HP LaserJet: Why is toner leaking when printing with my HP4?

Tue, 17 Mar 2026 12:30:28 -0700

I’ve used this printer forever. Recently I replaced the toner cartridge and now the toner leaks all over the inside of the printer. Pages come out totally black. I’ve vaccummed the inside, tried another cartridge, but the problem continues. Any ideas?

HP LaserJet CM1415fnw: New cartridge does not work - transport lock

Thu, 05 Mar 2026 02:08:20 -0700

I have this old, but decent printer and my ink was almost out. So I took a new cartridge (I have 2 originals stil in closed package) and removed the orange transport locks and shuffled the cartridge.
After putting it in, I get the error remove transport lock (or shipping locks, I don't know the exact word, my printer has Dutch language).
And I can't figure out what I can do to fix this. I swapped the chips from the old and the new, same result. And the old still works, but very bad prints since ink is almost out. I tried the other new one, same result.
Any ideas?

LaserJet Pro 400 M401: Duplexing jams every time

Tue, 27 Jan 2026 10:25:02 -0700

I have about 70 of these HP M401dn printers in K12 classrooms. Most of them are tanks and just keep going. But I have about 5 of them (and growing) that jam every time the user attempts to duplex. It SEEMS like this was caused by trying to duplex 120lb card stock; I was probably the first to try it and "break" my printer but I've had others repeat the mistake.

I don't want to give up on these printers. How do I stop the duplexed prints from jamming?

HP LaserJet 1020: HP LaserJet 1020 roller identification and replacement

Mon, 26 Jan 2026 13:46:49 -0700

This roller inside my HP LaserJet 1020 has worn out, and printed pages have defects in correspondence of the roller wear.

Does anyone know the part's name and/or a part number so that I can find it? Maybe there also are some repair/disassembly instructions?

HP LaserJet: My HP LaserJet 1010 printer keeps the paper roller running when it is

Wed, 07 Jan 2026 20:24:34 -0700

My HP LaserJet 1010 printer's paper feed roller keeps spinning when I turn it on. If I turn the printer off and then back on, it works normally and does not show any device error. I don't know what is causing the problem or how to repair it.

HP laserjet 4L: Why is my page smeared black after a paper jam in a laserjet 4L

Fri, 26 Dec 2025 03:45:21 -0700

An HP LaserJet 4L had a paper jam which was cleared by pulling out the sheet by the owner. Subsequent sheets however showed irregular variable black horizontal smudges with the test page text only just visible. A new cartridge didn't help.

I have taken the printer to pieces and cleaned surfaces and contacts, replaced 4 capacitors on the dc controller PCA (high esr), but the problem persists. Similar results with engine test.

Other things I have tried:

Removing the 45deg mirror to show that it was the laser causing the blackness. Yes, it did remove the blackness, but putting the mirror back did not bring back the blackness until a day or so later ( I did try to keep everything as dark as possible).

Another inconsistency was that after a rest of several hours, I found the text of the test page was not initially visible within the blackness, but was visible on the second and subsequent attempts.

Also noticed that the text repeats itself at 75mm (circumference of drum?) suggesting the image on the drum is not being erased.

My assumption is that it's the high voltage power supply that is failing and giving inconsistent results and has nothing to do with the original paper jam. How do I repair the HVPS, as I can't buy a new one.

Images show my printout and what it should look like.
