You may did not try in the right way! The access code (5454) is 100% right for 347002K/347112K and 34700Z new series machines. If keypad has oil injection button (old series machine) press 8787 on keypad.
However you can try as following: To access the change Defaults menu press 5454 (If keypad has oil injection button old series machine press 8787) on the keypad then press ENTER/START arrow key. Now display will change to "Calibrate Scale". Press up or down key to select option you wish to access from: Set Tank Tare, Output Test, Input Test, Keypad Test. Prepare to Ship. Reset Board Memory etc...

NOTE: DO NOT CHANGE 'SET TANK TARE' OR PRESS 'PREAPARE TO SHIP' & RESET BOARD MEMORY' IF YOU ARE NOT FAMILIAR WITH THIS MACHIN!

Hope this will help you. Good luck!

Try this. We are Brother authorized.

It's a "configuration" option.

But, there are "diminishing returns" -- adding more seeds won't make your downloads any faster.

Compare it to a 4-lane highway -- when there's the "right" amount of traffic, all 4 lanes move quickly.
When there is "too-many" vehicles, traffic slows down, even though the width of the highway (equivalently, the speed of your Internet connection) has not changed.
