Honeywell Reread Delay and Superior Scanning Speed

Barcodes, Inc. was talking to a customer about the Honeywell Xenon 1900’s blistering scanning speed.  We hooked up the scanner and put it in its stand which automatically puts the scanner in presentation mode (scanner scans without a trigger pull).  The customer did what customers do all the time – started passing the same barcode underneath the scanner over and over.  He was not impressed.  The scanner seemed sluggish.

Here is why – Honeywell programs its scanners to pause for 750 ms (this is the default) before the scanner can reread the same barcode.  750 ms – if my math is correct – is ¾ of a second.  This protects against accidental rereads of the same barcode.  It can also be used to keep the scanner from reading codes to fast into an application.

Barcodes, Inc. explained this to the customer and told them to turn off Reread Delay if they really wanted to see the scanner fly.  We explained that the best way to test scanning speed is to put the scanner into a real life environment or scan different barcodes vs the same one over and over.

In the user guides are barcodes that set the reread delay to 500 ms, 750 ms, 1,000 ms and 2,000 ms.  There is even a barcode that allows the user to set their own time.

So why is understanding this so important? It allows your scanner to optimize its scanning speed.
