Calibrating the printer
The printer automatically calibrates at various times. You can adjust the calibration settings
by using the HP Toolbox.
Environmental differences, aging print cartridges, aging toner, and an aging imaging drum
might cause fluctuations in image density. The printer accounts for this with image
stabilization control. The printer automatically calibrates at various times to maintain the
highest level of print quality. You can also request a calibration by using the HP Toolbox.
The printer does not interrupt a print job to calibrate. It waits until the job is complete before
calibrating or cleaning. While the printer is calibrating, it pauses printing for the time that is
required to complete the calibration.
