For this issue, you need to make sure that the correct paper listed on the driver (type, size, orientation) match exactly to what is listed in the tray. So be sure to load the paper in the bypass to exactly match the driver settings. Also by doing this, the next persons job, won't start printing on the special paper loaded in the bypass as the settings shouldn't match.
1) When I put a check in bypass and print, it will not print. Rather it always shows "click OK to set bypass to plain white paper" before it prints. This is especially a problem because...
2) The printer is in frequent use. The ONLY time I want it to pull from Bypass is when I am "telling it to use Bypass." But it does the reverse. So I put in a check, try to print it, and then someone else tries to print... it will hold up both jobs (no surprise) but when I hit OK on the panel, it will then try to print BOTH jobs on bypass, even though I did not send the second job to the bypass tray! That causes problems either because the bypass has no paper or (worse) because it accidentally prints on check stock.
I'm using the Xerox Postscript driver, not a generic driver. Win10 Pro x64.
I have Bypass tray set to
Tray Mode = ON
Auto Select = ON
Priority = 4
Paper: White, Letter
