        Exclusive electroproduction of charmonium in ep collisions has been
        studied with the ZEUS detector at HERA using an integrated luminosity
        of 84 pb^{-1}. The study for Q^2 > 2 GeV^2 extends the W range of 
        the measurement to 30 < W < 220 GeV.  The cross section in the low-Q^2
        regime, 0.2 < Q^2 < 0.7 GeV^2, is measured for the first time using 
        about 70 pb^{-1} of integrated luminosity. The charmonium states were 
        identified using the leptonic decay channels.  Cross sections have 
        been measured as a function of Q^2 and W. The ratio of the cross 
        section sigma(J/psi)/sigma(rho) as a function of Q^2 is also presented.
        The angular distribution of the decay leptons has been analysed and 
        compared to the expectations based on the s-channel helicity 
        conservation hypothesis.
