Gestetner machines are Ricoh-built, so the consumables here are listed under Ricoh part numbers. The 8417xx block covers black, cyan, magenta and yellow toner at 31k and 22.5k yields, 841285 and 841286 add 17k yellow and magenta, and 406997 is a 15k black. Imaging parts include the D144-2250 black drum, the D144-2252 color drum and the B190-9510 photoconductor.
Developer Assemblies and Cross-Brand Parts
The B116 numbers are developer assemblies rather than toner, supplied per color, and are replaced far less often than a cartridge. Several parts here are explicitly listed as compatible across Ricoh, Savin, Gestetner and Lanier, including 841295 black at 10k, so a number that is missing from one brand section may well appear under another.
