FREQUENTLY ASKED QUESTIONS
Frequently Asked Questions — Roland Eco-Solvent EJ
The Roland SolJet EJ-640 is a 64-inch wide-format eco-solvent inkjet printer. It uses Roland’s Eco-Solvent EJ ink system (OEM code: EJ) — a separate ink family from Eco-Sol MAX (ESL3/ESL4/ESL5) and Eco-Xtreme (AI2/AI3/AI4). Confirm your printer is the EJ-640 and your current cartridge shows OEM code EJ before ordering.
Eco-Solvent EJ and Eco-Sol MAX are different Roland ink families for different printer lines. The EJ ink is for the SolJet EJ-640. Eco-Sol MAX (ESL3) is for older SOLJET SP/XC and VersaCAMM VS/VP/SP printers. Eco-Sol MAX 2 (ESL4) is for the SolJet Pro 4 XR-640 and VSi series. These are not interchangeable — always confirm by reading the OEM code on your current cartridge.
No — unless your VersaCAMM specifically uses OEM code EJ. Most VersaCAMM printers use ESL3, ESL4, or ESL5. The EJ ink is confirmed only for the SolJet EJ-640. Using the wrong ink can damage your printhead. Confirm your OEM code before ordering.
No. All STS eco-solvent inks are non-returnable. Confirm your printer model and the correct OEM ink code before ordering. Call (512) 454-0505 or email [email protected] with your printer model to confirm compatibility.
No. STS eco-solvent inks are formulated to be a virtual match to the original OEM inks. Install them exactly like OEM — no purging, no profile changes, no downtime.
All STS inks are manufactured in the USA. Orders drop ship directly from STS in Florida — you receive current-production ink, not warehouse-aged stock.
