HP LaserJet 4L Error 51

[CassidyHunt]

I just replaced the fusor on my LaserJet 4L. Everytime I go to print now I get an error 51 cycle power.

Can anyone tell me how to fix this?

Have a look at this website:

It gives some reasons for the error 51 on the 4l.
It looks like something isn't seated properly. I would think the fuser kit, being as you have just changed it.
Hope this helps.

I have checked the seating and compared it to another 4L I have. Everything looks to be the same. I found another article online that says the laser isn't getting warm enough. I am wondering if there is a setting to change the warm up time or way to check that.

The laser does'nt get hot, only the fuser.
What made you replace the fuser in the first place?
Error 51 points to a faulty laser assy.

Make sure your laser assembly cable is plugged in. You may have accidentally unplugged it.
