Replacement parts configuration (HP Color LaserJet 5550
models)
When the following parts are replaced, perform the procedures shown in this section.
● Both the formatter and the DC controller
● Formatter (new or previously installed in another printer)
● DC controller (new or previously installed in another printer)
Note
The HP Color LaserJet 5550 models store printer configuration information in the flash
memory card. Always print a configuration page before and after (wait five minutes after the
printer power is turned on) installing these parts to verify that the printer configuration
information is restored from the flash memory card to the NVRAM.
Both the 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 to that
you install the flash memory card from the removed formatter on the replacement formatter
before you turn the printer power on.
If both the formatter and the DC controller need to be replaced, install the replacement
formatter first. The HP Color LaserJet 5550 models store printer configuration information in
the flash memory card. The flash memory card 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
the DC controller. After replacing the formatter and installing the flash memory card, 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 card to the NVRAM.
Then replace the DC controller. Turn the printer power off, and replace the DC controller.
Turn the printer power on. When the Ready message appears on the control panel display,
wait five minutes before using the printer so that the printer configuration information can be
restored from the flash memory card to the NVRAM.
After installing the replacement formatter and DC controller, perform a full calibration
procedure three times. See the
Print quality menu table.

After replacing the formatter and installing the flash memory card, turn the printer power on.

Note
The transfer kit page count is not reset by replacing the formatter.
After installing the replacement formatter, perform a full calibration procedure three times.
