HP Laserjet P2015 Error Lights (LED’s) Stuck On

last week, I had an HP Laserjet P2015 with a extreme attitude problem. The pinnacle  LED’s (Paper Jam and Toner) had been caught on. it's far regular for the lighting fixtures to illuminate once you first flip the printer on, but after some seconds they must be replaced by way of just the prepared light after the printer has completed its boot system. This one in no way finished booting. a few instances the paper light would be the only one on. I recognize you don’t need pics, but whats up, i have them. The state of affairs gave the look of this:

I stored trying to find the jam, commencing covers and powering it on and stale. as soon as i used to be completed with the physical and verbal abuse, I observed that the motor was running in brief after powering on, as it generally does during the startup process. The motor will not run if a jam is detected via the sensors (move beforehand, stick a sheet of paper in a sensor and notice!) This have to mean the problem isn’t a jam right?

So what’s the deal?

short solution: The formatter board.

long solution: there is an IC at the board that makes use of a BGA form aspect. As with many similar chips, mainly early designs it appears, the failure is probable an open circuit due to a ruin in one of the solder balls from repeated thermal pressure.

If it’s horrific enough, the pc will not even understand that there may be a printer plugged in, although I’ve visible exclusive combos of the above symptoms.

So, you’re questioning how you could repair yours? nicely, after you’ve decided that that is indeed your problem, the following step is quite simple: you need to get to the formatted board. To do that, pull out the paper tray and toner cartridge. Then, firmly draw close the printers’ bottom left corner and pull again and outward to launch it, repeating for the pinnacle left corner. it may help in case you place the printer right aspect down on the desk and do it like this:


If a picture is worth a thousand words, that video must at least be worth a $1.50.

as soon as the side panel is off, you can see the formatter board. in case you appearance down at it from the pinnacle aspect, you may even see the little balls of solder under the IC.

You’ll want to split the board from the printer chassis. begin with the aid of unplugging the cables, cautiously. Pull the ribbon cables together with your palms, griping them as near the blue part as feasible. strive now not to bend them too much, as they are strong conductor. For the relaxation of the cables, simply lightly pull on the CONNECTOR to take away it from the socket, not the wires. if you pull on the wires, you threat pulling a wire out of the connector and complicating the mission. You’ll need to get rid of the memory module too if you have one established. Then, dispose of the four screws that maintain the board in area.

You’re going to assume this is a overdue April fool’s funny story, but it’s truly now not. the subsequent step is to preheat your oven to about 350º Fahrenheit and remember, your printer doesn’t paintings now- so what do you need to lose?



To prep the board for baking, eliminate the white barcoded sticker from the middle of the board and the black decal from the reminiscence module slot. the ones two stickers ought to be the best element now not able to ‘taking the heat’.

next, you’ll want to get out a flat pan, like a cookie sheet. You’ll need to raise the board above the pan so it doesn’t turn out to be soldering itself to it. To try this, you could both cautiously make 4 small tin foil balls to match over the screw holes (ensure the foil does not touch whatever soldered) or use my desired approach and find a few larger diameter screws and jam ‘em into the mounting holes. You’ll want to place the board with the heavy additives going through up, that is, the side with the memory slot, USB connector, and IC up.

once the oven reaches the goal temperature, location everything in and display it. You’ll want to depart it in for approximately 8 mins.

What’s taking place inside the warm box? properly, in case you haven’t figured it out but, the warmth goes to make all the solder at the board liquid, along with (with a bit of luck) the solder underneath that darn BGA chip. as soon as liquid, the open circuit should near and live closed after it cools; the board will feature normally once more.
