5. They sell under the Reorder 6R1179 for around 75 per cartridge The C123 128 133 cartridges look the same but they yield 30K and sell for 155 6R1184 No doubt the CRUM Customer Replaceable Unit Monitor chip has a different ID so the machine can tell if you put the wrong one in there This machine uses a new type of CRUM instead of using Connectors it uses a radio feedback chip which makes no physical connection at all I can t help but call it the Star Wars chip because it reminds me of the Star Wars figures which came out a few years ago Those toys had a similar technology The figures came with chips and then there was an electronic toy sold which could tell which chip was placed on it and it d play back sound clips relating to the character the chip belonged to They take it a step further in the copiers though the machine can write to the chip as well as being able to read it They have come up with a new name for the Drum Cartridges this time around the Service Manual refer to them as Xero Developer Cartridges They have a yield of 60K and retail for 199 13R589 The C123 128 133 machines use the same cartridge as the C118 M118 Like the Toner Cartridges these Drum Cartridges also use the new Star Wars type of CRUM chip The Fuser is supposed to run for around 175K although I m told many of them require work or replacement considerably before the count runs out According to the parts

Drawn from a pair of ENX Articles written by The Parts Drop Introducing Xerox C118 M118 Scratching the Surface PART J Introduction amp Status Code Meanings for the Xerox CopyCentre C118 amp WorkCentre M118 M118i Xerox C118 These machines are still being placed today by Authorized Dealerships nationwide they re selling strong and I suspect for good reason These models were released originally in 2004 but new ones are still available from Xerox I thought at first that the machines were Fuji Xerox engines but now that I ve seen how the diagnostics work I have my doubts The logic is different from the usual it reminds me more of the Toshiba equivalent machines Xerox has sold in the past So far I m not aware of any crossovers to other makes Folks are telling me that these are machines they want to support so let s get started Physically they are very closely related to the C123 128 133 M123 128 133 amp Pro123 128 133 also the Phaser 5500 however the Status Codes and Diagnostics are surprisingly very different between the two groups of models This article will focus on the C118 style and we ll hit on the C123 style in a future article These machines are rated to handle a volume of up to 50K pages per month and they run 18 pages per minute They range from 1348 for the stripped down version of the C118 to 3249 for a loaded M118i The Toner Cartridges have a stated yield of 11K prints
