HP OfficeJet R80
Hi! Does anyone still monitor this site? I sure hope so! I’ve had this printer for many years with no other problems other than replacing a burned out light bulb. A couple of months ago I couldn’t get the documents to feed. Not knowing the top had come up and was not clicked down, stupid me stuck my fingers into that area and felt around. Heard a ‘snap’! Now the papers will feed in – get mangled coming out. And – it keeps trying to load documents when the input tray is empty. I thought about opening it up and trying to glue or fix the piece I snapped(?) I have ordered the ADF (refurbished) yet they can not or will not provide the instructions to replace the ADF. I am a bit familiar with taking it apart since I did that to replace the bulb. However the ADF is different. Can you help? Thanks in advance! 🙂

Experienced technical support provide their insights in answering this question :
I always just look at it and see what needs to come apart. I almost never use manuals since they slow things up. What I suggest is just look at the ADF you get and it will give you an idea of what needs to come apart to replace it.

How to Identify and Fix Common printer Problems ?

In multifunction or all-in-one printers, fax machines, photocopiers and scanners, an automatic document feeder or ADF is a feature which takes several pages and feeds the paper one page at a time into a scanner or copier, allowing the user to scan, and thereby copy, print, or fax, multiple-page documents without having …
Dust, paper fiber, and other debris might accumulate on the pick rollers and cause paper feed issues. To help prevent paper feed issues, clean the rollers inside the ADF. Open the ADF cover. Lightly dampen a clean, lint-free cloth with distilled water, and then squeeze any excess liquid from the cloth.
Slide the edge guides on the input tray of the ADF all the way outward. Place the first page of your document in the input tray with the printed side facing up and the top edge facing into the feeder. Slide the paper into the feeder until it meets resistance. Then slide the edge guides over to the edge of the paper.
The paper has holes along both sides that fit over the sprockets located on the feeder wheel. When the wheel turns, it feeds the paper into the printer. The holes are torn off the paper after the printout is complete. And, yes, printers still use this type of feeder mechanism.
The cat feeding station is automatically refilled from the container above as and when your cat makes space in the bowl by eating the food. These types of dispensers are suitable for owners whose sole aim is food availability via a full bowl, as they do not offer the opportunity to regulate portions or timings.
The automatic feeder has broken that bottleneck. The feeder is simply a machine that takes feed from a central hopper or bin out to the birds continuously all day. In place of having to fill a score of separate feeding troughs, the poultryman fills just one – the hopper – and does it just once a day.
The technical term automatic document feeder (ADF) describes an part of an device which allows it to automatically pick up several paper sheets and feed them one page at a time into the device.
This issue is typically caused when the Auto Crop feature is enabled within the scan settings. This feature can only be used from the Flatbed, so the machine`s scan function will bypass the ADF by default.
Use the operator panel on the printer to enter the menus. Locate the Paper Menu and select that menu. Locate the Paper Size/Type setting and select that. Find and select MP Feeder or Multipurpose Feeder and select that.
Continuous form feed and friction feed are the two types of paper feeder mechanisms. Dot matrix printers use continuous form feed, and laser printers use friction feed.
In general, paper feeding methods are divided into two types: manual feeding and automatic feeder feeding. When the manual feed is in printing, the user holds the paper directly from the printer`s paper feed port. However, manual feeding can only feed one sheet at a time, which is very inefficient.
When you scan, copy, or fax pages from the automatic document feeder (ADF), the printer does not pick up any pages. The following error message displays on the control panel: `Document feeder mispick. Reload then press [OK] button to continue`. The ADF might also pick up multiple pages instead of single pages.
Press the ADF cover firmly from top to close it.
A feeding machine or an automatic feeder consists of four major components (Fig. 16.4): a feed container (hopper), a mechanism for feed distribution, an electrical power supply for the distribution mechanism and a control unit for starting and stopping the distribution mechanism.
Automatic feeders can be classified according to their energy supply as being electric, pneumatic and hydraulic-type feeders.
Sheet feeder: Holds the blank paper and automatically feeds the paper during printing.
Smart Feeders

These devices connect to Wi-Fi, so you can use your phone or tablet to control and check on feeding times and portion sizes. Smart feeders also have extra features, like the ability to control the amount of food given, the ability to feed slowly, and automatic reminders.

This is a super convenient feature if your office regularly makes a lot of copies, saving both time and potential frustration. Most automatic document feeders are capable of handling anywhere from 20-50 sheets at a time, depending on the printer model.
Yes and No. If you work in a large corporation and handle large volumes of paper, you need an ADF. However, if your printer is for domestic use with small printing tasks, you might not need an ADF.
The message “Document Feeder Kit Very Low” on your HP Color LaserJet M525 series printer is a warning that you have scanned the maximum recommended number of pages through your auto document feeder at the top of your printer.
Use the operator panel on the printer to enter the menus. Locate the Paper Menu and select that menu. Locate the Paper Size/Type setting and select that. Find and select MP Feeder or Multipurpose Feeder and select that.

Upper Feeder Jam
ANSWER : The only thing that can cause it is some sort of obstruction in the paper path. That would be the small section before the paper comes up from the bottom tray and intersects with the paper feeding from tray 1. The best way to clear the unseen piece is to shove a stiff piece of paper or plastic down the path. A piece of file folder is usually enough to dislodge whatever.

Optional 250 Sheet Feeder Tray (Q5931A – Tray 3) Constantly "Jams"
ANSWER : You don’t say if the paper moves at all. That’s key in determining the cause. If it’s not moving, then try swapping the rollers with tray 2. If it is moving out of the tray, then that would indicate there is some obstruction it is hitting on its way out of the tray. Hard to troubleshoot remotely when one doesn’t have specific details since we can’t see what is occurring.

error code/words "Document in ADF" Press [OK]
ANSWER : I am assuming that there is no document in the ADF. When you insert a document in the adf, it pushes down a thin plastic arm. The other end of the arm goes in and out of an optical sensor. Could be either the arm is stuck so the printer thinks there is paper in the feeder or that there is some dust or foreign object that got stuck blocking the optical sensor.
