    Working part-time, I bring in more than $27,000 USD per month. I listened to a variety of people explain to me how much money they would reasonably expect to make online, so it’s still difficult to determine. It did become all genuine, and it completely altered my life. Everyone should now just try this line of work.

If your HP CP4525 printer is hanging on every restart with the error code 49.FF03 device failure, it may indicate a problem with the printer's hardware or firmware. Here are some steps you can try to fix the problem:

  1. Restart the printer: Try restarting the printer to see if the issue is resolved. To restart the printer, turn it off and unplug it from the power outlet. Wait a few minutes, then plug it back in and turn it on.
  2. Check for firmware updates: Make sure that the printer has the latest firmware installed. You can check for updates on the HP website or through the printer's web-based interface.
  3. Check for hardware issues: Check the printer for any visible damage or issues with the hardware. Make sure all the cables and connections are secure and not damaged.
  4. Reset the printer: If the above steps do not help, you may need to try resetting the printer. To reset the printer, turn it off and unplug it from the power outlet. Then hold down the power button for 30 seconds and release it. Wait a few minutes, then plug the printer back in and turn it on.
If none of these steps help, you may need to contact HP or a technical support team for further assistance. It is also a good idea to check the documentation or manual that came with the printer for any troubleshoot

Installation of hp colour laserjet cp4525 issue via usb

Your printer should have been packaged with a USB cable regardless of whether it is a wireless or wired printer. Plug the cable into your printer and your computer's USB port. The direct linking should trigger your computer to recognize the printer and start up the software needed to complete the installation.

you might need to update the fuser assembly. Please ensure that there are no other issues (ie paper jam or low toner level) before restarting your printer. Otherwise, please ensure that your printer isn't overheating. If so, turn it off for 30 minutes before using again.

Thank you.

My HP LaserJet CP4025 has a device failure screen and error code 49.FF03 what does this mean? It will not do anything.

The first course of action with any 49 error is to get the newest firmware installed, if the machine will come to a ready state. Unplug any USB or network cables and power cycle the printer. If it comes to ready, check any computers configured to print to ensure that no stale print jobs are stored in any print queues. (this is an important step, double check that all workstations are cleared). Once you are sure you have all queues cleared, plug the network or USB cable back in and see if printer stays are ready. If it does, go to and download the current easy firmware installation file for the 4025 and follow the instructions to update the firmware. If the machine will not come to ready even with network/usb cables disconnected then you may have a bad formatter or faulty memory on the formatter.

How to fix hp color laserjet cp4525 error code 49.4B03

Disconnect all usb and network cables and cycle the power. If the printer comes to ready then chances are you do not have a "hardware issue". Most common cause of 49 errors is out of date firmware. If you search the tips I have posted there is a detailed one on how to upgrade firmware.

My HP CP4525 has message :Mem Test Failure - Replace FMTR. Can you tell me what this is?

Replace the Formatter Board

HP4550 - 49.00FF service error

Turn off the RAM disk on the printer.

Follow these steps:

Troubleshooting steps

Verify that the formatter light is blinking or steady. If the formatter is blinking, it is functioning properly and probably does not need to be replaced. If the formatter light is not blinking, proceed to Step 2.
Turn off the printer and unplug the power cord.
Remove the HP Jetdirect card, third-party device, hard disk, parallel cable, or IFR cable from the formatter if one is installed.
If the error continues with accessories removed from the formatter, perform a cold reset on the printer. Ensure the HP Jetdirect card is not in the printer during a cold reset or the card settings will be changed back to default settings. To perform a cold reset, do the following:
Turn on the printer.
Watch the control panel.
When the memory starts counting, press and hold the green (Select ) button.
Continue holding the green check button until the Ready, Data, and Attention lights flash once, and then stay on steady.
Release the check button when the Ready, Data, and Attention light are on steady.
The control panel will display SELECT LANGUAGE .
Press (Down Arrow ) button once. The control panel will display COLD RESET
Press (Select ). The printer will perform a cold reset and then continue its power-on sequence.
If the printer comes up to ready, print a Configuration page. If a 49 error occurs from printing internal pages, continue on to the next step.
Turn the printer off and unplug the power cord.
Remove the eight screws around the formatter.
Remove the formatter. See Figure 1.
Reseat the firmware and memory modules on the formatter. Check for any DIMMs that are non-HP and remove them. Non-HP DIMMs are not supported by HP and may cause this error. Replace with HP DIMMs, if necessary.
Reseat the daughter (interconnect) board. The daughter board is connected to the formatter behind EIO slot #1. To release the daughter board, push in the black retaining tab underneath the formatter then lift up the one side of the daughter board.
Reseat the daughter board.

Install the formatter.
Turn the printer on again.
If it comes up to READY , print a configuration page. If a 49 error does not appear from printing internal pages, or at power up, continue to the next step.

Install the HP Jetdirect card and hard disk before installing the formatter. Verify that each device is properly seated.
Test any EIO devices, by turning off the printer, installing each device separately, and printing a Configuration page. Repeat for each EIO device.
If the 49 error occurs with any EIO device installed, replace that EIO device.

Keeps shutting down.

To resolve the issue, Please perform the following steps:

Step 1: BIOS Reset

To reset the BIOS defaults, follow these steps:

1. Restart the computer and press F2 (F10 in some Notebooks) as soon as the HP logo appears.
2. Go to Exit menu and select Load BIOS defaults or press F9.
3. Go to Exit menu and select Save changes and Exit or press F10.

This will reset the BIOS defaults. Now, when the Notebook restarts, press F8 repeatedly until the start up menu appears. Select the Safe Mode and press Enter Key to enter in Safe Mode and then perform the step 2.

Step 2 : Disable the "Automatically Restart" under System Failure:

1. Click Start, right-click the My Computer icon, then Properties.
2. Click the Advanced tab, then Settings in the Startup & Recovery section.
3. Remove the check mark next to Automatically Restart under System Failure.
4. Click OK to close the Startup and Recovery window, then click OK to close the System Properties window.
5. Restart the computer.

Step3: Reinstall Power management

To reinstall Power Management in Windows XP, follow these steps:

1. Click Start, select Control Panel, and then choose Performance and Maintenance.
2. Click the System icon to open the System properties window.
3. Select the Hardware tab and click Device Manager.
4. Click the plus (+) sign next to System Devices.
5. Right-click the ACPI Fixed Features button and select Uninstall.
6. Restart the system.

On restarting the system, Windows will automatically detect and install Power Management on the computer.
