Roland Soljet EJ-640

Turn up the volume on your production

With dual staggered print heads, an integrated tri-heater system, strong industrial design and high capacity 1-litre ink cartridges available in 4 or 7 colour configurations, the EJ-640 is built for optimum performance in a high volume production environment. In a mirrored CMYK ink configuration, the EJ-640 can achieve speeds of upto 102m2/h. The EJ-640 utilises specifically designed EJ Ink, developed alongside the machine to offer end users substantially lower operating costs for high volume and long run print jobs

With a particular focus on high volume business, the specifically designed high strength media shaft holds heavy media rolls securely  - and a newly developed feed Adjuster ensures the smooth progression of media through the printer and onto the take-up system. In addition the powerful tri-heater dries ink quickly to allow immediate take up, allowing for immediate storage if required. In 4-colour CMYK mode, up to two litres of ink can be loaded for each colour for optimum efficiency. In combination with the Roland Ink Switching System, continuous printing is possible without any worry of ink running out. Unattended operation is further facilitated by Roland OnSupport, which sends email to your smart phone, tablet or computer to notify the machine operator when a job is finished or running low.
