Question about HP LaserJet 2840 Printer
Every so often the machine gets stubborn and simply doesn't do anything when I push the 'copy' button. I have to turn the machine off and on again, then it goes through this whole 'calibrating...' routine and then it works again. Any ideas?
Do a manual calibration from printer display (yes, on printer)
3-4times without pause between. That should solve it! It means something is out of sync. Worked for me.

Hey there. Try Up-grading the firmware (U can check if is the latest by printing a config page). Other things to do - replace the USB cable (if U're using it locally) - the USB cable must have under 1.8 m and should be shiended otherwise should have filters on each end.
