Ingenico IUC285 readers

Discussion created by paulu on Aug 9, 2019

I have the Ingenico IUC 285 card readers and from time to time it ceases to work like it just freezes and a smiley face comes up on screen, unplug the cables from behind the unit, leave for 30 seconds and then re plug and it works again most times. this has been happening for over 12 months. happens for a week or two then nothing on different units no patterns, any thoughts
