ABSTRACT:
A mechanism actuates a sheet feed means after a predetermined length of time after a control lever is moved to a print position, thereby allowing sufficient ink to be transferred to a transfer roller such that the first sheet printed has the same density as subsequent sheets. The mechanism comprises a ratchet and a pawl, the pawl being reciprocatingly driven in synchronism with the transfer roller and advancing the ratchet from a reset position to a position in which it engages with a sheet feed control linkage to activate the sheet feed means in a predetermined number of reciprocations corresponding to the predetermined length of time.
