3. Apply a few drops of oil directly to the slider rod on either side of the carriage. 4. Close the printer window. Maintain the ink cartridges During the normal lifetime of a cartridge, no specific maintenance is required. However, in order to maintain the best print quality, you should replace a cartridge when it has reached its expiration date, which is the manufacturing date marked on the cartridge plus 30 months. Perform preventive maintenance During the life of your printer, components that are used constantly can wear out. To avoid having these components degrade to the point that the printer breaks down, the printer keeps track of the number of cycles that the printer carriage makes across the axis of the printer, and also monitors the total quantity of ink used. The printer uses these numbers to track the need for preventive maintenance, and displays one of the following messages on the front panel: ● Maintenance #1 required ● Maintenance #2 required These messages mean that some components are nearing the end of their lives. You can continue printing for quite some time, depending on your use of the printer. However, HP strongly recommends that you contact your customer service representative and arrange for a preventive maintenance visit. The service engineer can then replace the worn parts onsite, which will prolong the life of the printer. The benefits of arranging a service engineer's visit when these messages appear on the front panel are twofold: ● The printer components can be replaced at a time that is convenient for you, and so will not disturb your daily workflow. ● When the service engineer performs a preventive maintenance visit, replaces several parts at once. This eliminates the need for repeat visits. Move or store the printer If you need to move your printer or store it for an extended period of time, prepare it correctly to avoid possible damage. 1. Do not remove the ink cartridges, printheads or printhead cleaners. 2. Make sure that no paper is loaded. 114 Chapter 11 Maintain the printer ENWW
