Re: no display and no connectivity to the computer
Replace all electrolytic capacitors in power supply section on mainboard. caused by poor quality lower voltage caps being used in powersupply. Problem will reoccur every 2 to 3 years if 105oC caps are not used. If mainboard is replaced with new mainboard problem will reoccur within same timeframe. Fix old mainboard using higher voltage and higher temp caps and problem will be gone for good.

Have you installed a new toner??? It may take a few minutes for the copier to add enough toner to make a copy. It's been awhile scince I've worked on one... But I think if you turn it off and hold down the Clear/Stop botton when you turn it back on, it will make the copier add toner... It looks like the display i chashing a box in the display. Good Luck

TO RESET THE MACINE PRESS THE ORANGE BOTTON (C),PRESS THE BOTTON UNDER THE AUTO DENSITY LIGHT,RETURN TO THE FIRST ORANGE BOTTON THEN THE AUTO DENSITY BOTTON, YOU HAVE TO BE FAST WHEN PRESSING THE BOTTONS, ALL THE LIGHT ON THE DISPLAY WILL GO OFF THEN PRESS 14 AND PRESS THE GREEN PRINT BOTTON,THE MACHINE WILL RESET AND START TO WORK, BUT IF THE PROBLEM COUNTNUE CHANGE THE FUSER UNIT.

2. Press and hold the power button of the printer.Wait for 30 seconds.
3. While holding the power button, re-plug the power cable.

Hit the yellow botton ( Reset/ CA), then 1 then 0 then7 , then hold down the (Stop) botton till the display changes... Then turn the copier "OFF" then "ON" it may clear the code. The code has to do with your fixing unit.
