Question about HP LaserJet 4L Printer

HP LaserJet 4L Manual

HP does not have this on the website. Where can you get a user manual for this printer. I do not need the service and parts information, just the basic info. Seems to me my printer was originally set up with the capabilities of doing remote printing, but perhaps that was so longer ago, I forget. Thanks.

    my Laserjet 4L is a real trooper but lately the roller leaves horrible streaks across the documents, resembling the pre-historic 'wet' fax machine prints.

    Is there a cure?It seems to be part of the cartridge.....

    Hey rswipe, there are only two things it can be cartridge or fuser, no fix on cartridge, guess it would be on cart. it's blade worn out (if marks are same direction as the paper exits) or its drum is light damaged/worn (mark across page 4 times repeated down it)

    To eliminate/verify if fuser needs replacing (ie upper heat roller coating is worn) To check ...stop a print after image(drum) but before the hot bit(fuser), about halfway in, all in the timing, stop it by open cover or power off, then remove cartrige, examine paper under cartridge in machine, if it is stopped correctly image should be present but you can wipe it off with your finger
    (now black :)... if print is good then it is fuser needs to be replaced, otherwise replace the cartridge.

How do I clean my HP Laserjet 4L printer?

There are two ways of cleaning the HP 4L's:
  1. Purchase laser cleaning sheets.
  2. In your user manual there is a section that instructs you to create your own cleaning sheets.
This will clean toner off the transfer roller and the fuser areas. Additional cleaning can be completed with canned air and the specialized cleaning towels also available for purchase. Remove toner cartridge and carefully wipe the interior of any toner or paper debris.


These can leave debris in the printer and contaminate the transfer roller causing very poor quality prints.

A plastic piece broke off and now I can't use the paper tray in my 4L laser printer. Can I buy one??? The printer still works good except now it gets jammed.

The peice your looking to replace sounds like the input paper senor arm. The part is still available for purchase however can be a real bare for the novice to install. The part number is RF5-0601-000CN. The part is available Seattle Platen. Ask for Dale - 888-682-7780. Here's a crude scan of the service manual if you wish to repair the printer on your own. You will be pulling the cover, side motherboard, main base pan and power supply board to get to the flag. Not an easy job but it can be done if your careful.,%204ML,%204P,%204MP%20Service%20Manual.pdf

Hope that helps you. :)

Have a hp laserjet 4l paper jam problem.No paper is jamed inside.Press the reset button,goes through its cycle process. See the D shape roller sensor working,but no paper is being pick-up.Hear a funny...

I have had a similar problem. The 4L has an inherent fault in the motor drive gear. It is made of nylon and has probably developed a hair line crack. As a result the gear slips when the printer starts up and tries to feed paper. I have replaced this part some years ago by replacing the whole motor and gear. I did find the replacement parts on eBay today. Here's the url:

The manual is also on line at another place. But when you order the parts you get a manual on CD. I am not the guy selling the parts but need them too that's how I found them.

Good luck.

HP Laser Jet 4L fuses

The fuses are located on the DC Controller (main bottom board). Getting to the DC Controller Board on a 4L printer is a very significant disassembly. Best left for a pro but if you really want to do it, I have attached below a link to a scanned copy of the service manual. Please keep in mind that the scanned copy is not a nice fresh PDF as most manuals as the 4L was made in 1994 and HP has physically scanned the printed manual for distribution. Just look up the removal and replacement of the DC Controller Board. Once removed, the fuses are glass buss style, readily available at any Radio Shack.

Gotta love that old technology.

Hope this helps you. :),%204ML,%204P,%204MP%20Service%20Manual.pdf
