3. Wipe the sensor with one of the cotton swabs provided in the User Maintenance Kit, slightly dampened with 95% ethanol, to remove dried ink. NOTE: 95% ethanol is not provided in the User Maintenance Kit. If the sensor window is heavily coated with dried ink, you may need to apply some pressure while wiping, helping the cotton to absorb the ink. Continue cleaning with fresh swabs until the cotton stays clean and the sensor window looks clean. When reflecting ambient light, a clean sensor shows a bluecolored reflection that should extend uniformly across its whole surface. You can see this reflection by moving closer and slightly changing your angle of view. 4. Remove the 95% ethanol and the cotton swabs from the vicinity of the printer. 5. Wait three or four minutes to let the ethanol evaporate, before turning on the printer and reloading the substrate. Clean and lubricate the carriage rail NOTE: Under some workflows, or/and site conditions such as in warm ambient temperature, which are above the printer's operation specification (above 30ºC(86ºF)), or if there is significant ambient dust; the lubrication of the slider rods can be reduced or affected, which can in turn affect the performance of the printer. NOTE: A visual explanation of the procedure to clean and lubricate the carriage rail can be found here: http://www.hp.com/go/L26500/videos 1. To gain access to the carriage, go to the front panel and select the icon, then select Carriage rail lubrication. 2. Unlock and open the window. 20 Chapter 4 Hardware maintenance ENWW
