Question about Casio QT 6000 Point of Sale Terminal

3 Answers

I've bought a casio QT2100 second hand and was trying to reset it

Based on the info that i've got from but i was stuck with the operator mistake error message. Firstly, i've manage to get to the selection screen (Flag clear and init 2). Then when i pressed any buttons including yes button the ''operator mistake'' error keeps coming back.

I've also noticed that before i reached the menu, it displayed a network error message and 3 times beep sound.

Just wondering, is the machine faulty? Do I need to hook the receipt printer, cash drawer, or any PC to be able to use it?

Any help will be greatly appreciated.

    Regarding the QT2100 register machine. I bought it second hand and wondering if i need a PC to be able to use the machine. If yes which software do i need to download to reprogram the machine.

    Secondly, which RAM slot did you mean? The ones on the motherboard of QT2100?

Three beeps usually denotes a RAM problem in your system. Try re-inserting your RAM again into the slots properly.

Easy. that machine was in a network of other ones like it or the IPL is corrupted, or is in need of a MAC. A mAC will clear all info and it will need to be reprogrammed

    Basically at this time the program is most likely corrupted. When you MAC the register it WILL lose ALL ifnormation other than date and time. to use this machine you WILL want a printer and a drawer/base. Then if you can find a Casio dealer in the area you can get them to reprogram the machine. the procedure goes as this

    1 turn the machine off underneath on the right side toward the rear of the machine.
    2 Hold down the upper left hand button and, switch it on, wait for the screen to reappear.
    3 Enter 20000 and press the subtotal button.( third up lower right hand corner and one in)

    The machine will go through all kinds of funny stuff like a flag clear and then ask to be signed on.
    I guarantee at this point all programing is back to default

Why do you need to master reset it? You will have a large amount of work to re-program it if you do. If you are serious about it, you are going to need the programming manual so you can set the memory and machine features during the initialisation as it is not straight forward to reset a powerful machine such as this. this manual will guide you through the master reset process and then you need to follow all of the tables for setting up:

All the lights are on: power light, lamp light and temp light... How can I fix it?

If you have the manual you can look at the back for troubleshooting. The problem or solution will depend on if the lights are blinking and what color they are. The manual can be found here. You will want the basic operations manual.

I just had a XJ- S41 projector in for repair because it wouldn't power on. The power light was red solid but the temp and lamp lights were blinking red. Apparently a reset was needed, but I was told it was an internal reset that had to be done be a technician. I'm dubious of this info as I've seen some reset procedures listed on this site that may have worked, but I can't confirm as I sent it in. It cost $45 plus shipping to have Casio do this reset and there was nothing wrong with the projector or any parts replaced. Casio wouldn't tell me exactly what reset procedure was done and they will not let you speak with a technician or even try and get more info for you. Using their online repair service though was easy and swift. Just go to

Need to know how to operate Cartier Tank Francaise Chronography W

The top button is for chronograph function and puts the chronograph seconds hand in motion. The bottom button is for resetting chronograph seconds hand to zero.
Do as follows:
1) push the top button once- seconds hand starts moving,
2) push the top button once more- seconds hand stops,
3) push the bottom button once- seconds hand returns to zero.
You can repeat as many times as you like- seconds hand will allways start the countdown from zero.
Depending on what movement your watch has(mechanical or quartz), there can be more variations, but the basics are as described.
If you need more info, supply full info of your watch(make, model, numbers, etc.), please.
Do not forget to rate, please.
