Calibrating the printer

The HP Color LaserJet CP4005 Series printer automatically calibrates and cleans at various times to maintain the highest level of print quality. The user might also request the printer to calibrate via the printer’s control panel, using QUICK CALIBRATE NOW or CALIBRATE NOW located in the PRINT QUALITY menu. QUICK CALIBRATE NOW is used for color tone calibration and takes about 65 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 4 minutes and 20 seconds. If color layers (black, magenta, cyan, and yellow) on the printed page seem to be shifted from one another, CALIBRATE NOW should be run.

The HP Color LaserJet CP4005 Series printer incorporates a new feature to skip calibration when appropriate, thereby making the printer available more quickly. For example, if the printer is turned off and on quickly (within 20 seconds), calibration is not needed and is skipped. In this case, the printer will reach the Ready state approximately 1 minute sooner.

While the printer is calibrating and cleaning, the printer will pause printing for the amount of time it takes to complete the calibration or cleaning. For most calibrations and cleaning, the printer will not interrupt a print job, but will wait for the job to complete before calibrating or cleaning.

Repetitive defect ruler

If defects repeat at regular intervals on the page, use this ruler to identify the cause of the defect. Place the top of the ruler at the first defect. The marking that is beside the next occurrence of the defect indicates which component needs to be replaced.
