Abstract
An imaging device includes a printhead and a detector configured to generate an electronic signal indicative of an increase in height in a portion of a media before such portion of the media passes the printhead. The imaging device also includes a vacuum source operable to pull the portion of the media having the increase in height away from the printhead so the media does not impact the printhead. The vacuum source is positioned below an opening in a platen opposite the printhead.
Claims16
A method of operating an imaging device comprising:
- detecting with a detector that generates an electrical signal indicative of an increase in height in a portion of media that is present in the portion of the media before the portion of the media reaches a printhead of the imaging device;
- and
- activating with a controller in response to the controller receiving the generated electrical signal from the detector a vacuum source to pull the portion of the media having the increase in height away from the printhead as the portion passes by the printhead.
A printer comprising:
- at least one printhead configured to eject ink onto media as the media passes by the at least one printhead;
- a detector configured to generate an electrical signal indicative of an increase in a height in a portion of the media that is present in the portion of the media before the portion of the media reaches the at least one printhead;
- a vacuum source configured to pull the portion of the media having the increase in height away from the at least one printhead as the portion of the media passes the at least one printhead;
- and
- a controller operatively connected to the detector and the vacuum source, the controller being configured to operate the vacuum source and pull the portion of the media having the increase in height away from the at least one printhead in response to the detector generating the electrical signal indicative of the increase in height of the portion of the media that is present in the portion of the media before the portion of the media reaches the at least one printhead.
