Hi,<br />
<br />
Have a HP 4000n printer, was reading up on if there isnt a paperjam it could be a stuck sensor. &nbsp;Is there anywhere listed that shows a picture of where that &quot;sensor&quot; would be ? &nbsp;Also, i am wondering if the pickup rollers need to be cleaned too ... once it tries to print, not to sound trivial , but its making a very odd groaning noise and then I get the paper jam error. &nbsp;Most of the time, the paper doesnt even leave the bottom tray. &nbsp;Not being a printer repair person ... I would need to try to find a diagram so if I rip this thing apart and order parts I can figure out how to put it back together. &nbsp;Any advise ?

Hi,

Have a HP 4000n printer, was reading up on if there isnt a paperjam it could be a stuck sensor.  Is there anywhere listed that shows a picture of where that "sensor" would be ?  Also, i am wondering if the pickup rollers need to be cleaned too ... once it tries to print, not to sound trivial , but its making a very odd groaning noise and then I get the paper jam error.  Most of the time, the paper doesnt even leave the bottom tray.  Not being a printer repair person ...

A printer is a peripheral which makes a persistent human readable representation of graphics or text on paper or similar physical media. Traditional printers are being used more for special purposes, like printing photographs or artwork, and are no longer a must-have peripheral; 3D printing has become an area of intense interest, allowing the creation of physical objects. An image scanner is a device that optically scans images, printed text, handwriting, or an object, and converts it to a digital image. Hand-held scanners, where the device is moved by hand, have evolved from text scanning "wands" to 3D scanners used for industrial design, reverse engineering, test and measurement, orthotics, gaming and other applications.
