Always print a configuration page before and after installing the formatter or DC controller to verify that the printer configuration information is restored from the CompactFlash memory to the NVRAM. Wait five minutes after the printer power is turned on before printing the after installation configuration page. 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 CompactFlash memory from the removed formatter on the replacement formatter before you turn the printer power on.

After replacing the formatter and installing the flash memory, turn the printer power on. When the READY message appears on the control-panel display, you must wait five minutes before using the printer so that the printer-configuration information can be restored from the flash memory to the NVRAM.
