HP Laserjet 4015 / 4015tn says paper jam in tray 3, but there is no jam and will not print until power cycled.
I have a HP Laserjet 4015tn printer that will print one page from tray 3, but immediately after says printer jam in tray 3 and will not work (when printing to ANY tray) until power cycled. There appears to be no jammed paper. After power cycling you can go on to print from tray 2 and the manual feed tray 1 with no problem. I have updated all drivers and the device's firmware to the latest versions.
