I use Wordperfect, and have for a very long time. That doesn't mean, however, your answer doesn't fit. I'll have to see what happens when I test-print an envelope again via WP. Your suggestion puts me to thinking about the fact the usual order is to print the letter, then the envelope and then leave the word processing program. Under those circumstances the reset would happen automatically. However, I printed the letter, then the envelope, then editted the letter and when I tried to print it, I got the message.
As far as "canceling from the control panel", I just hit Cancel a couple of times until the error message went away and then printed.
Is this an issue in MS Office? Because MS Office will hold last-used settings, not the driver defaults, until the application in question is re-started. (Word, Excel, Publisher)
MS applications are the only regular ones that do this.
Not sure what you mean by canceling print via the control panel though, if you printed the job there is no job to cancel, and if there is a job, you haven't finished printing so the envelope is still needed.
Now if the job you cancel is a new job that should have been Letter size, then the above applies, either choose to print regular paper in MS Office and the driver, or restart the application.
This is my second ColorQube - the first was an 8570, which I owned for 5+ years. They both seem to have the same problem., namely, when I print an envelope, once the envelope is printed, I keep getting the message the tray I just used to print the envelope is out of paper. Once I've printed the envelope, I go back to using standard 8-1/2 by 11 inch paper, but there doesn't seem to be anything that tells the printer I've done so. The answer I've found is to just cancel printing via the control panel. That seems very non-intuitive. and. it would seem to me, there has to be a way to get the printer to switch at least semi-automatically. Anyone have an answer?
