Cannot copy or scan from ADF (autofeeder) on LaserJet 1536dnf MFP

Hi snafubetty,

I have a little different reset for you to try. Please check your private message, and let me know if this helps resolve the issue?

pcwizard, please stop providing the same 3 fix suggestions to every single person who reports the issue. It is not helpful. Those suggested fixes do not work (not even the special ones) and it's not your fault. HP needs to provide an alternate approach to resolve the reocurring problem. Snafubetty makes a good point and the BEST thing that you can do to help the people on this thread (as well as many others I am sure) is to send a link of this thread to an HP product or engineering specialist who can investigate the root cause of this issue and develop an alternate fix.

yeah, that doesn't work. I think it is either a sensor OR software. i spent loads of time looking on line and there is nothing because it all comes back as misfeeds and this is not a misfeed problem.

I think it is important to report it to HP because if i were a business that had a repetative issue with a product i would would like to know . . . it is an HP problem, not a user problem.

Hi igorO,

I can understand your frustrations, but in order for me to identify if this is truly a hardware issue or a firmware related issue I need to run the troubleshooting necessary to isolate the issue. If the printer is out of warranty you still have additional options to get the printer repaired or replaced. If the printer is still under warranty and is found to have a hardware failure with the ADF then you will be send a replacement printer to resolve the hardware issue. In either case (warranty or out of warranty) you will need to contact our customer support to complete the process and troubleshooting on the printer.

i called them and they said i had to subscibe to something before i could go any further . . . why would i do that if i didn't know if we'd have ANY answer, let alone one that would work.

Hi snafubetty,

Please try to call again, and let me know what happens?

[IgorO]

I understand what you need to do and you have completed those steps flawlessly with at least 3 individuals now to no avail. I don't know about the others but I called customer service and their recommendation was to send it in (my recently out of warranty unit - the whole thing) but could not provide an estimated cost to repair. Even if the repair is under $100 which is not likely, it's not practical for me to do that just because of shipping costs. Therefore, the issue goes unsolved for me and many others. I bought another multi-function unit instead from Canon and it's working well so far. HP lost at least one customer, got a poor product review, a letter to customer service, and is still not doing anything to solve an issue which is obviously a flaw in this product (and potentially others). You have done almost all that you can but HP has not. I manage products and if I worked for HP on this product, I would be all over this. I would be thanking you for bringing up a real issue that got past quality assurance. Shame that you won't escalate it to the folks who can do something about it.

I am having this same issue.

Please do not respond to this with a link to the mispick problem.  Although the display reports a mispick after the failure, that is not the problem.  If I place a sheet in the ADF, it feeds through perfectly.  If I place multiple sheets, they feed through perfectly, one at a time and without overlap.  The problem is a faulty sensor on the bottom of the ADF.

Like others here, the broken unit has just gone out of warranty (nice engineering), but I have the advantage of having two of these, so I can compare the behavior of the working one (which is still under warranty for 3 more months) to the broken one.  On the working one, as the paper is being fed through, there is a brief pause just before the paper moves across the scanning element.  On the broken one, this pause does not happen, and paper is continuously fed through until the machine errors out.  The sensor that tells the machine that the paper is positioned for scanning is not registering.

As far as I can tell, the ADF has two paper sensors.  The first one is a thin lever on the top that gets pushed forward when you put paper in the ADF.  This one tells the device that paper is loaded.  The second one is another small lever on the bottom of the ADF (you can see it to the left of the white bar when you lift to expose the flatbed).  This lever falls into place by gravity when the lid is down, and is positioned to be triggered just before the paper moves across the scanning element.  Presumably, triggering this second sensor causes the brief paper feed pause and tells the scanning element to begin capturing.

On the broken unit, if I fidget around with the second lever a little, I can sometimes get a successful scan through the ADF.  Since this device is not worth sending in to get repaired, I will be focusing on that second sensor when I tear it apart.  Hope this is helpful to someone.

I had the same problem. Try cleaning he scanning plates. Yes there are 2 of them. After lifting the ADF there are two glass plates - one smaller on [1" x 13"] that's for the ADF and the larger one for the flatbed scanner. Clean them both. And give it a try. NOTE: there is a "red" sensor dot that seems to activate the ADF scanner - small plate. make sure you clean that area good.

I also opened every thing I could on the ADF to see if that helped. Anyway, got it to work - for now.

Hope this helps. Dont waste your money on Tec Support! Just trash the unit and look for one on sale. The priners are always cheap. They kill ya on the consumables - toner, ink etc.

The problem is the ribbon cable that goes from the adf to the main pcb. I work on these units all the time and this is  a major issue with this and the 1415. It should definitely be recalled. There is no firmware fix or reset fix so that is a waste of time. Replace the adf cable.....
