HP OFFICEJET 4630 in single cartridge mode

I just installed a new black and a color HP print cartridge in my Officejet 4630 All in one printer. Although pages are printing both black and color, when I go to copy mode it has two options to Copy in black or Copy in color. I have removed and replaced the cartridges three times and aligned each time, but the screen still shows the two options.
Does anyone know how to correct this?
Thanking you in advance
This question was solved.

Hi,
Could you please clarify your intention?
Whie both the Black and the Tri-Color are installed, the Copy menu should liste both Copy Color to perform a color copy or Copy black to copy a document as black and white, that is an expected behavior of the printer.
Please clarify if I may misunderstood yoru intention, do you expect any other options to show?

Single Cartridge Mode Failing

This printer is capable of single cartridge mode and it has worked this way for years. However, when I replaced the black cartridge (which I have done many times), this time it will no longer print, complaining that the tri-color cartridge is missing. But it has always been missing, because I only ever print black/white.
I know it is recognizing the new black cartridge because if I remove it, then the same message displays and says the tri-color AND black ink cartridges are missing. So, it feels like some kind of setting where now the printer demands that both cartridges are present. What gives?
The exact message when I do a "print test page" is:
"Ink Cartridges Missing. ---Tri Color. Cartridges listed above seem to be missing, are not detected, or are incorrectly installed. If ink cartridges have been installed, check that the plastic tape covering the ink nozzles has been removed. "
Thanks,
Kyle

I bought a new cartridge and everything worked perfectly immediately. So, I guess a bad cartridge just has some misleading messages around it, but we're up and running now. Thanks!

HP Officejet 4630 e-All-in-One Printer Black Ink not Working

My HP Officejet 4630 e-All-in-One does not print black ink but the color ink is working perfectly fine even though the ink status shows that there is black ink left. After I've changed a new black ink cartridge, it will start to work again but after one day it stop printing black ink again. I've only printed a page the previous day and the ink status shows that there's black ink left in it (close to full). I've tried the methods stated here (http://h10025.www1.hp.com/ewfrf/wc/document?docname=c03882718&cc=sg&dlc=en&lc=en&product=5305051) but the black ink still doesn't work. So how can I solve this problem??

Hello @3oshua,
Welcome to the HP Support Forums! I see you are running into some print quality issues on your HP Officejet 4630, you are unable to print in black ink, even after replacing the cartridges.
I see you have exhausted the steps listed here: Printer Does Not Print Black Ink or Color Ink, or Prints Blank Pages, with no success.
Please note: There are three printhead cleaning stages. Complete all three stages if necessary. If the printhead is badly clogged, it might require another cleaning cycle. If so, wait 30 minutes after the last (third) cleaning stage to start the first stage of the cleaning process over again.
If you are still unable to print in black ink, I suspect the issue may be the printer and not the cartridge. I highly recommend you call our technical support at 800-474-6836, to see what options they have available for you.

Officejet 4630: Error code 0XB00A7A4E and it's all it does.

Hello, my Officejet 4630 had some problems, yesterday it asked me if I wish to install ne w firmware and I thought this would solve the problems, so I clicked ok.Now it does not do anything anymore.It displays error code 0XB00A7A4E, and beeps all the time. I took out the USB, the power, waited... same thing.The Online forum says that one should open it and take out the cartridges, but when I open it, the cartridges do not come to the middle, to the "removable" area. So it is completely stuck.Any help? Thank you!

Hello , Welcome to the HP Community!I hope you have a pleasant experience here. I'd like to help you with the 0XB00A7A4E error that you are getting on your HP Officejet 4630 e-All-in-One printer. Errors such as the one you are experiencing can either be caused by a firmware issue, or a jammed carriage. It can be difficult to tell which. One of the most common fixes for a firmware error is to plug the printer directly into a wall outlet. The printer has a power moderator built in, so if it is plugged into a surge protector or battery backup, it often causes a power fluctuation. This can result in firmware errors similar to what you are experiencing. I'd recommend trying this first. If that doesn't immediately resolve the issue, I'll get you to check the cartridge carriage inside the printer. Is it locked in position? Are you able to move it at all? If you can move it, I recommend uninstalling and re-installing the cartridges. If not, I'd recommend contacting our HP Phone Support for further assistance:Step 1. Open link: www.hp.com/contacthp/
Step 2. Enter Product number or select to auto detect
Step 3. Scroll down to "Still need help? Complete the form to select your

HP Officejet 4630 unable to update

Despite following all of the instructions for both the download, install& update and the forum posts (including unplugging the network, power, and removing all of the ink cartridges from my HP Officejet 4630) I'm unable to get the latest update to install, and my printing is totally hosed. What are my remedies? This is infuriating; all of the printing is messed up and I can't use this printer. It's almost as if as soon as the warranty expires the item becomes useless. HELP!!! Thanks in advance....

Hi @deb2924 , and welcome to the HP Forums!
I see you're having issues updating. I would like to assist.
You mentioned that the printer is hosed. What exactly is wrong with the printer?
What happens when you try to make a copy?
Do you have any errors displaying?
Please let me know. Thanks for posting!

Brand new officejet 4630 with black ink problem and ok button doesnt work

Hi! I bought a new printer today, officejet 4630 and it included toner cartridges in the box. Iset it up like the sheet in the box said. After I had filled in date etc, I put in the ink ( and yes, remembered to check that it was compatible and take of the tape) Then this message showed in the display and still does: "Ink cartridge(s) problem. The following ink cartridges must be replaced" and a black dot. The cartridges were brand new and came in the same box as the printer. I have tried a reset ( taking out the cord for power supply, wait 60 sec etc) I also saw in Hp support you were to press "ok" to get rid of the message before restart. I can't press ok. It just beeps. No matter what button I press. Suggestions? Of course I can try with a new cartridge, but to paying $20 for a new cartridge when it was included in the box and should work is not ok.

Hi , Welcome to the HP Forums! I understand that you ar getting the error, "Ink cartridge(s) problem. The following ink cartridges must be replaced" with your black ink cartridge on your HP Officejet 4630 printer. I am happy to look into this cartridge error for you! Please, try the steps within this guide, A 'Cartridge Missing,' 'Cartridge Problem,' or 'Incompatible Ink Cartridges' Error Message Displays for HP Officejet 4630 and HP Deskjet Ink Advantage 4640 e-All-in-One Printer Series. If this guide does not resolve your issue, please contact HP, phone support for further assistance, as the ink cartridge(s) are under warranty.

HP Officejet 4630 e-All-in-One Series

Hello,
I have just bought a Mac book Pro and and HP Officejet 4630 printer. I started setting up my printer and since I am in college and using my school's wireless connect. The only way to locate my printer is by changing my wireless connection to the printer name but then I can still not print, and it does not always show up on the settings. I would really like to be able to use my printer.
Thanks,

Hi @cn70
In a school environment, I suggest using either a USB connect, or the Wireless Direct. If you use the Wireless Direct, I recommend turning it on 'with security'. use the link below to learn more about Wireless Direct.
What is HP wireless direct? How to connect to HP wireless direct, and How to use the HP wireless dir...
If you continue to experience issues with either of these connection types, let me know and I will happily do all I can to help. Thanks.

Data back up from Single User Mode

Hello,
I have a problem with my 700 MHz iBook, dual USB, with OS X 10.3.9.
Unfortunately the OS doesn't start up because of "overlapped extent allocation" problem...
I would like to re-install the complete OS but before doing it, I would like to back up some directories.
Is it possible to save some data, by connecting an Ipod or some sort of external peripheral, from the Single User mode?
If yes, how can I do it?
Thank you in advance from your kind support.

Before giving up the ghost check out these:
http://docs.info.apple.com/article.html?artnum=25770.
Manually fix Overlapped Extent Allocation Errors without Disk Warrior
Overlapped overlapped extent allocation errors can be the bane of any Mac user's existence. Often, these errors go unnoticed until the problem becomes visible: your Mac might refuse to boot, crash unexpected, or worse, critical data might disappear from the Finder. Disk Utility can detect, but not fix overlapped extent allocation errors, and certain third-party utilities, such as Alsoft Diskwarrior, can fix them, but generally without reporting the consequences.
Overlapped extent allocation error occur when the file system thinks that two files are occupying the same area on the hard disk, hence overlapping on the same "inode," which is the structure which holds the location of the data blocks the file occupies, and also file permissions and flags.
Clearing the "overlapped" or "overallocated" extent allocation essentially means that you'll have to lose some data, because the only way to remove the overlap is to delete the file that's occupying the inode. So, if you suspect, or find out, that the guilty file is a critical system file that resides in one of the hidden system directories such as /etc /var /usr/ or visible system directories such as /System or /Library, and you don't want to reinstall the whole OS (which might not fix the overlapped extent allocation anyway), it's good to have another disk available to copy the files back to your original disk if necessary: a second bootable hard drive or a firewire drive connected to your Mac when you remove the misbehaving file. Just make sure that when you copy the file back to your boot disk that the permissions are correct, so it's best to use the "ditto" command, so that all sticky bits, flags, and permissions are preserved.
In case you didn't know, you don't have to boot from an install CD in order to check for overlapped extent allocations. All you need to do is restart your Mac, while holding down command + S to boot in "single-user mode."
At the command prompt that appears, type:
$ fsck -fy
If you have an overlapped extent allocation, you'll see:
"Overlapped Extent Allocation" (File 123456d)
No matter how many times you run fsck -fy, you'll never be rid of the error.
So, simply issue the following command:
find / -inum 123456 -print
Note the "d" was dropped, or any extra letter that appears after the inode number.
The find will return a file name that matches with the inode number, and the path to that file. If you remove the file then the fsck will not return this error next time you run it.
However, before you can delete the file(s) in single-user mode, you'll need to mount the file system. Type:
$ mount -uw /
When done, issue the "sync" command, and that will flush the write cache so that all pending writes are written from memory to the disk. Also, since most OS X 10.3 Macs use the HFS+ Journaled file system, it might be a good idea to disable the journal before booting into single-user mode by typing:
$ sudo diskutil disableJournal /
then re-enable it when done fixing the overlapped extents and rebooting normally:
$ sudo diskutil enableJournal /

If you own Disk Warrior then it should be able to repair a drive with overlapped extents.
There are two backup utilities included in Unix - psync and rsync. You will find them in the /usr/bin/ directory. For documentation simply enter: man psync or man rsync. In order to write data while in single-user mode you need to issue the command: /sbin/mount/ -uw / (Note: there is a "space" between the "uw" and the "/".) To mount an external drive you will need to provide the mountpoint for it in place of the "/", e.g., "/Volumes/volname") without the quotes.

How do i repair my hard drive in single user mode when disk is full?

Hi there Apple Community!
I have an old Macbook Pro 17" with an upgraded 500GB harddrive and 4GB memory. I'm running Mac OSX Lion.
Was hoping you could help me out. THis is the situation:
Long story short I spilt wine on my macbook and the screen went a bit blobby. Switched it off for a few days, removed the battery etc. etc. Opened it up cleaned out as much of the wine as possible, but unfortunately some of it came in behind the LCD, so now the screen has a nice red stain. Obviously I'm not going to try to clean that out of the LCD.
My Macbook Pro still worked for a few days after that, but then my harddrive gave up. I booted in the Recovery HD menu, verified the drive and I got the error "Keys out of order - This disk needs to be repaired, click Repair Disk." I attempted to repair the disk but got the error "Keys out of order - Disk Full Error - The volume could not be repaired".
Unfortnately of this 500GB I only have about 7GB free on it, as I have a huge iPhoto and iTunes library. I did make a TIme Machine backup of my user directory, but not the system files. I don't really want to do a clean install because:
1) I'm paranoid that there's something I did not fully back up
2) I don't want to have to download the whole Mac OSX Lion again. I should have made a USB bootable backup when I had the chance. I don't have access to a broadband connection.
What I feel are my viable options, are as follows:
1) I did buy a replacement internal 500GB harddrive, so I can probably try to make an image of the hard drive to this new drive, but not sure how. I believe it's through the Disk Utility with the "New Image" option but not sure how to go from there.
2) Start up in Single User Mode and delete some unnecessary files and re-attempt to run the fschk -fy utility again (I tried this earlier and got the same Disk Full Error). - the problem with this is, I'm not familiar with the command line and have no clue how to delete files. I don't know my way around Unix.
3) I can also probably attempt to make a Ghost Image or Acronis Image of the failed drive to this new drive, but not sure if Norton Ghost or Acronis True Image will be able to read this HFS drive - I believe it's possible as it's a simple hard drive clone.
If you can guide me in the best option - probably there is a better solution than my proposed ones above, I appreciate any feedback and comments you might have!

hi Baltwo,
So I ended up copying my user folder to another harddrive. I managed to download the whole osx lion again, reinstalled, and recovered my home folder using this discussion:

I've done an Apple Software Update but it didn't find an update for iPhoto.
One thing to note is, this library was originally created on iLife 08, upgraded to '09 and it stayed on that version. It hasn't een upgraded to iLife '11. It worked fine on my previous install of OSX Lion. How do I recover the library without upgrading to '11 ?

Kernel panic on MacPro in Single-User mode after memtest.

I've had about 7 kernel panics in about 7 days on a new MacPro. 2 gigs of RAM (Apple Installed). Fresh install of OSX (no user import). While going through the troubleshooting process I ran memtest in single user mode. Ran it all night no errors.
So in the morning I typed ctrl-c and then exit (i think)... it seemed to start the process of booting and I got another kernal panic. I've actually done this three times now.
I checked panic.log and all the error messages but 1 were the same. Including the ones I got in single-user mode (copied below).
Should I be able to gracefully exit out of single-user mode without a kernel panic?
Does this point to a RAM error even though memtest and AHD for that matter ran all night without finding anything?
I'm all set to try again (taking careful notes this time) to see if I can reproduce but I was hoping for some feedback first.
Thanks,
Craig

Welcome to Apple Discussions!
Yes, your memory or memory slot, or memory seating is bad or off. "Uncorrectable Fbd memory error detected. ferr = 20000000 , nerr == 00000000, fErrFat = 20000000 nErrFat == 00000000"
Clearly a memory related issue. It may also be that memtest doesn't know how to diagnose the new kind of memory and is reporting that back to the logs. Take it in to a service center to have all the boards replaced to make sure the issue isn't reproduceable with new memory. If it is, then I'd consider the slots on the logicboard a problem.

HP Officejet 4630 all-in-one printer Cancels Print in Middle of Job

Hi,
I recently bought an HP Officejet 4630 all-in-one printer, and it automatically cancels jobs in the middle of printing. The computer I am using is an HP Envy dv7 with 64-bit Windows 8, and I am printing over a wireless network connection. My computer receives an error that HP Officejet 4630 series couldn't complete print and the printer simply says canceling. I have tried all the steps in the troubleshooting sections, both for printing issues and network connections. I've uninstalled and reinstalled the software multiple times, I've established a manual IP, and everything else, but nothing seems to work. It also seems to have the issue when using HP ePrint. It happens in all sorts of programs and formats such as word, pdf, and html. Unfortunately, I did not receive a USB cord, so I can't see if that will fix the problem at all. Hopefully somebody can help me with this, otherwise it's obvious that there's a problem with the actual printer I got and I'm going to have to get something else.
Thanks
This question was solved.
View Solution.

This is how I fixed it:
Find out what the IP address is that your printer is using.
Then go to control panel and click on "View Devices and Printers".
Look for your printer an right click.
Click "Printer Properties" and a new screen will open.
Along the top you will see some tabs. Click the one that says "Ports"
Click "Add Port"
Highlight "Standard TCP/IP Port" by clicking on it, then click "New Port". A new screen will open.
Click "Next"
Type in the IP Address of your printer and click "Next"
Your computer should find your printer.
Click "Apply" and your printer should work correctly.

My PC can't stand the connection to HP Officejet 4630 all-in-one printer

Hi everybody,
I got a HP Officejet 4630 all-in-one printer, i manadge to connect it to the network. I select a static IP and i can reach the printer through the browser.
I can add the printer to the PC, the system can find it after few second od scannig, and than i can print a test page.
The problem is that if I reboot the PC or the printer, or both, i can' print no more.
The icon of the printer in the "device and printer panel" is blurred with the green thick, but i can still reach the print through the browser and i can print with the ePrint.
If I use the "problem solving" service of Windows, it can't find any problem. But i can't still print.
I don't know what to do, it seems a problem of the computer (i even tryed to turn off the firewall but it doesn't change anything)
Is there someone that could help me?
Thank you so much

Hi @poporni,
Welcome to the HP Forums!
I noticed that your HP Officejet 4630 keeps losing the wireless connection on Windows 7. I am happy to look into this connection issue for you!
Please, take a look through this guide, Printer Does Not Maintain Wireless Connection.
Tips for troubleshooting wireless connection issues
The following tips can help you troubleshoot and avoid wireless connectivity issues. You can try these tips separately or in combination to get a successful wireless signal.
Move the printer and the computer closer to the router, but no closer than 6 ft (1.8 m). Wireless signals can be weaker at greater distances between the printer and the router.
If you are experiencing an intermittent wireless connection, try restarting your router. Consult your router manufacturer, Internet service provider, or network administrator for instructions on how to restart the router.
Remove any metal objects between the printer, the computer, and the router. Objects such as refrigerators, microwaves, or metal bookcases can interfere with wireless transmission.
Move any device that emits radio signals, such as microwaves and cordless telephones, farther away from the printer. Such devices can interfere with wireless signals.
I would also recommend, our HP Wireless Printing Center - Troubleshooting Issues website.
Hope this information is helpful, and thank you for posting!

I changed my wheel group properties to no access at top disk level. I messed up, how can I change back in single user mode "command s" as I am now in Thailand and not able to access startup disks?

I messed up, I changed my "Wheel group" properties to No Access ( or something other than the default) at the top level of my startup disk "Macintosh HD".   Now my computer won't start up, I just get the spinning wheel of death.    I also am in Thailand right now, so I cannot go to a Genius at an apple store, nor do I have startup disks available.
So I was hoping there was a way to change back the properties of my disk (Volume) in single user mode (via Command +s) during startup, i.e. can I do a chmod command on the Macintosh HD listing under the Volume Directory.    Or where do i fix this?   Is it fixable without startup disks, etc...
THANKS FOR ANY HELP!!!!
If you could also please let me know you have an answer, I WOULD REALLY APPRECIATE IT!!!
thanks so much

Thomas,
Thanks for the info on command-R, didn't know about that!!!
Yes I changed the sharing "Wheel Group" permissions on my hard drive via Get Info.    But that's all I did.    And then most of the apps wouldn't respond with anything.    So not knowing I did something stupid, I decided to re-boot, and then nothing but the Wheel of Death at startup.
I was trying to limit access to my computer on this network, changed my public folder settings, and then I thought why not the whole hard drive, but at that time I had no idea what the "Wheel Group" was... so I shouldn't have touched it, BUT IT DID ...... argggggg....
I managed to go to an internet cafe & research the problem yesterday.    I used the command +s single mode to get in, and then did the necessary steps to mount the drive so I could make changes.   I basically did this:
Boot into single-user mode (boot while holding down CMD-S)
Follow the on-screen instructions to mount the file system as read-write (a fsck command followed by a mount command)
Type the following: "chmod o+r /" followed by "chmod o+x /"
Type "exit" to leave single user mode and complete the boot sequence.
I found it at this link http://forums.macrumors.com/showthread.php?t=416180
It worked... thank God!!!   Well so far so good.
I was going to try my own fix by chmod on the Hard drive listed under Volumes directory, but that doesn't seem to match the info under Get Info Window.    So I just used the fix above.    I probably should now go and do "Disk Utility - repair permissions", however I am a little gun shy right now, so I will probably wait until I am back in the States so I can go to an Apple store if it messes up.   Right now I'm following the "if it ain't broke, don't fix it" MOTTO...
So Thomas I just wanted to say THANKS for replying so quickly, and I really appreciate your help!!!
(yes I know I shouldn't have used my email addresses, but I WAS DESPERATE, but that's still no excuse)
Hopefully maybe this thread will help someone else out in the future....
Okay, thanks again!

Why can't I enter single user mode on my Mac Mini for an admin password reset?

Hi,
I recently created a new user account for my mac and deleted the old one, not realising that this was the only account with admin priveleges. As such, I no longer have access to administrator priveleges, and cannot grant them to my new user account.
I have tried to boot in single user mode and recovery mode but neither command results in any reaction on the part of my computer.
This thread follows on from a previous, unrelated disscussion:
BDAqua: If you hold alt key at bootup do you see a lock in the middle?
Yenots: No...what does this mean?
BDAqua: If it did, it would mean Firmware Password Protection was enabled, which prevents booting in other modes, so that's not the problem, are you using a wired Mac KB, or Windows KB?
Yenots: I'm using an 'Apple Keyboard with Numeric Keypad' [ http://store.apple.com/uk/product/MB110B/B/apple-keyboard-with-numeric-keypad-br itish ]
If you find me here BDAqua, hit me with your knowledge!
Any other contributions are welcome and, now we're under the right heading, will hopefully help other users who have encountered this problem.
Thanks, Cristo

Hi,
Thanks for the link to MacPilot, and the sexy screenshot. I found an archived version for 10.4 on the koingosw website. That solves getting into single user/safe mode. Though I'd be interested to see whether sudo nvram boot-args="-s" will result in single user boot.
As for creating administrator priveleges for my new user account, I've found a method which looks good:
     \single user mode\
     cmd-s
     \mount drive\
     mount -uw
     \open 'directory access'\
     lauchctl load /System/Library/LaunchDaemons/com.apple.opendirectory.plist
     \list users\
     ls /Users
     \change password\
     dscl . passwd /Users/<username> <password>
I think that this method intends that if I change the root users password I'll be changing the administrator password (as root is the only user with administrator priveleges), and subsequently be able to change my new user accounts priveleges using 'netinfomanager'. But I'm not 100%. Could you give me your opinion on this?
Furthermore, three keys 'L' 'O' and '(' aren't working on my keyboard, which means I can't try this until I find an intact keyboard to borrow. I was thinking maybe a mod version of the above instructions would work in terminal using sudo, so I could use the keyboard viewer to type the missing characters. If you have any ideas on constructing such a mod I would be interested to hear them.
Otherwise, Thank You for your help BDAqua! And enjoy your summer wherever you are.
