49.38.07 error (4a04)

I started having the above errors and decided to do a firmware update. The process was not as easy as I thought but it was simple:

1. Download the firmware from here

2. Extract and save firmware file (eg: cljCP5525fw_2304070_439646.bdl) to USB thumb drive

3. The technical part: remove the two screws at the back of the printer as shown below:

4. Pull out the formatter (towards you)

5. Insert USB drive on formatter (board)

6. After inserting USB drive on board, replace formatter and turn on printer

7. Go to the printer's Control Panel display 

8. Now hit the HOME button and scroll to DEVICE MAINTENANCE -> USB Firmware Upgrade

9. Select the firmware and hit OK... DO NOT UNPLUG the printer while it is upgrading.

After the process completes, the device will restart and initialize.... after that, the error will go away.

Hope this was helpful....

and 10... do not forget to remove USB thumb drive before closing formatter.
