A group $G$ is **residually finite** if for each element $g\in G$ there exists a (surjective) homomorphism $f_g: G \rightarrow H_g$ such that $H_g$ is finite and $f_g(g)\ne 1$.

Consider the weaker condition where a finitely generated group $G = \langle x_1,\dots,x_n\rangle$ has the property that for each $x_i$ in this fixed generating set there exists a homomorphism $f$ onto a finite group $H$ such that $f(x_i)\ne 1$.

To see this is a weaker condition, assume $G$ is residually finite let $f:G\rightarrow H_{x_1}\times\cdots \times H_{x_n}$ by $f(g)=(f_{x_1}(g),...,f_{x_n}(g))$.

However, is this condition strictly weaker? That is is there a finitely generated group $G$ with a fixed generating set $X$ such that for each element of $x_i \in X$ there is a homomorphism onto a finite group $H_{x_i}$ but $G$ is not residually finite?
