The printer does not power up when you turn it on. The control panel does not light up and the 'ready' indicator light does not come on.
Power the printer off and do the following:
Note: If the power cord is already connected directly to a wall outlet, try plugging it into a different wall outlet.
If you have installed any type of optional electronic cards into the printer, remove those items. A faulty card can prevent the printer from powering up. Items to look for would include an optional memory card, an optional network card, or DLE options such as a bar code SIMM. Important! Leave the printer powered off when removing any electronic cards or other items from it.
After you have attempted as many of the suggestions above as possible, power on the printer. Check whether the machine makes noise during power on.
