7220 printer suddenly doesn't recognize ink tank

My 7220 printer is several years old, and I have had no problem using third-party ink tank refills. Now, suddenly, I have gotten a "does not recognize ink tank" message, and the light is off inside for the large PGBK ink tank that is still about 1/3 full. Replacing it with a new ink tank results in the same message. Ideas? Thanks.

Hi Kanzas,
You can try removing and reseating all of the ink tanks and the print head in the printer to see if the ink tank will be recognized; however, we cannot guarantee the quality, reliablity or compatibility of third-party ink being used in the printer, even if Canon genuine ink tanks are being used but are refilled with remanufactured ink. Sometimes during the ink refill process, the original ink tanks can be damaged and not function properly once reinstalled in the printer.
If reseating the ink tanks and print head in the printer did not work, replacing the ink tank with a new Canon genuine ink tank may resolve the issue. If you continue to experience difficulty, the printer may require servicing; please call or email us using one of the methods on the Contact Us page for further assistance.

My desktop all of the sudden doesn't recognize my iPod Nano when I plug it in (gives me an error message). I've tried everything! HELP!

Up until yesterday, my nano was syncing just fine with my iTunes. Out of the blue my brand new desktop doesn't recognize my iPod Nano device. I have tried uninstalling/reinstalling iTunes. I've worked through all the diagnostics apple had to offer... but nothing. Can you help?

Does this problematic song play okay in iTunes? Have you tried removing and resyncing it to your device via iTunes?

TS3048 Printer/Scanner doesn't recognize my iMac

I have a Canon MX350 wifi printer that my MacAir recognizes but not my iMac. Both are on OS X 10.7.4 snow leopard. It's a pain to get anything printed right now - I have to grab everything through the MacAir since I can't print or scan directly from the iMac. What do I do?

So in the iMac, when you open Print & Scan and select to add a printer, does the MX350 show as a Nearby Printer? If not and you click Add Printer or Scanner, the Default Add Printer window will appear. Does the MX show here?

Printer doesn't recognize ink

Just replaced yellow ink in Photosmart 5180 -- I'm sure its the right thing, its brand new and I shook it and some ink came out-- but printer insists there is no yellow ink.
Ideas?

I feel your pain. I have a new 6500 (six months I've used it). Everytime I insert a brand-new GENUINE HP cartridge - these happen to be 920's - the printer does not recognize it. Says it's "damaged" or whatever and tells me consult manual.
The manual (at least on 6500) says to clean the little "window" on the cartridge. Mind you, this is a brand new freshly unwrapped EXPENSIVE HP catridge and I gotta do maintenance on it before I stick in the machine? So I get some eyeglass cleaner and rub it on the little "window" (it's very cloudy and dark for a window, looks like solid plastic) and then the printer accepts it. Like it just saw its passport and determines its not an illegal alien cartridge.
BUT - and here's the rub (no pun intended)...even after I did that three times or more on a cyan cartridge, the 6500 would still not accept it. I didn't have time to mess around anymore so I bought a new one. Fortunately, that was accepted. I put the cyan that wouldn't work in a baggy and sealed it.
After Christmas, I called HP at the toll free number in the manual (1-800-474-6836). On the phone for an HOUR OR MORE! First, with some guy who couldn't speak clear English (although I think it was an India support center) and then he gave me to his supervisor, a "Lisa" who, when I then asked, "Am I the only one on the planet with this problem?" She says, "Honestly, this is the FIRST I've heard of this."
Give me a break...not only are 6500 owners complaining on this but so are owners of other HP printers like yourself.
Back to the cyan in the baggy: The one I installed successfully was now empty and before buying a new one I opened the baggy and cleaned the livin' H out of that window with alcohol. This is after I drank some of the drinkable kind of alcohol. ALAS..the 6500 finally accepted that cyan cart from the baggy. Then I had another drink in celebration.
But, come on, HP, do I have to go this crap every time I try to install a brand new cart? With HP lacking advice on this, my next move is to talk to the Cartridge World shop in town and see what they know about the 920s. That might be an idea for you, 'cause, so far, HP is of no help.
If this keeps up, I'm going out and buying Canon's $99 (at Walmart or Best Buy) new all-in-one and seeing if I can peddle the 6500 to somebody who loves to do play the "let's see if this HP cartridge will work" game every stinkin' time a cartridge is loaded. Frankly, I don't have that kind of time or patience and it would be worth the cost of one HP ink 4-pack to go back to Canon, a manufacturer that did not give me these problems on my last printer.
Good luck.

Siri suddenly doesn't recognize most of my contacts

Over the last few weeks, I have been unable to get Siri to recognize even the most simple of names in my address book. It is quite infuriating. These are names like Cory or Jessica. It instead finds some similar word in the dictionary and says I have nothing in my address book that matches and would I like to search for businesses with that word.
I tried turning Siri off and then back on, thinking it might reset something on apple's end, but same result.
It seems to be fine for contacts I've taught Siri are related to me like "call my brother." But virtually every other contact name isn't working. Any ideas?

Siri does this to me, too. E.g., I call Nena Smith several times a week. One day, it said "sorry, there is no Nena Smith in your contact list" which was ridiculout. After several requests (and blood pressure going through the roof of my car) I was able to turn off the phone and then turn it back on. After the reboot, Siri again recognized that Nena was in my contact book by the time I pulled up to her house.
Funnily enough, today I called Nena again. I say "Call Nena Smith" and Siri says "do you want to call Laura Smith?" and I say NO! and Siri says "whom do you wish to call?" and I say Nena Smith, and Siri says, "do you want to call Laura Smith . . . and we're off. It refuses to call Nena Smith and will only call Laura (a person I seldom call). I rebooted, but that didn't solve it.
Another one: Call Ann Roberts.
There is no Ann Roberts in your contact list. Would you like to call Robert Jones or Ann Roberts?
Even if I say Ann Robertssssssss it refuses to call her!
What is wrong with Siri? These are only two of many examples.
And more important, even with humans with a problem, the important question is
How do I fix this?
Thanks.

Iphoto suddenly doesn't recognize my photo library

Yesterday, I created a slideshow and showed it on our TV via the s-video output and screen mirroring. When finished, I returned the screen settings (ie resolution) to what it had been (1280x854).
Today, when I opened iphoto, a message appeared "Screen resolution is not optimal for iphoto". The only option was to click "OK" which I did. After clicking, the slideshow that I had created appeared in iphoto but there was no way to open my other photos/events. I subsequently tried to import a few extra photos from pictures. They were imported but the rest of the library did not appear. I subsequently deleted them. Now whenever I open iphoto (by clicking on the iphoto app. or on the iphoto library in Mac HD), the screen is blank and there is an indication of "no photos". However, if I click on iphoto library in the HD without opening it, library size is listed as 14 GB. Also, if I click on "search all images" all of my photos appear and can be opened by Preview. What is going on, how did it happen and how can I correct it?
Thanks, Gordon Kus

Hold down the option (or alt) key and launch iPhoto. From the resulting menu select 'Choose Library' and navigate to the iPhoto Library - which is in your Pictures Folder, by default. If iPhoto sees a valid library there it will open it. If it doesn't then you have a damaged database file:
Try these in order - from best option on down...
1. Do you have an up-to-date back up? If so, try copy the library6.iphoto file from the back up to the iPhoto Library (Right Click -> Show Package Contents) allowing it to overwrite the damaged file.
2. Download iPhoto Library Manager and use its rebuild function. This will create a new library based on data in the albumdata.xml file. Not everything will be brought over - no slideshows, books or calendars, for instance - but it should get all your albums back.
3. If neither of these work then you'll need to create and populate a new library.
To create and populate a new library:
Note this will give you a working library with the same Events and pictures as before, however, you will lose your albums, keywords, modified versions, books, calendars etc.
In the iPhoto Preferences -> Events Uncheck the box at 'Imported Items from the Finder'
Move the iPhoto Library to the desktop
Launch iPhoto. It will ask if you wish to create a new Library. Say Yes.
Go into the iPhoto Library (Right Click -> Show Package Contents) on your desktop and find the Originals folder. From the Originals folder drag the individual Event Folders to the iPhoto Window and it will recreate them in the new library.
When you're sure all is well you can delete the iPhoto Library on your desktop.
In the future, in addition to your usual back up routine, you might like to make a copy of the library6.iPhoto file whenever you have made changes to the library as protection against database corruption.

MacBook Air suddenly doesn't recognize my keychain passwords. Now iCloud, Safari and anything associated (including Systems Preferences) won't work. Plz help - any ideas?

The only thing I can think that I've done differently is that I'd downloaded a scanner driver from Canon. Everything worked fine for days after that. It wasn't until I shut down the computer and restarted it that I keep getting these prompts to enter keychain passwords and it rejects the only passwords I've ever used. No idea what to do. Any help would be greatly appreciated! :-)

I just found the fix in another post! Here it is, in case anyone has the same issue...

My derived class suddenly doesn't recognize the parent class

I had my assignment coded, debugged, working and ready to go. So I bring my flash drive upstairs to play around with it on my other computer. When I compile the base class it compiles fine, but now when I try to compile the derived class, and the test class with the main method, I'm coming up with errors.
They have something to do with the base class not being recognized, because I can't instantiate any objects of the class now, and i get an error when attempting to compile the derived class to the effect of "cannot find symbol; symbol: class BaseClass". i get this error throughout the derived class, from the initial declaration of the class (public class DerivedClass extends BaseClass), to any references made toward methods of the parent class.
My base class compiles with no problem, but it's like nothing else is able to "use" it. I'm not sure if it has something to do with the PC im using now, and I can't confirm this at the moment because the PC I used to write the code is down (waiting on an upgrade).
ehhh.....help.

It's not the fault of the computer hardware.
It's not the fault of the operating system.
It's not the fault of the JDK.
So don't go rebooting or reinstalling anything. The problem is that you didn't set up things on the new computer in the same way they were set up on the old computer.
In particular the compiling problem is that the compiled version of BaseClass isn't in the classpath when you try to compile DerivedClass. I can't tell why from your description.

Lightroom 5 suddenly doesn't recognize my serial number.... Help?

I get this message when I try to open lightroom on my computer (I've had lightroom 5 installed on this computer for a full year, and not the cloud version):
"The serial number you entered is invalid. Please try again."
It won't ever work. It is the correct serial number.
Help is appreciated!

I was using the trial version, which recently ran out. Loved the software, so a couple of hours ago I purchased a standard license via download from Amazon.
Amazon sent me what appears to be a valid license key (6 groups of 4 digits). But Lightroom will not accept the key, with the exact same error message as you in your post.
I've sent Amazon an email message. Meanwhile, I have phoned Adobe Support...and I have been on hold for over an hour, without being able to speak to a live support agent. Your phone sucks, Adobe.
I wonder if something's gone wrong with their licensing/validation system.
Adobe?

IBook G4 screen goes black, suddenly doesn't recognize input

Last night I was using my ibook in the usual manner, in the middle of sending a file to a friend, when my screen went black as if it were going into a screen saver, but wouldn't respond. The backlight was still on, but it seemed to be frozen. I force shut it down, tried to turn it back on. The backlight came on, and it seemed to be starting up, but no picture appeared. Tried again. The second time it didn't turn the backlight on at all, and wouldn't respond. I figured maybe it had just overheated. I let it rest for a couple of hours, then tried again. This time it went to the startup screen, and I figured it was alright and had just overheated or something. But a few minutes after I entered my password and it loaded my desktop and everything, it went back into the backlit black screen. I left it off for the night because I wasn't sure what was happening.
This morning I turned it on and the first time, the backlight turned on, but no activity. The second time, the backlight wouldn't turn on. Same thing the third time. Decided to try to boot off the install cd, and though it didn't boot from it, it started up fine and things seem to be working so far. I'm just afraid it's going to happen again. Does anyone have any suggestions?

Welcome to Apple Discussions.
I've had to rely on keeping it plugged in for power for the last 2.5 years or so since my battery no longer holds a charge.
Please buy a new battery. You owe it to your computer and to yourself. Even though it will run when plugged into household electricity, that is not how the computer was designed to operate.
Also, if I look close enough at the screen, I can make out the desk top slightly; it's like the brightness is setting is way low, when it is actually on the brightest setting. The screen goes black in the same way if I leave the computer on, but unattended for like 5 minutes.
Go to Apple Menu > System Preferences > Energy Saver and check the settings under the Power Adapter tab as well as the Battery tab. You may want to reset the Power Adapter so that the monitor stays on for longer.

Suddenly iPad mini doesn't recognize my wifi

IPad suddenly doesn't recognize wifi

Try to reboot your ipad? Hold down the sleep and home keys for about 20 seconds. When you see the silver apple, let go and let it reboot and try again
You can also try to power cycle your router. Unplug the power to the router, count to ten, plug it back in and let it reboot and try again.

Media Encoder suddenly won't recognize Quicktime files...

Hi there...
I'm on a Mac, and out of the blue, Media Encoder suddenly doesn't recognize Quicktime .mov files. It says this file format is not supported. Which is weird, because it was supporting it just fine this morning! Does anyone know what might be wrong or how to fix this?
Thanks for your help!

Im having the same issue. Were you able to resolve it?

My bb8250 doesn't recognize my password

Hi there, I really hope you can help me with the following. My bb8250 all of the sudden doesn't recognize my password anymore. It all started when I downloaded the BB desktop-manager on my mac. My mac wanted my device-password but didn't recognize it. Then I disconnected the two and now my bb doesn't recognize my password either! To be precize: it does recognize my device-password. But I can not get it of the handheld lock. When I type my password it doesn't show the normal small stars but shows letters where I want to enter cijfers instead of the stars. When I use the alt button to enter the right code my bb doesn't recognize it anyway. I've tried rebooting it by getting the battery out. That didn't help. Now I've only two shots left to enter the right password. I'm trying not to freak out, but it's half a child's life in photo's on there, so I would really really really really like to get into my bb again. Please could you help me out? Thank you so much in advance! Kind regards, K.
Solved!
Go to Solution.

I'm back in! Always thought I had a 4-cijfer-password. I was wrong! I changed each cijfer into the letter on the same key and filled that in as my password and it worked! Yeeeh!
