Always print a configuration page before and after (wait five minutes after the printer power is turned on) installing the parts in the above list to verify that the printer configuration information is restored from the compact flash memory to the NVRAM. Formatter and DC controller WARNING! Do not replace the formatter and the DC controller at the same time. If the formatter and DC controller must both be replaced, install a replacement formatter first and make sure that you install the compact flash memory from the removed formatter on the replacement formatter before you turn the printer power on. If the formatter and DC controller need to be replaced, install a replacement formatter first. The HP Color LaserJet 4700 and HP Color LaserJet CP4005 printers store printer configuration information in the compact flash memory. The compact flash memory from the removed formatter must be installed on the replacement formatter, so that printer configuration information (for example, the duplexing option, page counts, and serial number) can be restored to the formatter and DC controller. After replacing the formatter and installing the compact flash, turn the printer power on. When the Ready message displays on the control panel, you must wait five minutes before using the printer so that the printer configuration information can be restored from the compact flash memory to the NVRAM. Turn the printer power off, and replace the DC controller. Turn the printer power on. When the Ready message displays on the control panel, wait five minutes before using the printer so that the printer configuration information can be restored from the compact flash memory to the NVRAM. After installing the replacement formatter and DC controller, perform a full calibration procedure three times. See Full Calibrate Now on page 539.
