To prevent a printer downgrade situation:
●
Do not reuse a DC controller that has been installed in another printer even if that DC controller
was only used for one power cycle. If a DC controller has been installed in a printer and the printer
was turned on, the DC controller is considered used.
●
Do not replace the formatter and the DC controller at the same time.
Replacing the formatter and the DC controller
CAUTION Follow the steps exactly in the order they are presented when you replace the
formatter and the DC controller on the same printer. Failure to follow these steps correctly might
result in additional service or printer replacement.
1. Print a configuration page. See Configuration pages on page 283.
2. Turn the printer off.
3. Remove the formatter and install the new formatter.
4. Turn the printer on and wait five minutes after reaching the Ready state.
NOTE A five-minute wait time is required at certain points in the parts replacement process
to allow the NVRAM settings to be written.
5. Turn the printer off.
6. Remove the DC controller and install the new DC controller.
7. Turn the printer on and wait five minutes after reaching the Ready state.
NOTE A five-minute wait time is required at certain points in the parts replacement process
to allow the NVRAM settings to be written.
8. Print a configuration page and, if possible, verify the settings against the original settings on a
recent configuration page. See
Configuration pages on page 283. Specifically, verify the printer
series and bundle (such as 5200n, 5200dtn) and the printer serial number. If the printer
configuration settings differ from the settings that existed before the parts were replaced, the printer
settings need to be reset. This can be done with help from HP ATS.
