Abstract
A feed mechanism for moving a record member into a printing position in which a single control solenoid is energized to enable a pair of drive rollers to move a multi-form record member from a holding position to a printing position. Operation of the solenoid further moves a platen member into engagement with the record member which is spring urged to enable the platen to apply a force on the record member. The force on the platen is selected to compensate for the thickness of the record member allowing a dot matrix printer to print satisfactorily on record members of varying thicknesses. The drive rollers are normally positioned to locate a record member in a validating printing position. Spring means are associated with the drive rollers to engage and hold the record member in a printing position during the operation of the solenoid.
