Most likely either a faulty Cyan or Yellow toner. Pull those 2 cartridges out and flip them over to inspect the drums on the bottom of the toner. Metallic drum should be fairly clean; see if you...
I'm guessing you have the LaserJet 5L & LaserJet 6L? Those you might as well recycle.
There was a plain "LaserJet 5" (no "L" designation) that has an MIO slot where you can install an HP JetDirect...
"Refurbished" feeders won't contain new rollers -- they will either be lightly-used feeders that are "cleaned up" or the feeders were rebuilt by harvesting decent parts from other broken feeders. ...
Definitely sounds like a timing issue; the second-stage of the duplexing is somehow entering the path too early and zipping past the toner cartridges before they can lay down a print. I would try...
Sounds like 2 bad toner cartridges in a row. Old stock HP cartridges are prone to failure just sitting on the shelf ; some of them are 15+ years old.
It's difficult to find a good quality cartridge...
If you want to post a photo of the defect it might help.
Normally we would blame light print on faulty toner cartridges; if the cartridges are aftermarket brand then I could see 2 sets in a row...
Sounds like the onboard Ethernet connection is starting to fail. That is part of the formatter which is the main system board. You could order another formatter board, here's a link....
That error code is pretty specific, something is wrong with the Yellow laser scanner error. Either you are not replacing the correct laser scanner or there is a problem with the ones you are...
If you don't want to replace the whole system, you could just try a different fuser and see if it works better with your envelopes --...
Sounds like something is wrong with the fuser not turning ... what model printer is this? My first instinct is something may be wrong with the fuser you just installed and you might need a warranty...
The key is to observe the pickup rollers during failure -- if the rollers are touching the paper and spinning but the paper is not moving, I would replace those rollers as they are losing grip. These...
Two questions --
1. Is this printer connected via USB?
2. Are you for some reason disconnecting the USB cable occasionally?
If you are disconnecting the USB cable occasionally, you should...
If you have the 4050N model (not the 4050TN) it doesn't involve a full disassembly, just a little access panel inside the paper tray cavity. Here's a link to accessing that PCA board --...
That sounds like the transfer belt assembly is failing / not cleaning properly; it is a consumable part so should be something you can change yourself, it is located just below the fuser assembly. ...
Since you've already changed the Magenta (pink) toner, I suspect the Magenta drum unit is failing. We carry replacement drum units at PrinterTechs (866-352-7108).
There is no documentation available for these kinds of individual board-level components. HP intended for faulty boards to be replaced rather than repaired so you really can't find pin-out...
There is a solenoid that can get gummy/sticky with time, for Tray 2, that will stick during pickup and cause an extra sheet to feed. It's involved to access it, you have to remove covers &...
Sounds like the formatter assembly is failing; the formatter assembly is the main logic board and is a common failure part on this model. Replacing the formatter is not difficult, here is a link to...
My guess is the noise is probably coming from a faulty toner cartridge , that's the most common issue. If replacing the toner cartridge doesn't help, it could possibly be the laser scanner but it's...
Sounds like a sticking solenoid ; over time the sound dampening pad gets "gummy" and causes the solenoid to stick intermittently. On this model it is a big job to disassemble and access the...
If the roller isn't spinning (you can watch it when you fold down the manual feed tray) then yes, something is off with either the solenoid or the drive mechanism for manual feed roller. Solenoids...
You mention fading up the center when copying; do prints from your PC or internal test pages from the printer show the same fading? If this only happens with copies, then you should clean the glass...
Can't post pricing here but will PM you.
Unfortunately that motor just isn't available individually -- we (PrinterTechs) do carry the entire paper pickup assemblies (RG5-6208).
