HP CM8060 Color MFP Kundendienst Handbuch Seite 213

About once a day at the end of a job, the MFP checks the pens for defects and attempts to resolve any
defects. If no defect is found, this process only takes about 2 minutes to complete. If defects are found,
it will take an additional 3, 7, or 12 minutes (3 stages) to recover from the defects, depending on the
severity. When the MFP is checking for defects, no message is displayed unless the user interrupts, for
example to send a print job. In this case, the MFP displays the "Calibrating" message to notify the user
while it attempts to cancel the process which takes at least 30 seconds to complete. In this situation,
the user will see the "Calibrating" message for about 30 seconds before printing can begin. If the MFP
successfully cancels this process, it will reinitiate the process again 4 hours later.
If the process is not interrupted, the MFP completes the checking of the pens silently. If defects are
found, it will attempt to recover from the defects. During this recovery phase, the message "Calibrating"
will be displayed on the LCD screen. How often the checking process resulting in the recovery process
depends on the health of the pens-- worst case estimate is approximately once a week.
Servicing at scheduled time set by administrator
The servicing time can be set by the device administrator using the control panel, Embedded Web
Server, or Web Jet Admin. It is recommended to select a time when the system will be powered on and
is least likely to be used so that the servicing routines do not interrupt customer usage of the device. By
default, the scheduled calibration time is 3:00AM. The scheduled servicing is performed daily to maintain
print quality and print speed. When the calibration is initiated, the MFP displays the "Calibrating"
message. This message can stay on the screen for 3 to 15 minutes depending on the types of pen
servicing performed, but it can be interrupted by an incoming print job. If the daily calibration can not be
completed during its scheduled time, such as interrupted by a user job or an out of ink condition, the
calibration is postponed, and then reinitiated at the next opportunity within 2-4 hours.
In order for the daily calibration to execute, the device must be powered ON during the time that the
calibration is scheduled. If the device is set to Sleep during this time, it will wake to perform the
maintenance, and then go back to sleep as configured by the sleep interval. If the device is powered
OFF when the calibration is scheduled to execute, the calibration will be initiated at the next opportunity,
such as when the pens go into the capped position after a print job. If a device is frequently powered
off over night, a different calibration time (not the 3:00 AM default) should be selected during a time
when the device will be powered ON and least likely to be in use.
