just seeing if anyone has had any isues with this new box?

only put a few out, have not been back since install. Seems solid enough.

my understanding,they are running the 552 engines

So, the machine should run fine, but the toner yield wil suck.

I have just one of these out, meter says 30k printed in mono and customer has bought 4 toners + initial toner to get to 30k. has anyone figured out a way to improve yield. firmware is at latest.

new firmware released today . Time to upgrade, and yes, same as 552 engine, and same issues with black dusting

I just had an issue few day ago . 83K missing magenta and yellow colour. Reconected and cleaned developers upgraded firmware and now working fine. Nothing big.
