The printer needs to calibrate to determine how much toner is delivered by each cartridge and hence the colour balance.

HP CLJ 2600 series printers automatically calibrate at various times. Calibration settings can be adjusted.

Image density changes might be caused by environmental differences or aging print cartridges The printer uses image stabilization control to deal with this automatically. Calibration can also be requested.

The printer does not interrupt a print job to calibrate. It waits until the job is complete before calibrating or cleaning. When the printer is calibrating, printing is suspended for the time required to complete the calibration task.
