An exposure station of an electrophotographic printer (e.g. a reader-printer) comprises means defining a downwardly inclined support for a copy sheet and stop means for the sheet adjacent to the lower extremity of the support, the stop means being movable between operative and inoperative positions, in the former of which it supports the copy sheet against sliding down the support. The stop means comprises a lower stop means and an upper stop means, the lower stop means being effective in a transverse central region of the support and the upper stop means being in two parts, one lying on each side of said central region.
