Clean the printheads Periodic printhead cleaning is performed automatically, as long as the printer is kept turned on. However, you should clean the printheads if you are experiencing poor image quality and cannot resolve the issues by other methods. This ensures that there is fresh ink in the nozzles and helps to prevents nozzle clogs. If you have printed the printhead status plot, you know which colors are failing. Clean the pair of printheads that are not performing adequately. If you are not sure which printheads to clean, clean all of the printheads. To clean the printheads, go to the printer's front panel and select the icon, select Image quality maintenance > Clean printheads, then select which printheads you want to clean. You can clean all of the printheads or only some of them. The choices are as follows. ● Print test plot ● Clean all ● Clean LC-C ● Clean Y-MK ● Clean LM-M Cleaning all printheads takes about 5 minutes. Cleaning any two printheads takes about 3 minutes. NOTE: Cleaning all printheads uses more ink than cleaning a single pair. Align the printheads Precise alignment between printheads is essential for color accuracy, smooth color transitions, and sharp edges in graphical elements. Your printer has an automatic printhead alignment process which runs whenever a printhead has been reseated or replaced. In the case of a substrate jam, if you have used a custom substrate, or if you are experiencing problems with color accuracy; you might need to align the printheads. See Align the printheads on page 11. NOTE: If you experience a substrate jam, HP recommends that you reseat and align the printheads. TIP: Use the same substrate you intend to print on to align the printheads. WARNING! Colored substrates, glossy canvas, and transparent materials such as translucent bond, clear film, tracing paper, and vellum are not suitable for aligning the printheads. However, if you must perform printhead alignment with a material that is not supported, make sure you use a material with the same thickness as the material you are going to use for printing. Reinsert printheads procedure 1. If the printhead alignment process is running and the wrong substrate is loaded, press the Cancel button on the front panel. CAUTION: Do not print if the printhead alignment process has been canceled. 2. Load the substrate you want to use. Photo paper is recommended for the best results. WARNING! Colored substrates, glossy canvas, and transparent materials such as translucent bond, clear film, tracing paper, and vellum are not suitable for aligning the printheads. However, if you must perform printhead alignment with a material that is not supported, make sure you use a material with the same thickness as the material you are going to use for printing. 72 Chapter 8 Troubleshoot ink-system issues ENWW
