I have a HP LaserJet 4250 that the Tray 1 media tray has stopped feeding automatically. It used to pull when paper was put in it. Now, you have to setup a profile for it to change over to pull from the tray 1. What would cause this to change?
Hello,
Here is the info from the service manual about tray configuration.
The value corresponds to the media size that is currently loaded in tray 1. ANY: If both the type and size for tray 1 are set to ANY, the printer will pull media from tray 1 first if media is loaded in the tray. A size other than ANY: The printer does not pull from tray 1 unless the type or size of the print job matches the type or size loaded in this tray.
So set both the paper size and type on tray one to "ANY" and you should be good to go.
I hope this helps, if so please rate my solution.
I have the full service manual available for instant download for $6.95 if you are interested.
