Has anyone ever seen this?

I can't print to the eStudio 230. If I go to the copier, the "PRINT DATA" light will be flashing. Sometime earlier had sent a print job. But checking the copiers front LCD that shows print jobs - it shows nothing.

It's like the printer hangs / crashes.

So I turn off the copier and turn it back on. Then I can print to to it.

Or another example, I noticed the "Print Data" light flashing a week ago. The front LCD showed a print job in SUSPEND. So I deleted it. There were other jobs. But the 'Print Data' still flashed, and my print jobs to the copier would not go through. So I shutdown and restarted the copier. Then I could print.

Mostly we are Mac's (OS X 10.4.11). I don't know if that makes any difference.

Is firmware versionT371SY0U300 the latest for my Toshiba eStudio 230?
Have there been more recent firmware releases that I should be installing that might help?
