Please reseat the memory DIMM of the printer
Then perform cold reset
NOTE: The Jetdirect LAN (such as the IP address of the printer) settings will be reset to defaults by this operation. Record LAN settings before resetting the printer. Reconfigure LAN settings after the reset if you are using a LAN connection). To avoid resetting the LAN settings disable the embedded Jetdirect before performing a Cold Reset by choosing the Disable LAN option from the choices available when you get to step 5 below. Note that after choosing to disable the LAN it is necessary to reboot the printer and then choose to perform the Cold Reset . During the power up sequence only one operation can be performed at a time. In this case, first disable the LAN, then reboot the printer and perform the Cold Reset followed by another reboot to reenable the LAN.
To perform a cold reset:

  1. Turn the printer power off.
  2. Power on the printer and watch for the memory count to begin.
  3. Hold down the SELECT (Checkmark) button, when you see the memory count begin.
  4. Continue holding down the SELECT (Checkmark) button until all three printer control-panel lights flash once and then remain on. This might take up to 10 seconds.
  5. After the message SELECT LANGUAGE appears on the display, press the UP ARROW button or the DOWN ARROW button until COLD RESET appears on the display
  6. Press the SELECT (Checkmark) button. The printer performs a cold reset and then continues its power-on sequence.
  7. Check all I/O settings and reset any user-set printer configuration values.


Please upgrade the firmware of the printer:
1. Download the firmware file from the following website and extract it.
http://h20000.www2.hp.com/bizsupport/TechSupport/SoftwareDescription.jsp?lang=en&cc=us&prodTypeId=18972&prodSeriesId=412144&prodNameId=412158&swEnvOID=54&swLang=8&mode=2&taskId=135&swItem=lj-25065-13
Expecting that the printer is connected over the network:
=============================================
Remote firmware update by using FTP through a browser
Complete the following steps to update the product firmware by using file transfer protocol (FTP) through a browser.
NOTE: The following instructions can be used on Windows or Macintosh operating systems.
Take note of the TCP/IP address on the EIO-Jetdirect page. The EIO-Jetdirect page is the second page of the configuration page printout.
Open a browser window.
In the address line of the browser, type ftp://<IPADDRESS>, where <IPADDRESS> is the TCP/IP address of the product. For example, if the TCP/IP address is 192.168.0.90, type FTP://192.168.0.90.
Locate the downloaded .RFU file for the product.
Drag and drop the .RFU file onto the PORT1 icon in the browser window.
NOTE: The product automatically restarts the firmware to activate the update. At the end of the update process, the Ready message appears on the control panel.

The following describes how to upgrade firmware in the LaserJet 2400, P3005 and 5200 Series Printers using a USB connection only.
To send the firmware upgrade via USB, you will need to know the name of the computer the printer is connected to, and the printer will need to be shared.
=============================================
=============================================
To find out the name of your computer:
Click the Start button, Programs, Accessories, System Tools, then choose System Information.
You will find your computer’s name in the right window-pane next to System Name.
Write down this name as it will be needed later.
To share the connected printer:
Click the Start button, Settings , then choose Printers ("Printers and Faxes" on WinXP).
Right click on the printer you need to send the upgrade to and then choose Sharing.
On WinXP, if you encounter the following link "If you understand the security risks but want to share printers without running the wizard, click here.", click the link.
Select "Just enable printer sharing" and click OK .
Select Shared As: ("Share this printer" on WinXP) and type a name for the share.
Click Apply and write down the share name as it will be needed later.
To send the firmware upgrade using a USB connection:
Go to a DOS Command Prompt and locate the directory where you saved the firmware file. (To open a Command Prompt inWindows 2000 or XP, go to the Start button, then choose run, then type CMD and hit Enter, in Windows 98 or ME, go to the Start button, Programs, Accessories, then choose MSDOS Prompt). This will bring up a small black screen as displayed below:
If connected to a USB port, Type: copy /b filename \computer nameshare name (for example, copy /b ozfw.rfu \computer1printer).
Press ENTER .
The control panel displays receiving upgrade followed by performing upgrade . The download may take several minutes.
The control panel displays processing job .
The download is complete when the printer reboots and "READY" message is displayed on the control panel.

WHERE'S THE FUSER ROLLER AND WHERE DO YOU PURCHASE FUSER OIL ON A HP LASER JET 4250 N PRINTER?


The 4250 uses an "assembly" that does not use fuser oil. The fuser is housed in the rear of the printer. It applies heat and pressure to the paper as it exits, melting the toner into the fibers of the paper. Some fusers are remanufactured. If done properly, with the proper amount of fuser sleeve grease, these fusers can last as long as the original equipment fuser.
If not properly trained, fusers should not be disassembled and rebuilt.

Blank display


If the printer control panel is blank when you turn on the printer, check the following items.
1 Make sure that the printer is plugged into an active electrical outlet receptacle that delivers the
correct voltage.
2 Make sure that the on/off switch is in the on position.
3 Make sure that the fan runs briefly, which indicates that the power supply is operational.
4 Make sure that the control-panel display wire-harness is connected. See the hint in the
procedure for Top cover.
5 Remove any HP Jetdirect or other EIO cards, and then try to turn the printer on again
