Roland Machine RF-640 Used The shop has been closed, and a maintenance worker was brought in to empty its ink, clean it, and put maintenance oil in the machine to maintain its quality and efficiency. It has been stored in the warehouse for 4 months, clean, working, and wrapped. The machine is strong and practical, but the owner's and workers' circumstances led to it being put aside. For sale to the highest bidder. May God compensate and bless everyone.
