Cleaning all of the 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. NOTE: HP recommends that you purge the ink from the printheads before printing a job if the printer has been turned off for more than six weeks or if you are experiencing inconsistent colors from print to print after long storage periods. Purging the ink from the printheads helps to ensure maximum color consistency; it is not a remedy for poor printhead health. 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 accessed or replaced. In the case of a paper jam, if you have used a custom paper, or if you are experiencing problems with color accuracy; you might need to align the printheads. See Align the printheads on page 71. NOTE: If you experience a paper jam, HP recommends that you reinsert the printheads and align the printheads. TIP: Use the same paper you intend to print on to align the printheads. Photo paper is recommended for the best results. Plain; bond; and thin, coated papers are acceptable, but provide marginal results. WARNING! Colored papers, 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 paper is loaded, press the Cancel key on the front panel. CAUTION: Do not print if the printhead alignment process has been canceled. 2. Load the paper you want to use. Photo paper is recommended for the best results. WARNING! Colored papers, 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.
