Old printer's circuit board design

Do you guys at HP ever release confidental data of old products?
I have an old HP PSC 2500 and I would like to use some of its parts to build my own 3D printer.
Therefore it would be amazing to be able to use the printer's original controller board with it's powerful
133MHz processor and reprogram it with some homebrew 3D printing software. (I think of all the great features I wouldnt have to rebuild myself: Ethernet, Wi-Fi, USB, Motor & Sensor interfaces, Power Controlling unit)
But for this Project I would need the circuit scheme of the Controller Board or the low level functions source code and some hint on how to connect the board's programming plug.
If you're not going to release any of these information (which is regrettably very likely) please tell me at least the part number of the microprocessor of the printer. (Or provide me with an email address of someone who can help me with my question)
Remember that I need this only for private use.

Here is part of his earlier post for general info:
As for the mosiac, some cameras were getting that in
RAW conversion. I do not think the update patched any
RAW conversions, that will probably coem with an OS
update that should also be along any day now. then
you may see some imrovement, though again it would
depend on what they update and what camera you have.
<...>
Yep, that ended up being slightly wrong as it turned out there really was no update of RAW decoders in 1.0.1 - they spent some time on it instead and thus we have 1.1 coming up, which defiantley has RAW decoder updates for at least some cameras.

Is there a gerber view to view printed circuit board gerber files?

Please advise to which gerber viewers are good for Mac products. I use windows at work but have Mac products and operating systems at home? Do you havea suggestion for a free gerber viewer for printed circuit boards gerber viewers.

There are several. Gerbv, MCN Gerber Viewer, Kicad and more. I have a list at:

Swapping circuit boards for an internal hard drive

My story may be a bit long and roundabout, so please try and bear with me as I explain.
My PowerMac G5 is 4.5 years old and over the past few months, the DVD and my secondary internal hard drive, both the originals that came with my computer, have been slowly dying. I finally replaced the DVD drive the other day and was little by little copying the data off my secondary internal drive before it completely failed. One thing that seemed to help the internal drive run more smooth was unplugging the power cable and plugging it back in. A worker at an Apple store's Genius Bar also suggested swapping each internal drive to the bay that the other was originally in, to see if that helped at all.
Anyways, in the end, the drive was giving me so much trouble and I had unplugged/plugged the power cable so many times that eventually the part of the circuit board that holds the pin connectors straight broke off, so now I had no way to get my data off the slowly failing drive. Another visit to the Genius Bar and I was told that the drive was as good as done, but not wanting to believe that the majority of my film projects were gone forever, I contacted a store across the street from my old NYU dorm called Digital Society. They told me that the circuit board on the drive needed to be replaced and that the new board had to be taken from an identical drive. I soon realized that the primary/system drive of my G5 was in fact identical. So, after running Time Machine, purchasing new primary and secondary internal drives, re-installing the OS and doing a Time Machine restore - which was flawless - I took my two drives back to Digital Society where they swapped the circuit boards rather quickly.
Now that I'm back home, I was easily able to recover all my data from my failing drive... only after having its circuit board replaced, the drive is showing no signs whatsoever of the read/write difficulties and failures that it had been showing prior to the circuit board swap, which leads me to a few questions
a) Was it really the drive that had a problem, or the circuit board itself? Is there anywhere I could buy just a circuit board without having to buy a new drive just to get a circuit board? The drives in question are 400 gig Hitachi Deskstar, model #HDS724040KLSA80. While I'm not entirely sure the once failing drive should be trusted again, my old system drive - which now has a busted circuit board on it - still works perfectly fine.
b) If I'm able to get a new circuit board, how easy is it to replace myself? The guy at Digital Society did it very quickly and for a price of $120. Are there any video tutorials?
Thanks!

Lot's of good question Will,
Hard drives are not what they used to be, if your work is important I'd replace them every 3 years & have 2 backups in the meantime.
I doubt you can get the circuit boards separate without buying a while questionable drive.

I have been using Adobe Photoshop Elements 11 for two years. I got a new printer and installed it although I did not remove my old printer from my computer. I used this program and my new printer for quite a few months, but today I deleted my old printer

I have been using Adobe Photoshop Elements 11 for along time now. When I first used the program I had a different printer than I have now. Although I changed printers I never removed the software from my old one. Now this was never a problem until today. When I choose a printer I still had option to use the old one but always chose my new HP Envy 5530 and Adobe never had a problem printing from that new printer. However today I decided to remove my old printer from my computer and now my Adobe cannot find my new printer. How can I make it find the HP printer?

Try this --
Go to the bottom of the link I gave you, and you will see
click that link and then click the chat button to talk to an Adobe agent

I am trying to use the RS232 to control a circuit board. It would have to simultaneously output SerialClock, DataIn, and Chip Select signals, while also receiving DataOut signals; therefore 4 signals total. Does anyone know if it this is possible?

I am trying to splice 4 wires out of the RS232 serial cable (the 9-pin type) and wire them to a circuit board. The 4 wires would control 4 signals: DataIn, DataOut, SerialClock, and ChipSelect. The serial clock would synchronize the DataIn and the ChipSelect is asynchronous. DataOut must coincide with SerialClock also; therefore there are 3 signals that must be able to switch concurrently. All the handshaking enabled by RS232 is thus unnecessary in my opinion. Does anyone know of how this can be done?

How do i make my mac forget an old printer?

i have a new printer and want to make my mac forget my previous printer, as it continues to automatically look for the old unit. Any helpful tips?

Open Print & Scan preferences. Delete the old printer. Add the new printer.

How do i remove my old printer icon/software?

i recently bought a new printer and installed in on my mac, and am no longer using the old HP as the wireless radio doesnt work. the HP icon is still on my dock, and i want to remove the software and the icon. new printer is installed, but the icon isn't on the dock, and i have to search for it when i want to scan something. also, i want to put my cisco router icon on the dock as well. i am a longtime PC user who switched to this mac in march last year. still learning the ropes!
thanks!

Removing Old Printer:
On your Dock, drag the Old Printer icon away from the dock. (A puff of smoke should show - this means you have removed it from the Dock)
Navigate to [System Preferences > Print & Scan].
(On the left of the Print & Scan window will be a white colored column, titled 'Printers', with a '+' and a '-' symbol at the bottom.) Click on the Old HP Printer, that is located in this column, and click the '-' symbol that is at the bottom of the white colored column titled 'Printers'.
Select 'Delete Printer' when the dialogue box shows.
Adding Printer Icon to Dock:
Navigate to [System Preferences > Print & Scan].
Drag the New Printer Icon (In the White Column titled 'Printers') and place it on your Dock.
Please note: You cannot add the Printer Icon next to the Icons near the Trash Can.
Keep moving the Printer Icon along the Dock until a gap opens for you to place the Printer Icon.
Adding the Router Icon to Dock:
As far as I am aware, this is not possible. Wi-Fi settings are located on the Title Bar at the top right hand corner, of every window.
There is no need to have the Router on the Dock.

How do I get my old printer "HP Laserjet 4mv" to work on my newer Macs with OSX?

How do I get my old printer "HP Laserjet 4mv" to work on my newer Macs with OSX?
There is no HP support for this old printer. I have tried to connect via ethernet (thru ethernet router), and it does not show up in printer preferences. The printer worked fine on system 9x but when I went to my new macs with system X no luck. This is a great B&W printer that prints at 18 x 24". I would like to keep it and not junk it, but its been sitting on my desk unused for some time now. Any thoughts or JUNK IT! Thanks, R.T.

Does anyone at Apple have help for this sort of question - I too have an old printer (HP LaserJet 5MP) that I would like to keep using on my Mac. (Mac OSX 10.6.8).
I got it working by getting a USB cord that connects to it - but every once in a while it just stops working for weeks. The mac 'sees' it and it sends the data because the printer lights start blinking but then it just doesn't do anything. Is there no one who can tell me (and raterada) how to get some new life into these old printers. I would rather not add this (and a new toner cart) to the landfill just yet. . .

I have purchased a new printer. It is the same make as my old printer. How do I remove the old printer from my Mac?

I have purchased a new printer. It is the same make as my old printer. How do I remove the old printer from my Mac?

you could see if that make of printer has an uninstaller (may come with the installer)
or go to preferences, print and fax, and press the minus key ( - ) which should maybe remove it. Or ,do a a find, then type in the make of printer, and anything that looks like a printer driver for that make, well, maybe it's gotta go
just an idea

How do I transfer the email address from an old printer to a new printer?

Hi, I have recently bought a new printer and I wish to use my old email address that is linked to my last printer. However, I cannot transfer it. Even if i change the email against the old printer, it wont allow me to add it against the new printer. But, allows me to change and re-use against the old printer.
Any suggestions as to how i can transfer this?

Broken coax cable from circuit board to Airport Extreme

I picked up this 1.25Ghz-DP/1024MB/FW800 off the internet knowing that it did not come with either the Airport Extreme or the Bluetooth (1.1) module. No big deal, since I have an AE and would be looking for the BT Module. To my surprise, its "AE/Bluetooth-ready" status was compromised by the removal of the AE card using a pair of side cutters (or some other crude cutting tool), leaving a frizzy antenna cable running back down into the space between the chassis and the case. It would appear that the BT antenna is intact, for what it is worth.
I know there would be some challenges, but I am wondering if the part is available that includes the circuit board, the antenna, and the antenna coax leading from the circuit board back to the connector on the AE. Or maybe the part numbers?
I plan to use this for an older version Digidesign's Pro Tools, so I am going to remove the two four-port cards (one FW, one USB) and replace them with the PT Mix Core and Farm(s). I would prefer not to go with the USB dongle, since I know there can be flakiness with USB and PT. My alternative to taking the plunge with a soldering iron and some parts would be to get an AEBS nearby and connecting with ethernet.
The computer sees the card in System profiler, but without the antenna fully deployed, it fires blanks. Are the resources for the connector and cable that could be put together to paste it back in place or better yet, a place to get the complete unit to change it out. I guess I would be looking for the BT module, too as long as I am at it, but that is not a critical issue.
Thanks---Dave Iverson

Hi Dave,
Here is a third-party external extension antenna that might replace the existing stub:

Installation in a G4 mini-tower is easy; you only need to remove a PCI slot cover on the back to run the cable outside the box. I have no personal experience with this; just something I found in searching after I read your post.
Danny,
Welcome to Apple Discussions!
Looks like the above product should work for an iMac. Check the list of instructions on the page I linked to see if they list your computer. I suspect you have to take something apart to run the cable. Also check the iMac G5 forums to see if someone there has already figured it out for that model. The iMac G5 hardware is nothing like the G4 mini-towers that are the subject of this forum area, so your chances of getting the right answer for your specific computer are better in the other forum I linked.
If you are having trouble figuring out how to start your own thread (so many people do that I must ask), see this Apple info:

Purchasing new HP Photosmart printer which will require new OS X Mountain Lion driver software. Which steps do I take to install new printer, old printer HP still on iMac.

Purchasing new HP Photosmart printer which will require new OS X Mountain Lion driver, which installation steps do I take. Old printer still on iMac.

Hi Carol 22,
Thanks for the post. Depending upon the printer model, print drivers may be available from ASU. If not, then go to hp.com and download Mt. Lion drivers to your iMac. After you complete the hardware setup of the printer, if connecting wireless, then connect the printer to your network and then complete the installation and add the printer. Then you can go back and remove your old printer. I hope this helps...Good Luck!
I work for HP but my posts and replies are my own....Thank you!

New T430s has exposed circuit board

Thought I would start a new topic after mentioning it in a thread about loose arrow keys...
I can see the inside of my T430s from a gap at the back of the keyboard. I can actually see green circuitboard exposed there if I shine a flashlight through the crack above the F7 key. There is some printing on the board that says "R186".
The only thing I've attempted to open on this laptop is the RAM compartment, so its not from tinkering. This is how my T430s was built.
A couple photos:

Link to image 2
At least in my case, the Thinkpad claim to spill resistance seems to be defeated. I've owned more than a few laptops (and used more at work) and never, ever noticed an exposed circuitboard before.
Wondering who else has this and what I should do...
Edit: The camera couldn't be placed any farther back to show the full width of the gap, since a piece of black fabric is just below the visible circuitboard... the camera only picks up blackness from that angle but my eyes can see what is basically a 2.5-3mm rectangular gap between the top keyboard bezel and the rim of the notebook body. In total, the gap runs from about the right edge of the F5 key to the left edge of the F10 key; Various things are exposed but the circuitboard part is only about the width of a key.

First, when you opened the memory cover, you were working in the area that holds the keyboard in place. There was one more screw involved and it is right where you were working, inside the memory cover. The keyboard goes in last during assembly, right before they close up the memory cover. When installing the keyboard you slide the front lip under the bezel and push it forward to get enough room to be able to get the tabs at the back of the heyboard enough room so that they can get bu the other edge of the bezel. Then, you gently pull/push the keyboard back to center it in the space. Either your bezel is defective or that last step didn't get done correctly. (My description probably makes more sense if you have done it a hundred times.) If it were mine, I would take off the memory cover, remove the keyboard mounting screw and slide the keyboard into place. If my description makes no sense, you could call service.
