Gestetner fax supplies use 430-series numbers, and this section covers 430228 along with 430347 black toner. The code is short enough to be printed on the end of the cartridge, which is usually easier to read than the label inside the machine. There is no colour option on these models, so black toner is the only consumable you need to track.
Ricoh Family Fax Supplies
The 430347 code is a good illustration of how closely the Ricoh group brands overlap, since it also appears in the Lanier and Savin fax listings for the same part. If your machine wears a Gestetner badge but the number does not appear here, those sibling sections are the first place to search.
