Troubleshooting process Determine the problem source The following table includes basic questions to ask the customer to quickly help define the problem or problems. General topic Environment Paper Input trays Print cartridge Transfer roller and fuser Print-cartridge door and duplex door (duplex models only) Condensation Miscellaneous Questions ● Is the product installed on a solid, level surface (± 1°)? ● Is the power-supply voltage within ± 10 volts of the specified power source? ● Is the power-supply plug inserted in the product and the outlet? ● Is the operating environment within the specified parameters? ● Is the product exposed to ammonia gas, such as that produced by diazo copiers or office cleaning materials? NOTE: Diazo copiers produce ammonia gas as part of the coping processes. Ammonia gas (from cleaning supplies or a diazo copier) can have an adverse affect on some product components (for example, the print-cartridge OPC). ● Is the product exposed to direct sunlight? ● Does the customer use only supported paper? ● Is the paper in good condition (no curls, folds, or distortion)? ● Is the paper stored correctly and within environmental limits? ● Is the amount of paper in the tray within specifications? ● Is the paper correctly placed in the tray? ● Are the paper guides aligned with the stack? ● Is the print cartridge installed correctly? ● Are the transfer roller and fuser installed correctly? ● Is the print-cartridge or duplex door closed? ● Does condensation occur following a temperature change (particularly in winter following cold storage)? If so, wipe affected parts dry or leave the product on for 10 to 20 minutes. ● Was a print cartridge opened soon after being moved from a cold to a warm room? If so, allow the print cartridge to sit at room temperature for 1 to 2 hours. ● Check for and remove any non-HP components (for example, a print cartridge) from the product. ● Remove the product from the network and make sure that the failure is with the product before beginning troubleshooting. 116 Chapter 3 Solve problems ENWW
