[Koha] Barcode reader is unable to read less than 3 characters

Hello, I have installed Koha on and did entry of near about 1K books. Also generate barcode for tthese books. Books barcode starts from number 1. When I took print and read the barcode from barcode reader, I found that if barcode is less than 4 characters, barcode reader generate no results. It is working fine if the barcode is greater than 1000. Please let me know how can I fix the issue? re-updating of 1000 is lot of manually work? -- Thanks, Laxmilal Menaria | +91 982 955 3793 | http://laxmilalmenaria.com/
