Abstract
A recording medium holddown apparatus for holding down a recording medium traversing along a path on a platen in a post-printing area of a printer. The recording medium holddown apparatus includes a first and second holddown member located above the platen to force a recording medium having any curl flat against the platen to thereby prevent problems associated with curl such as contamination of the printhead nozzles, ink smear, paper misregistration, and carriage hangup. In addition to the holddown members, a first and second runner are disposed on a carriage carrying the printhead across the recording medium for printing. The first and second runners have upturned ends to intercept any curl of the recording medium to further avoid problems associated with recording medium curl.
