LaserJet Pro 400 M401dn - 79 SERVICE ERROR

We have only had this printer less than a year and I am getting a 79 SERVICE ERROR. I have power cycled, unplugged and all the normal tries... no go. It will print the menu map but will not accept a print job from a user. I try to get to the printer page on HP.com but it errors out so I cannot get to any of the support docs for the model. Anyone out there have a suggestion?

I ran into this same problem with the LaserJet M401dn. I noticed this issue occured when the printer was hooked up to the PC via USB. I followed HPs steps on trying to fix this problem and needless to say, their steps weren't worth a hill of beans. The printer is working now now via these steps that I'm going to list. 1) Restart the printer with only the power cord being attached. If you're STILL getting the 79 error service, then it is most likely a firmware issue. Luckily for me it wasn't. The printer started right up as it should.2) If your printer starts right up, attach an Ethernet cable from the printer to your router/switch/DSL or cable modem.3) Select the Network icon on your printer screen and check to see if your printer has authenticated to the network and lists an IP address. If you're on a home network the IP address will show something like 192.168.x.xx. 4) Once connected to the network you'll run a firmware update. Click on your Settings icon, select LaserJet Update, Check for Updates Now. Continue by selecting the update and download and install. After the firmware installs, at this point you might be able to get the printer to work by hooking the USB cable back up to the printer. I on the other hand did a couple other steps before hooking the printer back up. 5) I installed all of the Windows Updates (critical), updated Java6) Uninstalled the HP printer software for the M401dn and restarted the PC7) THIS STEP IS NOT FOR THOSE THAT AREN'T FAMILIAR WITH EDITING THE REGISTRY. If you have no knowledge of how to edit your registry, then PLEASE DO NOT ATTEMPT this. Have someone with knowledge do this step. I, nor HP can be held responsible for any mistakes that you make with this step. DO AT YOUR OWN RISK. In the registry I searched for Packard and deleted all Keys or entries that had M401 listed. DO NOT DELETE THE KEY IF IT DOESN'T LIST M401, as there are Hewlett-Packard printer drivers that are built into the operating system and they do show up in the registry.I ran through the registry twice searching for any sign of the printer driver being installed. Restart the computer again.8) Reinstall the HP LaserJet Pro 400 M401 Printer Series PCL6 Print Driver that is relevant to your PC. (Sorry, I don't know how to deal with Macs.) DON'T download the Full Software and Drivers or the one WITHOUT the installer. Don't use the disc to install the drivers either. Just download the most recent version of the software from HPs website. Install the software and attach the printer when asked to do so. Hopefully you're golden at this point just like I was! If for some reason this doesn't work for you, I would format your hard drive and reinstall Windows and all of your software. Apparently there is something within the registry or on your computer that is keeping the printer from working. I hope this helps you all out!

HP LaserJet Pro 400 M401dn

Good time of day. I have a problem with the printer. It should be the latest firmware of the printer. The printer goes into standby mode. Send a print job, the printer comes out of sleep mode. And for a long time thinking and prints. About page per minute print. Turn off then turn it on and it starts to work normally. Help me.

Laserjet Pro 400 MFP M425DN Can not connect to HP Web Services

I have a Laserjet Pro 400 MFP M425DN printer on a network running windows 7 and we Can not connect to HP Web Services. When we use the display on the menu it comes back with error "Internal Processing error, try again or check firmware update" We installed the new firmware but still get the same message. IF type in our printers IP address into our browser we get the info on our printer but if we go to the HP web services tap and click enable it trys but come back with a "connection error"
Any ideas?
Thanks
Paul

I just updated my Firmware on this printer today to the latest version dated May 3 2013 and Web Services
worked. Had the same type of problem you had for months and had worked with HP but could never get
Web Services to work at my location with my Modem/Router.
Had tried at other locations and it would work with the old Firmware. But for some reason it did not at my
location with the Modem/Router I was using.
Again the latest Firmware fixed it. I tried all the other solutions that I had found on the internet and non of them worked.

I would try pulling up the embedded web server (EWS) by entering the IP address for the printer in to a browser and set a static IP address & DNS.
The information for the default gateway, subnet mask and that IP address can be accessed from the Setup menu on the front panel, go to Setup>> Reports>> Network summary and that will print it off.
Once you have entered the IP in to a Browser and have the EWS pulled up, navigate to the tab at the top labeled “Networking”. Then click on IPv4 in the left column; that will bring up the Address configuration page. Set the radio button to manual and fill out the IP address, Default gateway and Subnet mask with the information from the report. Do not worry about filling out the portion titled WINS server, that can be left alone.
You will then want to fill out the DNS portion of the page, The Preferred should be set to 8.8.8.8 and the alternative/secondary should be set to 8.8.4.4. Then click “apply”
Power cycle the printer. Turn it off, wait 30 seconds and then turn it back on. Once it is completely up and running reattempt to connect to web services.

Hp laserjet pro 400 color MFP model m475dw repair manual

While trying to copy some documents, display shows the following errors:
1.- Service error 49. I'd review on a downloaded owner manual what to do and no more messages. After I restarted the printer shows the following error.
2.- Service error 79. I'd followed the the owners manual once again and the problem was solved, then I discovered that the upper paper tray send the message to remove clogged paper, I'd removed the paper and then when I try to make a copy the printer showed me on display the scanner number 6 error.
I want to check the upper tray assy to avoid broken parts cause the tray stared to do a rattling sound...

2nd fax won't work at Laserjet Pro 400 MFP M425DN

I have recently bought the HP Laserjet Pro 400 MFP M425DN, which is working almost fine.
The problem is when i do want to send a fax, it will send it, but after that the second fax won't be able to send. I just get the message 'communication error'. Also, the beep-sound the machine makes when you normally push a button on the touchscreen, becomes REALLY soft instead of a hard beep.
The only way to solve this problem is to open the papertray and close it again. This is annoying due the fact that i have to send more than one fax a at time.
PLEASE help

Hello try to send the first fax then push home button and then send second fax

Grinding noise when my HP LaserJet Pro 400 color MFP M475 calibrates

When my HP LaserJet Pro 400 color MFP M475 recalibrates, I get a grinding or gear slipping noise. Any idea how to fix it or what to look for?
This question was solved.
View Solution.

Noise issues are difficult to troubleshoot remotely and they could easily misguide even when we are close to the device.
Please do confirm if the noise is a grinding noise or squeky/humming noise.
As you have mentioned that it happens only while calibrating, hence I would suggest you to re-check & validate your toner cartridges. One of the toner cartrdige may be defective and causing this issue.
If not the toner cartridge then it would be one of the printer hardware component which is in question, hence an HP tech. might need to perform physical inspection of the device and the error condition.

Squeaking when my HP LaserJet Pro 400 color MFP M475 feeds from Tray 1

There is a low pitched squeaking when my HP LaserJet Pro 400 color MFP M475 feeds from Tray 1. We use this tray for printing individual envelopes. Is there a part that I should replace or clean? Trays 1 & 3 feed with no noise.

Driver Windows XP for HP Laserjet Pro 400 MFP M425dn

I have a problem installing the driver HP Laserjet Pro 400 MFP M425dn for Windows XP Profesional SP 3.
At the beginning of the installation appears error message "HP CSI Shell - found an error" but the installation continues, but after a few seconds the following message appears "HP installer - found error". The installation continues, and soon appears a message that says "Click the" Install "to install the driver," I click the button "install" and appears the message "encountered a fatal error that prevents the use of the product".
What's the problem? every time one and the same set of error in the printer to the operating system Windows XP.
With other operating systems is no problem

Hey @AlchemistYA ,
I suspect your question would be better answered in the HP Enterprise Business Community, as your HP Printer is a commercial model.
My technical expertise is with consumer products and software, I am sure the commercial folks would be happy to help if you re-post your question for them to answer. The HP Enterprise Business Community is an HP Forum designed for the Commercial and Enterprise customers to help one another. I am sure you will find some HP folks there to help too.
Click here to view the Printing and Digital Imaging. When the page opens you will see the option to 'Log in' or 'Register Now' on the right. The commercial forums are separate from the consumer boards, thus you will need to register if you don't already have a commercial account.
You may find the HP LaserJet Pro 400 MFP M425 page helpful while you wait for somebody in the commercial Forum to respond to your inquiry.
Best of luck.

Toner won't come out LaserJet Pro 400 MFP M425

toner won't come out LaserJet Pro 400 MFP M425. It's stuck inside.

I am sure it is stuck on the right side. Odds are also that it is an aftermarket toner and not an hp original. That said it will not be easy to remove. You will have to do a google search for the service manual. The right side cover needs to come off and it is not easy since the back, top and control panel need to come off. Once you have the right side cover off you will see a big while gear behind the metal plate that holds the gear assembly to the right side. You need to turn that gear by hand a little and it should free up the toner to come out. When you remove the toner you will see a sort of bell housing metal piece that hangs on the right side of the toner. That assembly fits down the right side and locks into the mech that turns the toner drum. If that piece has defect it gets stuck. Good Luck. First thing I would try is to unplug the printer, then plug the printer back in and let it come to ready and open the door to see if the toner now comes out. Sometimes turning the printer off and then back on will turn that gear by itself and free that piece.

HELP! My HP LaserJet Pro 400 color MFP M475dn printer will NOT print!!!!

HP LaserJet Pro 400 color MFP M475dn- CE863A
Printer is on a network and can connect to multiple computers that include: Mac OS X, Windows 7, and Windows XP.
When I try to print from my iMac, the printer queue says "The printer is not connected". When we try to print from the Windows computers, it just sits there in the queue and doesn't print. When I go over to the printer itself and try to print either a demo page or a supplies page directly from it, it says on the screen that is printed it but nothing happens. It doesn't hum or anything! The port where the network cable is connected is lit green which HP says that means that the network cable is connected. We have had this printer for a year now and something like this has never happened.
I haven't switched any software or anything before this happened. It was working fine on Saturday when we were using it, but when we came into work today, it just decided it would stop printing!
I am stumped! I tried 'pinging' the printer's IP address from my iMac and it pings just fine. Does anyone have any tips?
(I tried doing the obvious too- like turning the printer on and off and shutting the computers down- and nothing!)
This question was solved.
View Solution.

Okay, so I'm feeling slightly stupid right now. I decided I would shut the printer down for about an hour to see if that was it and what do you know- it was! I had shut it off a few times before but I guess it just wasn't long enough. What a pain!
Thank you to anyone who took the time to read this! Sorry to waste anyone's time!!

HP LaserJet Pro 400 color Printer M451dn won't print

My HP LaserJet Pro 400 color Printer M451dn stopped printing after a short usage of non hp toner. How do I get this printer to accept these toner cartridge ? My 3600dn never has a problem

If you are using non-HP toner cartridges, then I would say that the onus is on the supplier of these to resolve the problem.
Or to accept that these cartridges aren't quite as compatible as they've no doubt been advertised to be.
