Moisture on the Printer Users should use the Printer in an environment between 5% and 95% relative humidity. To recover from moisture condensation, turn the Printer Off, and, using the main roller as a reference, wait until the Printer is completely dry before using it again. Noisy Carriage Bushing To prevent noisy movement of the carriage, remove aluminum or dust particles from the bushing at the back of the carriage, and from the slider path along which the bushing moves. Belt Swelling To prevent new belts from swelling incorrectly, keep them in their bags with dissicant until you need to install them. Cleaning the Printer To maintain the Printer in good operating condition, keep it free of dust accumulation, ink, and other contamination. Cleaning intervals are determined by the Printer environment and by the types of Printer supplies used. WARNING Disconnect the Printer from the power source prior to performing any cleaning. DO NOT allow liquid to run on to electrical components or circuits, or through openings in the enclosure, as this can create a shock hazard leading to death or injury. General Cleaning Proper general cleaning should include the following: 1 Blow away dust accumulation with compressed air if available. 2 Clean the outer surface of the Printer with a damp sponge or cloth. Use a mild soap and water solution if necessary. Do not use abrasive cleaners. 3 Wipe the Printer dry with a soft lint-free cloth. 9-2 HP DesignJet CP Series Printers Preventive Maintenance
