HP LaserJet M4555 Series Will Not Print

I recently was called out to work on an HP M4555 printer that had some feed issues. Each time the feed issues seemed resolved the printer would print a few pages but then stop.

The printer was receiving information; it said ‘processing’ on the display, acted  like it was going to print but then nothing would happen. Even printing internal information pages from the control panel failed to work. Also, the machine’s control panel was very slow and often times unresponsive to commands.

Whenever I see an odd problem on a new HP printer the first thing I do is check the firmware version and upgrade or replace it. It’s nice that HP has changed the way the firmware is stored and managed. However, with all the new software changes and applications, I’ve seen a drastic increase in firmware related issues.

Warning: Before you update the firmware… if you can, make sure to print off the configuration pages along with the network settings. Most times the newer machines store NVRAM settings in multiple places so restoring settings is typically not needed. However, better safe than sorry. Also, on several occasions, I’ve had to remove the existing firmware and start over. In order to do this you will need to format the hard drive. You can find the format menu in the Administrator section on the hard drive. Once you format the hard drive the machine will give you a 99.xx (firmware installation) error until you reinstall the firmware.

Below are the instructions for the firmware update. I personally like doing it straight from the hard drive, so that is the instruction I’ve included below. On the driver and firmware support page you will find the firmware file and the readme file for additional information on what individual updates fix. Plus, you can find instructions on how to perform the firmware update through the control panel in normal function mode. Click on the link below.


Firmware Update Instructions from Start Up

1. Copy the firmware .bdl file to a portable thumb drive. (Not all thumb drives work. I’ve talked to HP’s internal tech support and they recommend 2 gig or smaller thumb drives. That’s not saying others won’t work. That is just what they have recommended to me.)

2. Turn the printer ON.

3. Press the Stop button when the Ready, Data and Attention LEDs illuminate solid.

4. Press the 9 Key to highlight Administrator, and then press the 6 key.

5. Press the 9 key to highlight Download, and then press the 6 key.

6. Insert the portable thumb drive with the Firmware .bdl file on it.

7. Press the 9 Key to highlight USB Thumbdrive, and then press the 6 key.

8. Press the 9 key to highlight the Firmware .bdl file, and then press the 6 key.

9. When the message Complete appears on the control panel display, press the Back button 3 times.

10. When the message Continue appears on the control panel display, press the 6 key.

11. The printer will continue to boot to the Ready state.

After I installed the new firmware update everything was back up and running the way it should. Like I keep saying, on these models it is vital to carry around a thumb drive with the firmwares on it. In the last year, I’ve seen more and more odd problems on these newer models and most of the time updating the firmware solves the problem.
