to clarify, does this happen with all accounts on all computers? ...and did it begin happening all at once?
Can you tell me the exact version of OS X you are currently running on each Mac, please?
Click the Apple logo in the menu bar at the top left of the screen
Select "About This Mac"
In the window that opens, look for the "Version" information. Please let me know what it says.
Can you please download and run the following tool on your Mac?
It will collect information about your system for diagnostic purposes.
Run the app once it has downloaded
On the first screen, feel free to choose a problem but you can leave description blank since you’ve already told me. Next, click “Start EtreCheck”.
When it is finished collecting data, click “Share Report” and choose "Copy report to clipboard"
Then click “I Accept” and paste it back to me as a reply. (You should be able to paste it back by right-clicking or Ctrl-clicking where you type your reply to me and then choosing Paste from the pop-up menu).
can you please try running OS X in Safe Boot mode for a bit and see how Mail behaves then?
Restart your Mac
As soon as you hear the Startup chime, press and hold the SHIFT key
Continue to hold the Shift key until you see the Apple logo and progress indicator.
Then, let go of the Shift key and let it boot to the Desktop (it may take longer than usual so please be patient).
Once you've finished putting mail through it's paces, restart your Mac and let me know the results.
Thanks, ***** ***** going to opt out so an expert with fresh eyes can handle this question. When one becomes available, they will contact you.
Please do not reply back until you hear from them as it may delay the transition.
Thanks and good luck!
Sorry you are having this issue, there is a censor inside that looks for paper, these often times fail. This type of behavior is a hardware problem on the printer, it has nothing to do with your PC. Depending on how old this is, and rather you would rather fix it or buy a new one (the price to fix it may be a s much as a new one) will dictate your next move.
I'm so sorry, I posted this to the wrong question.
