Select from the products you own. I am interested in getting ahold of that Ceramic filament to attempt a candyfab heater design. If you look very closely below the circuit board on the right, you might see a tiny little third circuit board: Let HP identify any out-of-date or missing drivers and software. Thus from a crude economic perspective that is, ignoring the extreme environmental irresponsibility of the remainder of this thought it could possibly make more sense to just go ahead and buy a new printer when you run out of ink. Discussion threads can be closed at any time at our discretion. They need to isolate the AC line from the output.

More slots on PCBs found in this teardown of a laesrjet credit card reader video. One thing that we have alluded to thus far is the mechanical complexity of the machine. Please verify your product is powered on and connected, then try again in a few minutes. Email list of drivers. It sits on a dc brushless motor on a little circuit board.

HP Color LaserJet n (Government) Overview – CNET

Is my Windows version bit or bit? The lenses are optical glass and have an anti-reflection coating. In several places there are even complex molded pieces that serve no purpose other than to guide and confine a wire bundle without the need for additional fasteners. Much respect to you. Any idea why I keep getting a black line down the middle of my print-jpbs?

If you look closely in the upper left photo, you can see two cokor fat high-current wires that go of to the fuser. With normal humidity, we could get good plots all day. On a laser printer, the laser does the same thing: This HP Printer is new, never used.

The HP Tango X writes the book on bookshelf printers. Dirty from use and storage; could use a more thorough cleaning. Here is laserjeet surprising element from the optics package.

This board contains up humidity sensor— interesting little component. If you want plastic gears, this printer offers a good value for your money. One or more of the values entered is not permitted. We are unable to determine your warranty status for the product and serial number provided. That was far more interesting than I expected!

The serial number provided does not match the previously selected product. My advice if you want to recover these glass lenses: If you put it up to the light you can see that the resistive track through ,aserjet heater winds down to the end and back twice.


Hp color laser jet. Deep in the inner sanctum of the printer hides the optics package.

This printer arrived in good overall condition with a low page count lasermet only 35, pages. Ink cartridges will need to be replaced.

These are the only parts of the machine that I was not able to remove in a reversible process.

There were two little circuit boards hiding in there. You can look through the edge where the circuit boards are installed to see the two little laser cans.

The replacement PCB just had an 8 pin 16F series PIC microcontroller onboard — presumably they can reuse these and also possibly fix the page count even lower. Had you ever tried printing an image of US currency on this printer in order to determine if it has anti-counterfeiting measures built-in?

The right cover comes off, and then we unscrew the back panel.

Thank you for the interesting read.
