MacBook Air :: Canon Wireless "A Communication Error Has Occurred"
Apr 29, 2012
We have a Canon MG8120B printer on our wireless network, using a Time Capsule as the WiFi hub. Printing from the 27" iMac has never had a problem. But from our 11" MacBook Air (late 2010), it fails about half the time, simply saying "A communication error has occurred". Pausing the print queue and resuming it will eventually get the print job to succeed, but it's a pain, and I do not understand why the two machines act differently.
Info:
MacBook Air (11-inch Late 2010), Mac OS X (10.7.3)

I have a canon mx700 printer.I just upgraded to snow leopard 10.6.8 and now my printer is no longer working.This is probably the 50th time I have had this problem. It always occurs whenever I update my apple software. I have tried reseting my settings, updating my drives and trying to connect the printer directly into my computer and over my network without any success. Upon resetting my drives I keep getting this error a communication error has occurred.

I have a Canon 780 installed which seemed to print fine for a while, but now when I try to print I get:Error Number : 306 A communication error has occurred. Make sure that the printer is plugged in, powered-on, and properly connected to your computer. Then try printing again.The printer is connected via a USB Hub, but plugging it directly into the USB Port doesn't seem to help either. I've also made sure I "woke up" the printer, plugged, replugged, etc.If I mess around plugging and unplugging, it eventually will work.

I switched my EpsonR320 from my PC (where it works fine) to my Mac Mini. I downloaded the proper driver. It just says "communication error" when I try to print. I've tried several printer cables, to no avail. If I bring up the printer window it says "printer ready", until I actually ask it to print and then I get that error message.

I am getting this error "The operation can’t be completed because an unexpected error occurred (error code -50)." when I try to transfer files from my Mac Mini to my External Harddrive which is connected to my Airport Extreme. " The error does not appear to happen all the time. It does seem consistent if I am transfering files and then try to transfer more.
The files I am transferring are .mp4. It does not appear to care about the size of the file, it happens with small files and large files, I can transfer some large folders (2.54G). I can connect the hard-drive externally directly to the mac mini and it will transfer any file.

I am getting this message when I try to open the "messages" on my macbook pro: "An internal Messages error occurred." It doesn't give me anymore information and tells me I have to quit the program and restart. I do so and still get the same response. I have updated to the latest version of Yosemite and restarted the computer. This is a new issue that just arose today when I turned on my computer. I have been using messages, including the new text forwarding feature flawlessly since Yosemite's release and even before that for iMessages with mavericks.

I have a 2.3 GHz Intel Core i5 Mac book Pro, I changed the hard disk once, and now when I tried to update it, it always says "An unexpected error occurred" And the only button for me is the "Restart button" (Remember, I always have my Wifi on). Is it because of the hard disk changing or because of something else?

I'd love to use the integration of Youtube into IMovie '08. But when I finished a movie, filled in all the required data like username and password under "Share", "Youtube", after rendering and trying to uploade the movie for a while. IMovie displays a "Communication Error" and asks me to try again. But of course we know how computers work: Not changing anything and simply following this advice simply leads to the same error again. I'm on a MBP with a LAN connection to the internet. My upstream speed is 1 megabit/s. Uploading movies manually to Youtube using the web interface works flawless and fast.

I have a Canon MP560 wireless printer. For several years the printer has been on my wireless network and has been used successfully by several Windows laptops. I recently purchased a used Macbook Pro and I would like to be able to print wirelessly to this printer. The Macbook pro is successfully connected to the same wireless network that the printer is on. I have read through many, many articles and forum posts on how to get this working but I am unable to. When I go in to the system preferences>printers to add the wireless printer it never shows it as an available device. I have done the following:
1. updated to the latest OS X 10.9.5
2. installed the latest driver for the printer from canon's website
3. Downloaded the latest canon inkjet printer software update from the app store
4. reset the printing system several times
5. I have plugged the printer directly in to the Macbook via USB cable
When I have the printer plugged in via USB it is shown in the list of printers and works fine. But when I disconnect the USB cable it shows the printer as offline and I see no way to have the printer available as a wireless printer. If I click the + button to add a printer there are no printers to select to be added.
I have gone through the steps in several forum postings including this one: MacBook Air won't find HP wireless printer and similar other ones but so far nothing has solved this issue.

A movie I purchased stops downloading almost immediately and the error message above comes up. The rest of iTunes works properly and my internet connection is fine. I was downloading numerous TV episodes before and during while this movie was in the cue without any issues. I've restarted my network and that did not seem to fix it.
I've deleted the movie from the cue and re-downloaded it but still same issue.

I have a 60GB iPod w/photo capability and the newest software (1.2.1), iTunes (6.0.4), and iPhoto (5.0.4). Whenever I plug in my iPod recently it gives me an error message: "The iPod "iPod" cannot be updated. An unknown error occurred (-50)." I have tried both USB ports. Didn't work. I have reset the iPod. Didn't work. I have restored the iPod. Didn't work. The iPod loaded my songs but the iPod would not load my photos from iPhoto (and, consequently, my Address Book contacts since they are done after photos). So it seems to be a problem with iTunes-iPhoto-iPod. I have also on a suggestion used Disk Utility to partition my iPod. Didn't work.

Friday, when I tried to enter my computer I have received a log screen. Tried to log but I have received this message "you are unable to log in to the user account "user" at this time because an error occurred" (never happened before). I am sure that the password is correct because the screen doesn't shake, like it happens when I introduce a wrong password. Tried to reboot with "apple S" pressed to go to the root. When I access the directory "Users" I cannot see my user name anymore. Filevault is not activated, never did it. I have very important data from work (my whole year work), I don't have backup and I must not loose it. I was not trying to do an updade or anything, it just happen when I turn on the Mac.
I have tried to do the following things too:
Boot from installation disk #1: Accessed Disk Utility and repaired the disk. There was one error "Mounting of the drive" that was fixed. No other errors found. When I rebooted I got the same message at the login screen. Tried to change the password. I got an error telling me that I don't have permission or an error has occurred. The volume Macintosh HD appears to be ok. Rebooted and still had the same problem.

I am using Mac OS X 10.5.8. I had a program that was working perfectly, I tried to update it. Why? - I dunno myself. Anyway, now I can't open the program. When I try to delete it I get the message "sorry, the operation could not be complete because an unexpected error occurred. (Error code -61)." I made sure the program was "forced quit," but this made no difference at all. I tried to make the files "shares" files and not "locked" files in the "get info" tab, but it still doesn't allow me to delete them. Any idea of how I can get rid of this program now?
