Uninstall and reinstall with the latest software from http://support.hp.com for your OS. That should repair any connections that have broken.

Check your toner cartridge first. There is more than one cause for this problem. It could also be your transfer roller that needs to be replaced. Or it could be the scanner that has gone out. Are you getting an error code?

When you replace the fuser unit it will reset automatically

cold= hard reset, unplug the machine-- wait 1 minute-- with power off hold down on power button for 1 minute-- plug back in and power up

please check the papper jam or sncer hang

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 HP.com 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.

Hi I have taken this directly from the User Guide "57 Fan error Turn off then on Description - The product has experienced a problem with its internal fan. Recommended action Turn the product power off, wait at least 30 seconds, and then turn the product power on and wait for it to initialize. If you are using a surge protector, remove it. Plug the product directly into the wall socket. Turn the product power on. If the message persists, contact HP support." For future reference this manual can be found here: http://h20565.www2.hp.com/hpsc/doc/public/display?docId=emr_na-c02966093 and being in pdf format can be saved to the computer. Hope this is helpful, if so would you please register that with Fixya Cheers

59 error indicates a main motor failure. This if often caused by a jammed cartridge, so trying a new toner cartridge would be your first step to trouble shoot this.

see HP LaserJet Pro Printers Memory is Low message displayed on the control... HP LaserJet Pro Printers - 'Memory is Low' message displayed on the control panel HP LaserJet Pro - Troubleshoot 20.xx (memory failure) and 21.xx (print failure) error messages (ID: emr_na-c05049204) HP Customer Support page and ensure the printer is running the latest available firmware. Print a Configuration Report from the control panel of the printer to check the installed firmware version.

If the printer supports expandable memory, you can install additional memory in the form of a DIMM. Check the printer's User Guide to see if it supports additional memory.

Break complex print jobs into smaller jobs that contain fewer pages.

If the printer is an MFP, delete stored faxes to increase available memory. Go to this document for instructions: HP LaserJet Pro MFP - Delete faxes from memory (ID: emr_na-c03264743)

Power cycle the printer to delete stored fonts or macros. It is possible to download fonts or macros in a way that power cycling the printer will not delete them; see Appendix A - Memory Allocation.

Changing some software and/or print driver settings might result in a less complex print job.

Use a different print driver. For example, a PostScript print driver will typically result in a more complex print file. If possible, try sending the file with a PCL6 or UPD printer driver.

Adobe PDF files can sometimes be very complex. Go to this document if printing PDF files is slow or resulting in memory out messages: HP LaserJet - Print job is slow or hangs in the print queue when printing Adobe PDF files (ID: emr_na-c04071740)

If the printer is connected via a network, try sending the file connected by USB cable only. This will eliminate possible network issues that are taking printer memory.

Appendix A Memory Allocation Utilities or jobs that you download to the product sometimes include resources (for example, fonts, macros, or patterns). Resources that are internally marked as permanent remain in the product memory until you turn the product off. Use the following guidelines if you use the page description language (PDL) ability to mark resources as permanent. For technical details, see an appropriate PDL reference for PCL or PS.

• Mark resources as permanent only when it is absolutely necessary that they remain in memory while the product is turned on.
• Send permanent resources to the product only at the beginning of a print job and not while the product is printing.

NOTE: Overusing permanent resources or downloading them while the product is printing might affect product performance or the ability to print complex pages.

Need the model number

-You can hook up and look up on HP online to identify the ip address. Good Luck Mai

Seems the wifi controller in the printer is fried. This worked for me.
Power on
Press Home button repeatedly while the unit is powering up.
When the menu appears hit these items quickly
1. Wireless Menu Icon (wifi icon)
2. Wireless Menu Button
3. Turn Wireless On/Off Button
4. Off Button

You have about 2.5 seconds to do this so it likely will take a few tries. When you have successfully disabled the wifi, the printer menues will work and the initializing sequence will finally complete.

You will have to hardwire the printer to an ethernet network or use some sort of wifi to ethernet adapter if you want to print over the network but the printer still works.
