Electrical issues are a common item for Roland when I worked for them a few years back.

As above, electrical sensor problems most of the time, mechanicaly a good press. I suffered with board marking on the run, the second transfer cylinder runs close to the checker plate which you sit on making clearance an issue, always struggled to stop tail edge flapping and bowing.

very capable press but early german electronics gave bad reputation.

Re: Roland 304
I am a rubber roller manufacturer. The Roland 300 series is equipped with oscillating ink form rollers. These rollers use a internal needle bearing and when replacement is necessary the bearings are about $150.. each. (2 per roller, 4 rollers per unit, 32 of these bearings on a 4/c press) In addition to the price of the bearing it is sometimes difficult to obtain them, they are made by only one European manufacturer. I have seen printers replace the oscillating form with standard non oscillating cores.
