The pick up roller may be worn and in need of replacement. The slight grinding noise is the pickup roller trying to work but slipping

SOURCE: The auto-document feeder on our HP L7780 OfficeJet

I put an elastic band around the black roller as it doesnt seem big enough and it works nearly every time now. Have done this with another L7780 Pro as well which fixed it completely on that one.

Rollers not picking up the paper or picking too many pieces at once.


Pickup rollers can be easily replaced if you want to try that first. But the other noises could point to stripped gears or a different problem internally

My HP Officejet Pro L7780 faxes off & on. Motor is running w/in ADF, but the pick assembly does not grab paper


There should be a textured seperator pad, if that's worn out, replace it. Also check the ADF rollers should not be smooth. You may need to just replaced the ADF maintenance kit. It should include the roller assembly and seperator pad.

Paper Jam cleared but?


It sounds like the paper sensor in the paper try is broken or jamed. Remove the paper tray and locate the paper sensor. Check if it is jamed in the up position or if it is broken.

The auto document feeder does not pick up the paper


The pickup roller is probably dirty. Take a clean sheet of paper and put a small amount of rubbing alcohol at the end. Take that same end and place it in the automatic feeder and attempt to feed through for a few times. This should clean the pickup roller and allow paper to be picked up. Wait a few minutes for the alcohol to dry and attemt to feed a clean sheet of paper. You might need to repeat the process a few times

The paper feeder won't feed the paper through when faxing and copying. The rollers just keeps spinning. Help!


This is sort of scenario is usually caused by dust inside the printer. Dust has a way of preventing the sensors from detecting paper. Also it prevents the rollers from having a firm grip on the paper while picking paper. I will suggest you get a long handle brush and try to reach as far inside the printer as possible and brush (from the back and front). If you have a blower you may also use it to blow well into the interior of the printer (If you do not have a blower the brushing will still do if you do it well.) This, if properly done should do it. Brush especially the rollers etc.

The auto-document feeder on our HP L7780 OfficeJet Pro printer doesn't pick up the papers anymore. The 'gears' are spinning, but the papers aren't advancing. I've cleaned the rollers, but that still didn't...

Tray 2 Printing


Hi,

Couple of things for you to check out.

1. Is that you've enabled the second tray for the printer. This is normally automatic but to check go to:
START > Printers > L7780 > Properties
- Click the "Device Settings" tab
... then sort out the different setting so they are all correct such as paper size and of course "Tray 2: Installed"


2. The other more common issue is simply that the printer isn't sitting properly on top of Tray 2 and as a result it's not engaging the cog wheel properly to pick up paper.

This is one of those trial and error things where you pick up the printer and re-slot it down onto Tray 2 until it works properly.


Hope that helps...

Feeder won't pull paper


the arm in the printer is a cog setting you may have inadvertently knocked it out of alignment, it has free movement on a pivot and spring but when the printer uses it, it pushes on the mechanism to grip the paper and the roller at the bottom freeds it though, sometimes using to thick paper can do the samething. you would need to open up the device and locate the mechanisms, and make sure there is noting in the way of the controller's, i've seen a tiny piece of silver rapper make the same problem.
