hello all, we have just had a solution or a workarond, up to now. We have got everything working as it should by using PCL 5 driver instead of PCL 6. We are still monitoring but for the past 2 days we had no more problems. Ricoh are working on PCL 6 for some sort of bug as well as a reason that causes the machine to fall back to printer defauks settings after each print job when using RPCS. Will keep you posted.
