strong\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv style=\"grid-column: 1\/-1; height: 8px;\"\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv style=\"color: #d36b03; padding: 2px 0;\"\u003e\u003cstrong\u003eRicoh DTG Ri1000x\u003c\/strong\u003e\u003c\/div\u003e\n\u003cdiv style=\"color: #d36b03; padding: 2px 0;\"\u003e\u003cstrong\u003eRicoh DTG Ri2000\u003c\/strong\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv style=\"grid-column: 1\/-1; height: 8px;\"\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv style=\"color: #d36b03; padding: 2px 0;\"\u003e\u003cstrong\u003eWER R1808\u003c\/strong\u003e\u003c\/div\u003e\n\u003cdiv style=\"color: #d36b03; padding: 2px 0;\"\u003e\u003cstrong\u003eWER R3208\u003c\/strong\u003e\u003c\/div\u003e\n\u003cdiv style=\"color: #d36b03; padding: 2px 0;\"\u003e\u003cstrong\u003eWER R3T\u003c\/strong\u003e\u003c\/div\u003e\n\u003cdiv style=\"color: #d36b03; padding: 2px 0;\"\u003e\u003cstrong\u003eWER RD3T\u003c\/strong\u003e\u003c\/div\u003e\n\u003cdiv style=\"color: #d36b03; padding: 2px 0;\"\u003e\u003cstrong\u003eWER RF1808\u003c\/strong\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv style=\"grid-column: 1\/-1; height: 8px;\"\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv style=\"color: #d36b03; padding: 2px 0;\"\u003e\u003cstrong\u003eWinjet W2-GH2220\u003c\/strong\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv style=\"grid-column: 1\/-1; height: 8px;\"\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv style=\"color: #d36b03; padding: 2px 0;\"\u003e\u003cstrong\u003eXante X32\u003c\/strong\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv style=\"grid-column: 1\/-1; height: 8px;\"\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv style=\"color: #d36b03; padding: 2px 0;\"\u003e\u003cstrong\u003eYuxunda SGH0606\u003c\/strong\u003e\u003c\/div\u003e\n\u003cdiv style=\"color: #d36b03; padding: 2px 0;\"\u003e\u003cstrong\u003eYuxunda SGH0609\u003c\/strong\u003e\u003c\/div\u003e\n\u003cdiv style=\"color: #d36b03; padding: 2px 0;\"\u003e\u003cstrong\u003eYuxunda SGH1013\u003c\/strong\u003e\u003c\/div\u003e\n\u003cdiv style=\"color: #d36b03; padding: 2px 0;\"\u003e\u003cstrong\u003eYuxunda SGH2513\u003c\/strong\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cp style=\"margin-top: 12px; margin-bottom: 12px;\"\u003eNot sure if this damper fits your printer?
