Ricoh Aficio MP 161 PMB12990K Replacment Instructions

Below you will find the illustrated Ricoh Aficio MP 161 PMB12990K Replacement instuctions. Yeah, I know, these machines are getting on in age. Excuse me, I just happened to look up the instructions, saw they were pretty straight forward, and found out you can still get the parts. So, I figured what the heck.

While these machines are old, they have a bottled toner. Why is that important? Just ask your customer how much they are paying for those toners. Yeah, they are dirt cheap, therefore these machines are surprising economical to run so some customers like to keep them around as long as possible.
