5Ć2 Functional Overview C3187Ć90000 Loading the Media The media load path begins with the entry platen, which provides a loading surface.
5Ć3 Functional Overview C3187Ć90000 The mediaĆnotĆloaded state can be summarized as follows: Media: not inserted or has not yet reached the primary flag Primary flag: vertical position (id.
5Ć4 Functional Overview C3187Ć90000 Secondary flag Primary flag Photo sensor window Media inserted.
5Ć5 Functional Overview C3187Ć90000 Secondary flag Primary flag Photo sensor window Media inserted Leading edge.
5Ć6 Functional Overview C3187Ć90000 Secondary flag Primary flag Photo sensor window Media inserted Leading edge of media Drive roller slow .
5Ć7 Functional Overview C3187Ć90000 Advancing the Media The media is advanced by the media drive (X Ćdrive) system. Components include: D Media motor (X Ćaxis motor) D W orm pinion and helical driveĆroller gear D Drive roller (Illustration ' page 10Ć23.
5Ć8 Functional Overview C3187Ć90000 Providing a F orce on T op of the Media The bail provides a normal force on top of the media. (Illustration page 10Ć25.) When the pinchĆwheels grip the media and the drive roller advances it, the plotter raises the bail.
5Ć9 Functional Overview C3187Ć90000 Stretching the Media The overdrive roller stretches the media slightly as it is moved through the plotter . It thus reduces bubbling and media cockle caused by media expansion due to the absorption of waterĆbased ink into the media.
5Ć10 Functional Overview C3187Ć90000 Detecting the Media Edges The plotter detects the left and right media edges using the line sensor located on the carriage.
5Ć11 Functional Overview C3187Ć90000 Providing Ink (Carriage Illustration ' page 10Ć21) The plotters use two HP DeskJetĆtype cartridges, each containing 50 nozzles. The cartridges are staggered such that two nozzles on each one are not used.
5Ć12 Functional Overview C3187Ć90000 The geometry of the nozzle is important to maintain drop shape and direction. The distance of the head from the writing surface can determine image sharpness.
5Ć13 Functional Overview C3187Ć90000 Producing an Image The plotters are raster based. They plot using dots to represent the data.
5Ć14 Functional Overview C3187Ć90000 Each dot produced by a 300Ćdpi cartridge has a diameter of 0.0055 in. The dot size must be larger than 1/300th of an inch (0.0033 in.) so that when a singleĆdotĆwide line is printed, dots overlap and the line appears to be continuous.

5Ć16 Functional Overview C3187Ć90000 Aligning the Cartridges The cartridgeĆalignment system is composed of D Stepper motor D Adjustment linkage D Adjustment cam D Adjustable cartridge chute D Carriage drive (Illustrations ' pages 10Ć15 and 10Ć21.
5Ć17 Functional Overview C3187Ć90000 Servicing the Cartridges (Illustration ' page 10Ć17.) V arious important cartridgeĆmaintenance operations are .
5Ć18 Functional Overview C3187Ć90000 Ink evaporates if you expose nonĆfiring nozzle plates to the open environment. V apor loss changes the physical properties of the ink remaining in the area of the nozzle plate. The ink may form viscous plugs that fully or partially clog nozzles.
