Today while printing our SP 20 started making a metallic dragging sound. It stops when the motor turns off and gets louder when the carriage is at the feed board with the rollers down, when there is pressure on the ink drum. I suspect that it’s because the chain is stretched or loose and is hitting something but I can’t see well enough to confirm. I kept the motor on to quickly clean the press but want to solve this before printing again – I don’t want anything to get damaged. I’ve attached a few videos IMG_0442 IMG_0445
I’m not sure how to best access the motor if that is required to get to the chain. Or where to get a replacement chain if need be.
Any help is welcome! Thank you!
