Q: Support Code:300 The printer does not respond

In the last 2 weeks I'm suddenly getting a frequent error message on my MacBook Pro when I try to print to my Canon MX860 printer which I connect to over my WiFi network.  This combination has worked flawlessly for several years, but now it suddenly keeps coming up with this "Support Code: 300" error. 

 

I have deleted the printer several times and reinstalled.  It will work for 12 hours or less and then I start getting the Support Code: 300 error again.

 

My notebook PC, sitting right beside my MacBook Pro, continues to print to this same printer with no issue.

 

Any suggestions?

MacBook Pro, Mac OS X (10.7.5)

    Does the printer work when connected via USB?

    Yes it does work correctly if I connect via USB.  It sporatically works correctly over the WiFi network, once I've deleted the printer and re-installed, but then usually over-night it goes back to giving me the "Support Code:300" error message. 

     

    I can't seem to find anything to indicate what this Support Code:300 error indicates.  The printer is not busy and is on-line since other computers are able to print to it.

     

    Thanks.

    The support code would only be meaningful to Canon support. Since the problem is intermittent, it most likely has something to do with network conditions. Turn off all wireless devices except the Mac, the printer, and the router, and try to eliminate other possible sources of interference:

    Test.

    Bartlett3000,

     

    Did you ever end up finding a fix for this?  I haven't been able to print wirelessly to my Canon MX870 for the past few weeks either and I can't figure out why.

     

    Would love to hear how your issue turned out!

    My problem is still occurring.  It appears to me to be something created by an Apple update.  It's hard to make updates and verify that they don't create some problem on older hardware.

     

    This is really too bad because my MX860 is a really good, and low cost printer.

     

    I've tried a lot of things so far but nothing that seems to keep the printer working longer than 24 hours, and it goes back to the "Support Code:300" which I'm pretty sure is an Apple code.

    Experiencing same problem. Appears to be recent.

    Here's what fixed my problem:

     

    After reading some stuff online, I learned that if it's been a while since you last printed something, an ink cartridge may be empty but not trigger a 'replace' message.  In fact, the ink level display will look fine and not indicate that the ink is low. 

     

    I manually opened up the printer to check on the ink cartridge levels and to my surprise, my yellow was out of ink.  After I popped in a new yellow cartridge, I got no more error message and was able to print through wifi again.

    Thanks for quick reply. Checked ink levels as recommended and replaced two low cartridges. Unfortunately this did not fix the problem. I have 4 macs at home and previously I have been able to print from any of them over wifi to this printer for years without incident, even when some cartridges were low or empty.    Now  I am suddenly unable to print from any of them.

    I too suddenly started receiving communication error 300 and was ready to throw the printer out the window.  Started when trying to print PDF (which seems to be most troublesome) and then nothing was working.  Tried the disk utility fix (which seemed to be doing lots of clean up and I had just installed a system update) and still got communication error.  Checked the ink well and one color was totally out so we replaced.  Then shut off everything on network (turned off router and modem and turned back on, restarted computer and printer) and we are printing again....not sure which one of the "fixes" actually fixed it.  Printer worked for years without issue (though we had a canon photo printer with constant problems in past) and started having commmunication issues about a year ago when we upgraded IOS system to Lion and like others, it will work for weeks and then suddendly issues emerge.    Very frustrating, however I have slowly learned that checking the forums usually has a fix for these things!

    Hi! I'm also getting this problem which has started only in the last couple of days. Evrything was fine for 2 years previously.

    I also just experienced the problem. Tried bouncing a few individual devices with no success.

     

    lifted cover on printer to check cartridges and bounced everything router/mac/printer etc. and now it works again!

    The Support Code 300 error just appeared with my Canon MX870. Here's how I fixed it. Go to Print and Scan in System Preferences. The printer should appear in the list at top left. Highlight it and delete it by hitting the "-" button at bottom left. After confirming the delete, hit the "+" button. When the Mac finds the printer, add it. Try printing, it should work now. I had to do this a year or so ago too for a similiar communication problem. It's worked both times.

    This was my problem.  I knew it wasn't the WiFi since the scanner feature worked fine. I had not tried to copy anything.  The black (double) cartridge was completely empty though it showed 1/2 full  on the display.  Upon replacing cartridge, it still did not work.  I restarted both computer and printer....still did not work.  Took TBannor's advice on deleting and adding the printer and it worked though my Mac did not find it, I had to type it in manually. Thanks to you both for solving my problem!
