However, the one being removed has black end, says genuine Ricoh MP C3502 & MP C5502.. The one we are trying to install has brown end. The only difference that I can see is the tab at the 2 o'clock position on the black one is smaller. Both install completely. The one with the brown end I have used these for years with no issues. When reinstalling the black ended one it is fine, switch to the brown ended one, toner cartridge not set correctly. I have pulled apart the rear of machine and nothing seems to be amiss. Any ideas?
