DC controller (new or previously installed in another printer)
After replacing the DC controller, 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 (for example, the duplexing option, page counts,
and serial number) can be restored from the flash memory card to the NVRAM.
After installing the replacement DC controller, perform a quick calibration procedure three
times.See the
Print quality menu table.
