    Hmm i changed battery my self today, and just booted it with that power off receipt feed system. I tryed to enter 21151 code after it, but it didnt work. Is that MAC code what you ment?

    Do you have any idea whats mac code in finland? Im trying to google it, but cant really find.

    We have year/month/day systemif it helps btw

  • sabo104 Mar 05, 2009

    It gives e04 when i put MAC code and enter subtotal, same with every code and another push in subtotal will do "something". But when i try to set date to correct, it still says 09 error. Should it give that 04 error after first subtotal push? And yes i have clerk buttons.

  • sabo104 Mar 05, 2009

    I checked the old receipts and last date was 21-08-04, so i guess its day/month/year afterall, even finnish usersguide says year/month/day.

Hi. It means the password has not been entered. I suspect this machine has not been RAM cleared properly after the battery was changed. What MAC code did you enter when you changed the battery and initialised it?

    Yes. You must RAM clear the machine. Do the initialise procedure using journal feed, then enter the code depending upon your country and setup needs using the init table.

    In that case, you will have a non standard MAC code since your date system is so rare. The two standard MAC codes are 21000 for Clerks by push button, or 21001 for clerks by PIN number entry. However, that will give you our dating system which is DDMMYY, so try changing the first two digits until you get the date to work correctly. I think you will need a 0 first, so try 01000 or 02000 or 03000 or 04000 or 05000 for clerks by button. If you have no clerk buttons you will need to add a 1 on the end.

    Great. Then our codes should work perfectly. Just choose the clerk type that you are using then try 21000 or 21001

    E 04 means wrong MAC code. If you get the MAc code right, it will print out.

    This is the whole procedure:

    Turn key to Program mode.
    Turn power off at wall.
    Hold JOURNAL FEED button down while turning power on at wall.
    You should see "0000000000" or "LLLLLLLLLL" on display.
    Type 21000
    Press SUBTOTAL
    Wait for print.
    Turn back to REG and make sure a clerk button is pressed down.

    Try it again and see if this works.

    You are still only doing a half clear. You must hold JOURNAL FEED, not RECEIPT FEED.

Casio TE 400F error 101 plu maintenance file full and Error 105 PLU file full.. I can't figure out how to: delete any plu's - clear either of the errors - change any other items Any help?

I haven't worked on these in a few years. Normally your dealer would give a training session as scanning is the most complicated setup on a register. As I remember, it is part of the direct maintenance programming for scanning PLUs. Also, check the amount of scanning PLUs you have allocated. The dealer would normally supply backup software such as Casio CV when you bought it so you don't lose all of your PLUs when files become full or corrupted. There is a site which has the dealer type manual. If you don't have it, you won't have all of the scanning codes:
Hope this helps.

It is locked and a code that is eo1 is on the screen it is the casio 3700

It simply means you started a sequence then tried to use another mode without finishing the sequence. Turn the key to each mode until the error stops. That is the mode you were last in and you must finish what you started in that mode before you turn the key again.
