Hello. Just disovered this wonderful forum.
I have several of the old, ancient, original Laserjets. In fact, I have several just for parts. I refuse to use any other printer, as these cost nothing and run forever.
I am fairly good mechnically and want to learn to fix these myself.
I have one right now that is not printing correctly. I assume it would be best for me to post a photo or two, correct?
Thank You!
Fred

Yes, HP Laserjet 4 Plus is a great printer but its cartridge maybe not so easy to buy from and if its power is bad it will be a problem to find a good one.
Still don't know what your problem is ?
Is there any error message on the LED panel?
