| I have seen the printing slow and showing "error" in the job status before. Copy jobs would run fine, print jobs would print a few, hang, print some more, hang, etc.. It was a problem with their network and the huge excel file they were printing.
But as far as copying slow I would lean toward process control being an issue also.
Once though, I had a similar problem in an NP6085. Customer complained about "running slow", which I couldn't duplicate or fix for a few months. Then I had a intermittent fuser code which turned out to be a crack in one of the ceramic ends on the sub-heater lamp in the fuser (whole other story banging my head against a wall).
I think the lamp also fixed their running slow issue because that went away. I'm guessing that with the high volume they did the fuser temp kept dropping enough to stop the macine to recover, but not enough to throw a code(?). |
