HP Laserjet 4L , no power by geno (9/7/04 5:33 PM) reply + / -
My hewlett packard laserjet 4L has none of the four lights illuminating and I can't get a print out of it. The power cord does have power to it (checked with an ohm meter). I tried to find another reset button but couldn't. Nothing in the manual as well.

If it's totally dead, then it would be the controller board. There are a couple of 3ag fuses on it, but it's never that simple. To get the board out, you have to remove the case, the fuser assy. and the formatter board off of the side. Then there's about 7 or 8 screws holding the board on the bottom of the printer. There are also 2 ground straps under the formatter that have screws holding the board.

Read the thread on the 4L Controller board. I've had this printer for over eight years and love it. There's power to the printer but no led lights. I probably need a contoller board if you have any. Anything else you think I might check would be helpful.

DO you think the controller board could be my problem. It is an older printer that worked great, until I changed the toner cartiage and try to fix a paper jam. Once the paper jam was removed it would no longer power up. Can anyone help?
Thanks in Advance

My 4L died recently, too. I was thinking the power supply. Is it worth getting a new controller board? It's got to be 10 years old. (Toner cartridges cost $70 now! But I still have a spare one!)
Thanks for any info.

My printer stopped working when the electricity went out for an hour. Can anything be done for it?

I am requesting info on the power supply board mentioned. Do you have a working one for me?
What is the warranty?
How much does it cost?
What sipping do you use?

My 4L has no power ever since I fixed the last paper jam. If you know of an available power supply/controller board, please let me know the details. thanks much.
