NOTE: Only substrates at least 51 cm (20 in) wide can be calibrated. The calibration process is fully automatic and can be performed unattended after you have loaded substrate of the type you wish to calibrate. The process takes about 15 minutes and consists of the following steps: 1. The color calibration test chart is printed, which contains patches of different densities of each ink used in your printer. 2. The test chart is scanned by the HP Embedded Spectrophotometer. If the scan cannot be completed successfully, a message is displayed on the front panel; see System error codes on page 238. 3. From the measurements made by the spectrophotometer, the printer calculates the necessary correction tables to apply to your print jobs, for consistent color printing on that substrate type. You can check the color calibration status of your substrate by tapping on the front panel. ● Recommended status indicates that this substrate has never been calibrated. In this case, the factorydefault color tables will be applied to print jobs, as there is no reference state defined. After one or more color calibrations have been performed, tapping the Reset button returns the status to Recommended. ● OK status indicates that a color calibration has been performed successfully at least once on this substrate, and therefore a color reference state is defined. ● Obsolete status indicates that the last color calibration may be out of date. For instance, color calibration status is set to Obsolete whenever a printhead is replaced. The color reference state remains defined. ● N/A indicates that this substrate cannot be color-calibrated. NOTE: Generic substrates cannot be color-calibrated, although such substrates may be suitable for color calibration. You can color-calibrate clones of most generic substrates. TIP: If color calibration fails, it is worth trying again. TIP: If the first color calibration of a new substrate fails, tap the Reset button before trying again. Color consistency between different 700 and 800 series printers It is possible to cross-calibrate color between two or more printers for particular substrates. After crosscalibrating a given substrate, you can expect to get very similar prints from either printer when using the same substrate. 1. Choose printer A to be the reference printer, and use it to perform color calibration on the substrate in question. See Color calibration on page 101. 2. Export the calibrated substrate preset. See HP Media Locator on page 93. 3. Import the substrate preset of step 2 into printer B. See HP Media Locator on page 93. 4. Color-calibrate the preset with printer B.
