On HP printers with powered envelope feeders, we have received some reports that the type of media in the feeder is not being detected correctly, so a prompt to load Letter in the feeder appears. The fix appears to be to change the default media in the feeder: on the Device Settings tab, in the "Form to Tray Assignment" section, change Envelope Feeder to Envelope #10. We are also aware that printing from the envelope feeder may be very slow unless you change another setting: on the Print tab, from the menu at left choose "Adjust Paper Types", then scroll down the list to find Envelope. Change its Print Mode setting to Normal Mode; the Resistance Mode and Humidity Mode should already be Normal Mode.
PCL5 Exception
One HP LaserJet printer on campus has to use the alternative PCL5 driver, instead of the usual PCL6 driver, in order to print forms correctly from Colleague. That print queue is LEIG109-LJM602 (and its backup, LEIG128-LJM602). The PCL5 Universal Print Driver is downloaded from the same location at the same time as the PCL6 driver; however, its internal version number is frequently lower.
