All the lights keep flashing --won't print!

Push the print button that keeps flashing and search for job reset. Cancel all. Hopefully that works!

Sounds like a bad print job stuck in a print spooler.
Turn off copier. Go around to all computers that print to it and open the print queue. delete all print jobs. reboot each PC. Power up copier and see if it clears

This just happened to me! I found this fixya and it didn't help me. So I checked the status of the printer and it was trying to print some 3,000 envelopes, OOPS!!! Needless to say I cancelled the job but it still had to go through all of the pages before cancelling and finally stopped blinking!

First, turn off the printer.

Then, remove/delete all print jobs, if any (printer icon tray > show active printers > select jobs and press delete). If the jobs didnt get exclude and are keeping the status of "excluding/deleting", restart your windows.

After reboot, check if the jobs are gone. If so, turn on your printer and try to print again.

I hope this will help you :)
