Media not Loading. Mispositioned trailing cable: Make sure that the trailing cable is positioned under the plastic tabs at the back of the carriage cover, and not above them. Otherwise, the following happens: 1 During plotter initialization, the trailing cable prevents the carriage from reaching the leftĆhand stop, and all YĆaxis references are shifted to the right. 2 During media loading, the line sensor on the carriage searches for the right media edge at a position too far to the right, and the plotter rejects the media. 3 The plotter does not park the carriage correctly in the service station, so the cartridges are not correctly capped. The ink dries in the nozzles, and the primer has no effect. Excessive loading force: When you begin to load media and push it into the plotter with too much force, too large a buckle forms in the media. The roller is then not able to correctly grasp the media and misaligns it. Instead, load the media so that the sheet buckles only slightly. Loading media too slowly: If you push the media into the entry platen too slowly, the media sensor instructs the roller to move before the media has reached the roller. This can cause misalignment of the media. Instead, push the media in briskly. See the mediaĆloading guide C3190Ć90162 for more information on the trick to loading media correctly every time.
