I cannot print to my wireless Canon printer. A communication error has occurred.

I have had no problems printing to my wireless Canon printer until yesterday. Now when I try to print the icon at the bottom shows a printing job has been started but nothing ever prints. When I open the print cache it tells me that "A communication error has occurred." I've checked the printer and it is still set up properly. I have unplugged my wireless router and modem to reset, but this has not interrupted my ability to access internet nor has it reset the printer to a different setting. I am at a loss as to why I can't print any longer. Since we bought the mac in July I haven't had any problems and this really has thrown me for a loop as to why it is occuring. Any thoughts would be greatly appreciated.

Perhaps one of the printer drivers is corrupt. Go to http://www.canon.com.au/en-AU/Support-Services/Drivers-and-Downloads (or other country download).

Canon MX340 wireless printer no longer connecting over wireless and coming up with "a communications error has occured"

I have a Canon MX340 wireless printer and have only recently started having trouble printing over the wireless connection. No settings have changed on my MacBook Pro, the printer, the router or the wifi connection and it is strange how it has just stopped working. I have tried things like restarting the laptop and removing the printer from the laptop and re-adding it. It sometimes seems to work for maybe one print but then it goes back to saying "a communications error has occured", when I try to print again.
Any help would be great. Thanks

I had the same MX340 problem. My printer was working fine over WiFi connection to my Airport Extreme for years and then suddenly, about a month ago, it stopped printing after the first print job. I can print once and then I have to power-cycle the printer to get it to print another time and then I have to repeat the power-cycle.
The printer seems to be "forgotten" by the network or lose its connection after the first print job.
On my MacBookPro 10.6.8 I get the error code 300...yadayadayad... On my iMac 10.5.8 it just says :communications error".
HERE IS THE FIX - I got it off this link - http://www.techsurvivors.net/forums/index.php?showtopic=24681
You have to connect to the MX340 using the printer cable that came with the printer (or any USB printer cable) and set up a hardwired USB printer queue. Then print a couple of print jobs - I use TextEdit and type in "1234". Then try the same thing but select your WiFi print queue - I just type another line on the same sheet of paper with TextEdit.
The WiFi connection should work again. I did this a few more times and then disconnected the USB cable and now it continues to work without the USB print queue being used. I can also print to the WiFi queue with my iMac.
If you still have problems I suggest you set up the printer again on the WiFi router using the "print cable connection" method. Here's a link to a webpage someone kindly provided instructions for the process:

Communication error has occurred - Canon PIXMA printer

This was driving me nuts! I tried many of the other ideas offered in these discussions, but nothing worked. Sometimes my Canon PIXMA MP640 WiFi printer would work, usually it wouldn't. I would get "A communication error has occurred" message on my MacBook Pro (Snow Leopard) and the print job would just stay in the queue until I deleted it. Most of the time I needed to re-enter the network password at the printer BEFORE EVERY PRINT JOB which was a pain because the password was 10 characters long and I could only dial in each letter one at a time.
If you are having similar trouble, before you do anything CHECK THE WIFI SIGNAL STRENGTH USING THE PRINTER MENUS! On my model, this was done by going from the Home menu to Settings->Device Settings->LAN Settings->Confirm LAN settings->Print LAN Details. If the signal strength on the printout shows less than 50%, there is too much interference from other electronics in the area (or the printer is too far from the router). In my case, the printer was in the next room, i.e., not too far from the router so I knew it had to be EM interference.
At first, my signal strength was showing 36%. Then I moved the printer into the same room as the wifi router, within 7ft and directly in line of sight of it and it went to 62%. I thought it should be much higher, so I moved the printer to within 4ft and it went to 80%. Then I unplugged the LCD TV (which was NOT turned on at any time) that was on the counter nearby, and it jumped to 90%.
After months of poking at this problem and finally resigning to the idea that the printer was broken, I tried this and now it works perfectly as long as the TV is unplugged. I plan on moving the router away from the TV so I won't have to unplug it whenever I print.
Hope this helps!

I've wrestled with this off and on with this printer ever since I got it. Just checked and my signal was at 44%. Guess that could be it!... guess I'll do some relocating of the router, boost the signal or run an ethernet line. Never though the signal being that low would cause this many print errors.
I thought is was just happening when the printer would go to sleep... or not used for a few days.
Thanks!

Canon Pixma displays "A communication error has occurred"

I have a Macbook Pro running 10.6.8 and a Canon Pixma MG 5220. Both are connected to a Linksys E1000 wireless router. I have had a lot of problems getting this printer to connect wirelessly with my MB. I have searched the internet for answers tirelessly and tried the suggestions that I found; however, nothing has seemed to remedy the problem.
I have set up the printer according to it's directions step-by-step. Using my CiscoConnect application, I added the printer to my network. I have entered in the network name and password into the printer and it tells me that it is connected. I used the CD that came with the printer to install the necessary drivers and add the printer. I have gone into my System Preferences and added the printer that way. Any time I try to print, the error message "A communication error has occurred" comes up in my printer queue. I have the printer added with the USB connection just fine, but it is irritating to have to get up and connect my laptop when this is a wireless printer. Once I have the USB printer added, I cannot add the printer wirelessly. All I see is "Bonjour Scanner." I have checked the signal strength, and it is fine. I have used the Network Utility to ping the IP address and it is fine as well. What is going on with my printer????

Cannot connect to the phone system. An unidentified error has occurred, Please try again.

Issue: Lync 2013 users with remote call control enabled cannot connect to the phone system. When the user logs into Lync, they see an exclamation in the bottom right corner
with this error.
Error: Cannot connect to the phone system. An unidentified error has occurred, Please try again. If the problem continues, please contact your support team.
Environment:
1 site: Site1
2 Pools:
1. Lync 2010
Trusted application is added here for the site.
2. Lync 2013
Avaya phone system: AES r6-1-2-32-0
I have not moved the trusted application to the Lync 2013 pool yet, but my understanding is that it should still work since it’s in the site. Is my understanding on this correct? (All of my other trusted applications do work for Lync 2013
users & none of them have been moved yet. Remote Call Control is the only one that does not work.)
This is from the uccapi log. This is just from the user logging in, not actually making a call. Below are the items that I think are important, however, I don’t know how to interpret it to determine if the problem is on the Lync side or
the Avaya side. Here’s a summary:

Hi Suelizy,
To better understand the issue, I would like to collect the following information for troubleshooting:
1. Do you mean the Lync 2010 user can connect to the Phone System?
2. What’s next hop pool of the application?
In a mixed environment, you must set the next hop pool to be the Lync Server 2013 pool.
Best regards,
Eric

Cannot export from Lightroom 5.6 to jpg, Internal error has occurred, attempt to perform arithmetic on a nil value

Hi everybody,
I run Lightroom 5.6 on Windows 8.1. It's been a while since I exported anything and now I find that I cannot export to JPG.
I get an internal error, " attempt to perform arithmetic on a nil value" .
I remember that I used to have this situation before (different error) with previous versions. Than it was usually the "perform after export" that was without value.
However it is set ti " Do nothing" .
I've searched the web and found nothing. Anyone got an idea what the cause could be?
Thanks
Bob

Hi there,
so I found something! I was wondering why the "publish on harddrive" process did work, but the export to harddrive not.
So I looked in the difference of the presettings and found only the different options "choose export folder" and "predefined export folder" (don't know the exact translations, as I use the german version, but I hope you find what I mean.)
So I changed in the export settings the export folder to a fix predefined folder and there you are, export is working again!
Don't know the relation to the GPS-data, but anyhow.
Hope this helps to solve the problem?
Don't know if MS windows did an update which causes the error, but I didn't changed anything in lightroom as it worked before without these settings.
And of course in the long rund I would like to go back to the "choose folder" option, as I know have to copy the images to the right folder after export which is not a smooth process..
regards
_ulf

TS1368 "Cannot connect to the iTunes Store. An unknown error has occurred."

"Cannot connect to the iTunes , & I can't download any thing

I am getting the same in Denton, TX on both my iPad3 and Apple TV.

I keep on getting "Cannot connect to the iTunes Store. An unknown error has occurred."(-50). What do i do?

Whenever i try to access the itunes store, it just stays on the page saying loading but never loads and then the error appears. What other ways can i access the itunes store to check my purchases account?

Thankyou for your help !!
i was also wondering, the reason im wanting to access the itunes store is to check my purchasing account because on my account balance ive been overcharged.
I was charged $1.00, but i read that this is for authorisation purposes of my debit cardand that it'll be refunded back to me over a few days. However ive only bought one app which was $1.19, yet i was charged double so $3.38. Do you know whats wrong??
Also how many days does it usually take for the email receipt to be sent to my email and is this email the apple ID email address??

Cannot log into iMessage or FaceTime it says an error has occured during activation

i could not send or receive iMessage would not let me log in to iMessage or FaceTime it says an error has occured during activation.

Hi Cam-Fox22,
I have had this problem and tried everything suggested without success until last night. I took the plunge and did a Factory reset which cured the problem. Of course you must do a back up to iTunes first. I connected the iPad to my PC via a cable and then loaded iTunes. Log in to the account associated with your iPad and then carry out a backup of your iPad including apps and purchases. Then hit reset option near the top of the page and hit again when asked if sure. It takes a while to download the software but eventually it wiped the iPad and loaded it with fresh software. Keep your iPad connected and then restore from back-up when given that option. When it is all finished you will have your iPad back just as it was before you started but with iMessage and Facetime both working again.
Good Luck John

Cannot log into iMessage or FaceTime it says an error has occured

iimessage was not delivering so tried to log back into iMessage and facetime but it tells me an error has occured during activation and to try again

Hello meganatherton2000,
Thanks for contributing to the Apple Support Communities.
It appears that you get an error when trying to activate iMessage and FaceTime on your iPad mini.
You mentioned that you signed out of iMessage and FaceTime because messages were not delivering. Be sure to restart your iPad mini before trying to sign back in to iMessages or FaceTime, as mentioned in this article:
If you get an error when trying to activate iMessage or FaceTime - Apple Support
Restart your device.
If this issue continues and iMessage can't be activated for more than an hour, the article above suggests contacting Apple Support:
Still not activated after an hour?
It might take a few minutes to activate iMessage and FaceTime. If you've waited more than an hour, try these steps:
Make sure that your device has the latest version of iOS.
If you're using an iPhone, contact your carrier to make sure that you can receive SMS messages.
Contact Apple Support.
Sincerely,
Jeremy

CANON PIXMA MP640 - Communication error after a print or two

I've been very happy with this wireless machine until the last couple of weeks, when I've begun getting "a communication error has occurred" in the print window.
I re-run the Canon setup CD, download the latest driver for Snow Leopard (10.26.2.0) and all is well - for one or two operations. Then the communication error returns....
I can't think of any particular new application or programme I've installed to provoke the issue.
It's become exasperating and I've resorted to using the USB connection, which defeats the purpose.
Any suggestions most welcome!

I had one "USB printer" set up, it worked like a charm.
I tried various "LAN printers", scanning worked fine, I could manage the printer, I could even print test pages (to check if the print nozzles where fine) from the management tool. But I could not print to the printer via LAN using the Print menu command.
I tried installing new driver software, it did not help. I tried reconfiguring the printer via the web interface. It did not help. I then tried deleting the "printers" I had created, except for the USB printer. I did the following:
1. Opened System Preferences, Print & Fax
2. Deleted all printers except the USB printer
3. Clicked the + to add a new printer
4. Selected the Default tab, and could then see the printer there.
5. I added that printer, and could then see the printer with the canonijnetwork added to it.
6. I added that, and now I can print using that "printer"!
Thanks a lot for the help. Please notice that, at least for me, it was essential to go to the Default tab and ad the printer from there, and that it was a two-step process (add the printer without canonijnetwork, then add it with canonijnetwork).
I wonder if anyone gets their MP640 printer to work via LAN or wireless without any problem (on OS X 10.6).
Anyhow, I can now also print successfully using LAN (the printer is connected to the router via LAN, my MacBook Pro is connected to the router wirelessly).

HT3500 i have a mac pro and have connected to my wireless canon printer. I was able to print but now the printer comes up with the paper in the tray is the wrong size. but the paper is A4. does any one know what is wrong.

I have connected to my wireless canon printer but it wont let me print from my mac pro. printer comes up with the message that the paper size doesnt match the printer settings. I have tried to change the settings on the printer but that didnt work. can anyone help

Well... no help was found here.. so I abandoned the wireless- ness of my printer. I bought a
small 10 port hub because only 2 USB ports really isn't enough with wireless mouse, wireless internet
and any kind of printer. I also bought a long USB cable. I now print--wired since this can be done
as an alternative to wireless with this printer. Because I don't want a cable "hanging around"
when the printer is not in use, I simple disconnect it and reconnect when I want to print.
It's a temporary solution others may find helpful as well. Apparently there's been a lot of
confusion and problems getting this printer set up wirelessly with our MacBooks.
Shame on HP for not helping us out!

I cannot print to my wireless Canon printer. A communication error has occurred.
