HP LaserJet MFP M630 - Removal and replacement: Formatter
This document provides the procedures to remove and replace the formatter.

Mean time to repair: 10 minutes
Service level: Intermediate
To replace the formatter, remove the hard-disk drive (HDD) or solid-state memory (SSM) storage device, the DIMM, and the fax printed-circuit assembly (PCA) (if installed) from the defective formatter and then install them on the replacement formatter.
Before performing service
Turn the printer power off
-
Disconnect the power cable.
Warning:To avoid damage to the printer, turn the printer off, wait 30 seconds, and then remove the power cord before attempting to service the printer.
This part contains components that are electrostatic discharge (ESD) sensitive. To reduce the possibility of ESD damage,
always touch the sheet-metal chassis to ground yourself before touching an ESD sensitive part.
Do not replace the formatter, DC controller, and hard-disk drive simultaneously during a single printer servicing. Doing so might cause the printer to become unstable or inoperable.

No special tools are required to install this kit.
After performing service
Turn the printer power on

Use the power switch to turn the power on.
Tip:If the product does not initialize when the power is turned on, make sure that the memory DIMM is correctly installed.
To verify that the formatter is correctly installed, observe the following functions of the LEDs on the formatter:
-
The heartbeat LED (callout 1) illuminates if the formatter is functioning correctly.
-
While the product is initializing, the heartbeat LED illuminates solid red for about one second, and then turns solid green for about twenty seconds.
-
After the initialization sequence is complete, the heartbeat LED blinks continuously if the printer is functioning correctly.
-
-
The connectivity LED (callout 2) indicates that the formatter is completely seated. It illuminates green when the product power is turned on and stays green if the formatter is properly seated.
If the LEDs do not correctly function, turn the product power off, remove the formatter, and then reinstall it (make sure that the formatter is fully seated before tightening the thumbscrews).
