Hi fhannan,
Thank you for using the Support Forum. Please take a look at the informtion about paper and printing issues on the Iridesse. The paper weight or type could be part of the issue. Please consider contacting your support centre for further assistance.
Since the long paper option/white ink has been installed, I've had to have the Back Up Roller (BUR) replaced twice. At first it seemed to be caused by running a 'foil' paper through with some kind of back charge from the paper. This last time, I haven't run any 'objectionable' paper in the duration of the roller. My CSE found one other instance in the UK. The question is....is this an inherent problem with the diodes that are being used to buffer the power to the roller, or is something else going on? Will there be adjustments done to aleviate this issue, or am I going to have to have it replaced every 125,000 impressions.
