HP Color LaserJet 4730 Multifunction Printer series - Manual (Page 332)

Clean the scanner by wiping it gently with a clean, slightly damp, lint-free cloth. Use an ammonia-based
surface cleaner only when a water-dampened cloth does not clean the scanner glass. Spray or pour the
cleaner onto the cleaning cloth. Do not spray or pour the cleaner onto the scanner glass.
Calibrating the MFP
The MFP automatically calibrates and cleans at various times to maintain the highest level of print
quality. The user might also request the MFP to calibrate via the MFP’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 D-Half color tone calibration. If color density or tone seems
wrong, Quick Calibration can be run. Full Calibration includes the Quick Calibrate routines and adds
Drum Phase Calibration, Color Plane Registration (CPR), and copy parameter calibration routines. If
color layers (black, magenta, cyan, and yellow) on the printed page seem to be shifted from one another,
FULL CALIBRATE NOW should be run.
The HP Color LaserJet 4730 MFP incorporates a new feature to skip calibration when appropriate,
thereby making the MFP available more quickly. For example, if the MFP is powered off and on quickly
(within 20 seconds), calibration is not needed and will be skipped. In this case, the MFP will reach
the Ready state approximately one minute sooner.
While the MFP is calibrating and cleaning, the MFP will pause printing for the amount of time it takes to
complete the calibration or cleaning. For most calibrations and cleaning, the MFP will not interrupt a
print job, but will wait for the job to complete before calibrating or cleaning.
