Question about Panasonic FP-7735 Black and White Copier

1 Answer

Panasonic FP-7735 won't recognize paper tray

I know - we need to get rid of this machine.

Main paper tray is not recognized by the machine. It is there, it has paper, and yet the machine does not see it.

    Must have been the gremlins-the machine acts as of that tray is not even there (even in manual mode).

    BUT - the instructiosn above must be for a slighty different machine:

    No "Function" button on this one.

    Original Size: there are 4 buttons (Ledger, Legal, Letter, & Invoice)

    Sounds like this is what I need to do - get into the Function mode, but need a different key combination!

  • jakeami Jan 25, 2008


    I was able to get into the function menu and make the change, but I can't get out of the function menu!! Even turning off the machine, waiting a few minutes, and turning it back on doesn't work.

    I tried "User Preset + Orginal Size (ledger) +3" and that doesn't work. No individual key seems to work.

    I had trouble getting out of Functtion mode - but finally found a key combination that worked.

    Still no luck - I changed F5-14 from 1 to 4 and it still doesn't see it.


    F5-14=4 Letter-landscape orientation installed

    F5-15=1 Letter-regular orientation installed

    F5-16=0 Legal tray installed

    F5-17=0 (no tray installed)

    F5-18=0 (no tray installed)

    Is it possible that F5-14 through 18 are the wrong place for the tray settings? I say that only because F4-14=4 didn't change anything AND because F5-16=0 is working fine with legal even though it appears the setting should be F5-16=2.

    Also - now the copies all have dark blotchy areas all over. Not sure if I accidentally changed other setting(s) while I was trying to deal with the paper tray issue.

  • jakeami Jan 25, 2008

    I got that figured out (finally) - see my additional comments above. The paper tray is still "invisible".

Can you hear the tray rise when you close it? Is there a red, blinking "out of paper" light on the control panel? Can you select the tray manually?

Or, you had a power outtage, or gremlins, and the settings reset itself, you can go in to service mode and set the trays up again.

Hold the following keys to fire up Function mode. "Function + Original Size + 3". Hit 5 for F5 mode. F5-14 is tray 1. If you have a duplex(ADU) unit installed, you'll want to check out tray 2. F5-14 is tray 1, F5-15 is tray 2 all the way down to F5-18.

Key in whichever number you need.
0: none (no tray installed)
1: Ledger
2: Legal
3: Letter
4: Letter-R (landscape)
5: Invoice

    You want to use the "Original Size" top, left button (Ledger). I didn't mean function, I meant User Preset. It's Function on the newer ones.

    So it's User Preset + Original Size (ledger) + 3

    User Preset + Clear will get you out of service mode.

    If that's the case, you'll need a tech to come out and look at it. Those machines can be erratic for no reason. And the nasty looking copies could be any number of things.

That could be a few things. Your corona wires might need replacing. Something with the middle transport section, where one of the corona assemblies is at, is not making contact properly. Or it could be the high voltage power supply.
