Hi guys. Have just started to get these machines coming in for PCDU parts and new developer. Have noticed as per photo this rubber strip fall's off like on the 7501 Developers. Due to me starting on Ricoh's towards the end of life of the 7501's i just let them drop off or take them off. I'm looking for what you guys do with these? Special kind of Glue? Double sided sticky tape? Cheers
