Tip & How-To about Casio Parts Cash Register PC Desktop

Cash register storage - IMPORTANT

Are you going to store your cash register away for a while? Then beware! Most machines have an internal backup battery that stays charged when the register is plugged in. When you unplug the machine, or you have a power cut, the registers memory (all of your products, store name, keyboard functions, files, and other system settings) are held via the battery. If you leave the machine turned off for more than 1 to 2 months, most registers will lose all programming, and you have a big job on your hands. (If it is dead, or has scrambled looking characters when you plug it back in, then data loss is likely).

What you need to do is take it out periodically, and plug it in (make sure the display is lit). I recommend leaving it on for 1 day each month to keep the battery topped up. If you haven't had the battery changed within the last three years, that is a good idea too, as they lose their capacity over time. If you have an older battery in your machine, then charge it more often, say once per week.

If you have any questions regarding the batteries, please just post a message in this forum.

how to reboot


I seem to recall there isn't really a reboot. If you are looking to change the system over to reflect your business and products a couple of tips are in store.

There is an internal battery and when it becomes weak it will cause a lot problems. I'd check the date on the internal battery and replace it if it is out of service life. Simply calling a local battery shop will usually get you a normal expectation for the life of the battery and also using your favorite search engine will find the same. The battery doesn't cost much but is very important to keeping your sanity.

Back to your reboot - I can say the best way to approach this register is to go through the manual which is located at the link below.

Best wishes,

my sharp ER_3100 wont operate it shows 00000000

The ER-3100 has a memory-protection battery soldered to the main board. It charges whenever the register is on, and when the register is off, it can hold the totals and programming for over a month.
But the ER-3100 is about 20 years old, and you battery has lost its ability to hold a charge. You need to have the battery replaced and the entire machine's memory cleared, then programmed. Don't do it. You need a new cash register. All the replacement machines are much cheaper, much faster, and much quieter than your old ER-3100.

tk 6000

The machine has lost all programming due to the back up internal battery going flat. It will have to be RAM cleared. Then all programming performed (including system programming). If you have the software, or your dealer does, then you may have a backup. Otherwise it could be hours of work.
I can give you basic pointers on getting the machine going if you have no backup, then you can decide how much extra you want to do.
