Calibrating the printer

The HP Color LaserJet 5550 printer automatically calibrates and cleans at various times to
maintain the highest level of print quality. The user may also request the printer to calibrate
via the printer’s control panel, using QUICK CALIBRATE NOW or FULL CALIBRATE NOW
located in the CALIBRATION and PRINT QUALITY menu. QUICK CALIBRATE NOW is
used for color tone calibration and takes about 90 seconds. If color density or tone seems
wrong, Quick Calibration can be run. Full Calibration includes the Quick Calibrate routines
and adds Drum Phase Calibration and Color Plane Registration (CPR). This takes about 3
minutes and 30 seconds. If color layers (cyan, magenta, yellow, black) on the printed page
seem to be shifted from one another, Full Calibration should be run.

The HP Color LaserJet 5550 printer incorporates a new feature to skip calibration when
appropriate, making the printer available more quickly. For example, when the power switch
is turned off, then on again quickly, calibration is not needed and will be skipped. This saves
approximately one minute in time to be ready.

The printer may pause printing while it is calibrating or cleaning. When possible, the printer
will wait for the job to complete before calibrating or cleaning.
