If the braille is not correct on a printer it can be the consequence of new firmware, faulty adjustment, hammer batch etc. It can be adjusted in "protected service". This functions are designed to be used by Index distributors, who can get the pin code used for accessing the "protected service" menu from support@indexbraille.com.
