Question about HP LaserJet 4 plus Printer

1 Answer

HP LaserJet 4 will not power up. For several months, it has been taking longer and longer to power up. Flip the switch and nothing happens for minutes, then it cycles on. Now, nothing. No lights, no hum, no power on. I changed the power cord. No effect.

Hello,

The AC Power supply in your printer is out. The laserjet 4 and 4+ printers would both have long power up times when the power supply would start to die. You can get a replacement power supply very cheap now since the printers are older. We have them in stock as pulls from parts printers that should work just fine for you. We sell them for $30 plus shipping. We also have service manuals available if you need one. Let me know if you need more help.

HP LaserJet 4L quit working It's connected to my PC and it's on. All 4 lights are on; 2 green and 2 orange. When I try to print, the paper goes through but nothing is printed on the paper.


Empty cartridge maybe?
Otherwise it's simple: selt-test page(by printer button) printed ok - it's outer problem. Self-page is blank - it's inner problem. And so on... use Golden Section method

My machine won't turn on when I flip the switch. It is properly connected, I tried it in several outlets - that are working for other appliances and I am left baffled. I haven't used it in about 6...


do you have user's manual with wiring diagram? if not try H.B. If you get one, there is a diode that keeps your machine from frying from over-voltage. Kinda like a fuse, but is not a fuse. If you can check voltage across it, it is not the diode. That is a simple start and the most common problem for not starting.

SONY RDR-HX950 is showing WELCOME in display at startup, nothing else happends


i have a sony HXD-1065 which was doing exactly the same thing.
i searched loads of forums to get some idea of the cause but nothing.
to cut a long story short, i put the recorder away in a cupboard for approx 4 months then just as i was about to list it on ebay as faulty i thought i'd just switch it on and see what happens and it came on and loaded up as it should with no problem so i unplugged it and plugged it back in several times to see if the permanent welcome message came back but it just loaded and has worked perfect for the last 5 or 6 months.
i found out later that the memory capacitor needs to fully discharge before it can reset itself on power-up.
i'm not sure exactly how long this takes but it took me 4 months to find it works again.

My HP Laserjet 4 will power up and print beautifully for about 5 minutes, then it shuts down - all lights go out, no fans working - nothing - dead! I have to turn the power switch off and wait several...


Have you powered-off the printer, unplugged the AC power, and used a can of compressed-air to give the printer a "blow-job" ?

A layer of dust will act as a layer of insulation, causing the printer to overheat, instead of "radiating" the heat.

I have an HP laserjet 4 printer and suddenly it just turned off.


If it won't turn on, the power supply is dead. Time to bury it, I'm sorry to say.

1-the switch is bad, or not engaging properly
2-the power board is bad/ bad transformer
3-bad socket

get a portable lamp plug in socket and wiggle totest connection, if it stays on the socket is good otherwise call electrician.
leave printer on for a few minutes does it come on by itself witout you getting jiggy with it? bad board

if not the switch is most likely the problem

HP Laserjet 3050 No paper pickup


My printer now spits out the paper all over the place and jams up all the time. Did not happen when I first got my 3050 a few months ago.

Adding memory to laserjet 4


flip open the top cover, and look on the top of the right side cover, there is a latch,
push it down to release the side cover, and pop the back of the right side cover off, the side cover will flop down. You'll see a large metal access door with two screws, take out the screws and open the door, and you'll see the memory card slots.
Good luck!
