Paper Coming from wrong tray for incoming faxes

The lower tray (2)is for PLAIN paper, the upper tray(1)is for printed special paper. Copy paper is taken from Lower tray but incoming fax paper is taken from upper tray. This is not what occurred on my 7140xi where both copy and fax and 3/4 of normal printing came from the lower tray. It should be obvious to most mortals that incoming faxes should be printed on plain paper but not as yet to the boffins at HP who insist that the machine is operating as designed. HELP! PS Although there is an option to change the copy paper to come from either the top or bottom tray, there is no such option for incoming faxes.

    Yes, I'm seeing this same behavior. Even though Tray 1 is the one with paper sensors that supports multiple paper types, both FAXes and even configuration reports and FAX logs insist on printing on whatever is in Tray 1, even when it's HP 4x6 Photo paper that is loaded.

    As though not only does the FAX feature ignore the "Default tray" configuration setting for the printer as a whole, but it also ignores the FAX-specific "Paper size" setting of "Letter" and prints on any size paper that is loaded.

    Either of which are issues HP can address in the L7780 firmware. Losing whatever FAX happens to come in while I'm printing photos (because HP has 250 sheets of plain paper available that it chooses not to use, and instead prints the FAX on 4x6 photo paper) is a bug, not by design.

    Best Solution 1 below is NOT a solution. I use tray 1 for envelopes and set the default in setup andd copy as tray 2. You can not use tray 2 for envelopes. All is well until a fax arrives and prints on an envelope. Called HP and they did not have a clue. I am hoping for an upgrade to the firmware.

Incoming faxes do not show time or date


this should print the time and date on the paper

We have a Canon Laser Class 700 series fax machine. When it runs out of paper in cassette tray 1 it doesn't automatically begin to use paper from cassette tray 2. Both cassettes have plain white letter...

Swap cassettes.. The side guides on one of them may not be tight against the paper.

Only put paper in the lower cassette and try to print a journal.

Print out a configuration page or parameter list to see if the machine knows you have two trays.

Tray output

You should configure TRAY 1 as Legal only.
and Tray 2 as plain letter.

Specially when you specify from what tray/paper type to print.

This can be easily configured from the Printer Properties within the Printers and Faxes section of the Control Panel.

Good luck!
