Toner refill plug for melted hole
Precisely matched to the size of hole you'll make with the
electric melting tool
Note that to get it sealed right, this plug must be used in conjunction with a sealant at the moment of insertion.
Suitable sealants include bathroom sealant, Copydex and the silicon glue.
Not suitable for the HP M254 family, HP M102 family or any cartridge where a patch is specified in the
instructions rather than a plug.
