Question about HP LaserJet 4L Printer

1 Answer

Printer is not working.

The printer is making a loud cranking noise when I turn it on. I went ahead and replaced the toner cartridge, but I still get the same noise. The noise seems to be coming from the front left hand corner.

Re: Printer is not working.

There are several things in the front that could be making that noise.The transfer roller,paper guide/top ublique roller and front obligue roller which is on the left side front. It is hard to say. I guess the printer is printing OK. If not what is the printer doing? Do you get any paper jams? Printing light? Can you rub the print off the paper? Any labels stuck? Please answer questions so I can help you. My guess is a roller problem. Which one is hard to say since I can't hear the printer myself.

Clicking noise

Check the printer thoroughly for any small pieces of paper caught on a roller in the printer. If your printer is making a grinding noise, you may have a loose gear or roller in the printer.

If the noises started shortly after you installed a toner cartridge, turn off the printer and pull out this toner cartridge. Look up into the printer where this toner went. Make sure that both the charge roller and the transfer roller are still seated in the printer properly.

  • The charge roller is a tan-colored or gray roller attached to the inside of your top lid. Remove the toner cartridge from your printer. Close the top lid halfway with the cartridge still out. You will see the charge roller come down as you lower the top lid. Make sure that the charge roller is installed correctly within the two black arms on each end and that the roller does spin freely.

  • The transfer roller is the black, spongy roller in the bottom of the printer, under the toner cartridge. Push lightly down on it at both ends to make sure it is seated properly in its housing. NOTE: Try not to touch the charge roller with your bare hands. It is susceptible to the oil and may cause a permanent fingerprint to remain on the roller surface.

  • When you have checked the charge roller and the transfer roller, look around inside the printer. See if you can find any rollers that look loose or broken inside. Also look for any loose shreds of paper. If you do find a loose or broken part, you printer will probably require service to fix the problem.

If the rollers look fine, go ahead and reinstall the toner cartridge. If the squeaking/grinding noise continues and none of the rollers looks out of place, try swapping out the toner cartridge. There is a small chance that the toner cartridge is causing the squeaking/grinding noise. If you have any extra toner cartridges in stock, try another toner cartridge and see if that clears up the noise. If you have another working printer of the same model, try swapping the toner cartridges. See if the problem follows the toner cartridge or stays with the printer.
If replacing the cartridge does not cause the noises to go away, there are a few other things you can do to help pinpoint the source of the noise.

If the noise continues on the main printer, try opening the rear exit door while printing. See if you can tell if the grinding noise might be coming from one of those rear exit rollers/gears. If it does sound like it is coming from the rear of the printer, again look for any loose or broken part or any small pieces of paper.

If you have added any additional feed options (like a tray 2 or 3 option, duplex option, or envelope feeder), please remove these options. Try printing a few prints without these feed options attached. This will eliminate one of the feed options as the cause. If the noise goes away when you remove the options, reattach them one at a time. If the noise returns on one specific option, a roller or gear on that option may be the cause of the noise.

Is your printer making a rhythmic THUMP - THUMP - THUMP - THUMP noise when printing? This noise is a side-effect of a feature called Envelope Enhance. The Envelope Enhance feature is built into the fuser unit of the printer to help keep envelopes from wrinkling. This sound is perfectly safe and normal if the printer is printing on envelopes.

If none of the above fixes eliminates the noise, the printer will probably need service to return it to working condition.

Yesterday while I was printing on my HP Laserjet 4, it started making a loud clicking noise, and jammed. I opened the printer, looked at the gears on the right behind the toner cartridge and I can't see...

The clicking sound usually indicates a broken fixing coupler gear. The is the little gear on the top left side behind the fuser unit in the printer. You can replace it your self to save on a service call. The part number is RF5-0350 and it is available here:

Hard to tell without hearing it. But, if it is doing it all the time it is turned on but not in use most of the time that would be a fan making the noise. The other suspect would be a fault toner cartridge or the fuser. you may need to have a tech look at this.
Hope that helps...

Loud clicking sound

We had the same problem, with a slightly different solution... it turned out in our case that the new toner cartridge's internal drum was too stiff, so the printer was trying to turn the toner spindle and failing, resulting in the clicking noise. Our solution was to manually turn the black center gear by hand a few times, and in doing so loosen the drum up a little, so that the printer could turn it. We put it back into the printer, and voila! No more clicking noise.
Thanks to whitehorse1 for his (or her) solution... though it wasn't the exact same problem for us, it was what put us on the right track. :)

Makes loud sounds

I had the same problem with the loud grinding sound. The gears on the cartridge(s) is not turning but rather stripping creating a grinding sound. Reinstall all of the toner cartridges. If that doesn't work, pull each cartridge out and manually turn the gear on the cartridge. If the problem persists, you may need to purchase a new toner cartridge.

Loud clicking noise

Power the machine on with drum and toner removed, check for noise....

It will be either the Fuser, Toner or the drum.

If it is non gen. or refill toner, fault found.

The drum is a normal consumable that you change every 3 to 4 toner cartridges, so if any of you have used more than 4 toners and havent changed the drum, I'd say that we have found your problem. to the hangers on .....

Fuser, thats the hot bit at the back, these have a gear that cracks because the whole fuser assemble is old, brittle and stiff, you can pull it all apart and change the gear and be off, but soon it will more than likely break again, I know cause if I do that as the fix they come back within 6mnts.

Replace fuser, or have it replaced

Fuser is a HiVolt, HiTemp part. Caution!!!!

Loud clattering noise

-Open the Front Cover. -Remove the Toner Cartridge -Remove the Drum Cartridge -Next locate the black gear attached to the end of the Drum and turn it with your fingers. -Check to see if the gear is locked, or difficult to turn. The gear will only turn in one direction. -If the gear won't turn at all, or if it catches while you are turning it, or if you hear the same noise when you turn the gear that you heard when the machine was on, the Drum Cartridge is the cause and will need to be replaced.
