Sharp ER-A310 Cash Register Programming Help and Tips
Sharp Cash Register program very much like most commercial cash registers do. You should always plan out your
program before you just start programming the register on the fly. Write it down and often even write out your code
before you start plugging in the register. You will be surprised how much faster it will go and with less trouble.
                   Sharp ER-A310 Cash Register Tax Programming

To Set the Tax Rate (I only deal with Rates and not Tax Tables, most states can use rates and do not require
tables, however if unsure please check with your accountant, CPA, Dept. of Revenue)

  • Page 46 in the manual
  • Turn key to PGM (program)
  • Enter 2711
  • Press the Decimal Key
  • Press @/For
  • Enter 1 (to select tax rate 1)*
  • Press @/For
  • Enter Rate 0.0001 to 99.9999% (example for 8.8% enter 8.8000)
  • Press @/For
  • Enter Lowest Taxable Amount which in most places is 1
  • Press the CA/AT (Cash Key)
  • Make sure you return the key to Reg.
  • Perform a Test.
  • Please remember this sets the Tax Rate it does not make the department taxable (see next step)

*To enter tax rates 2 through 4 replace 1 with the rate you wish to program.
My preference is to program Sharp Cash Registers using the Job-Code Based Programming rather then the direct
method also available in some models. Everything on the page will be Job-Code Based Only.

Notes: you can make a department taxable by multiple tax rates for example to make a department taxable by rates 1

This does not make a department open or preset

This code assumes a plus department not a minus

There is more to this program although those feature are very seldom used. In this example I left the Validation print
Non Compulsory, Normal Sales departments, and Normal vs. Hash.

This program does not set a price, only makes it available or not.
