Question about Canon DR-3080CII Path-Through Flatbed Scanner

Canon DR-3080cii paperjam

The scanning software keeps telling me "paper jammed in scanner; clear paper and continue. (-4426)" We've cleared everything we could (short of taking it apart). Where are the sensors for paper jams?

    This seems to be the rollers. I have scraped the obvious gunk off them but am still getting the paperjam error and it stops about halfway into pulling the paper in. Is there a replacement kit out there for the front rollrs? I see 6915A002AA out there for the back rollers.

    After job finishes it is still looking for paper and throws a 4426 paper jam error. It is an intermittent problem. I tried to clean all the sensors i could find.

The 3 paper sensors are located along the center of the paper path. They are: Registration (lever type) on the bottom between separation & registration. Look for lever damage or torn paper. Scan Start (reflective) on the top between registration & front reading roller. Clean the sensor window with qtip & alcohol. Delivery (lever) at the eject roller. Same as reg, but harder to see due to location.The feed roller exchange kit is 6915A001. The rollers in this machine are not considered user replaceable.

Documate error 8


I am a Support Engineer with Xerox Scanners.

E8 is a Paper Jam error that could be caused by:
- paper crumpling during scan.
- paper is multi-feeding all at once instead of feeding separate.
- scanner continuously tries to feed after paper has fed through.

if the paper is crumpling during the scan, make sure the inside of the scanner is clear of any obstructions. use the paper guides in the ADF tray to keep the paper straight when feeding in.

if the paper is multifeeding while scanning, fan out the pages before inserting them into the scanner. if problem persists, try cleaning the rollers with rubbing alcohol and a lint free cloth.

if scanner tries to continually feed after the paper feeds through, the ADF tray will need to be reseated. open the scanner and remove the ADF tray at the top. line up the 4 keys at the bottom of the tray with the 4 corresponding key slots inside the scanner. push the tray back until it clicks into place.

We also have an extensive support site and knowledgebase at

The scanner keeps jamming. i try to scan form the document feeder &the papers keep getting stuck. It will not complete a scan!what do i do?

In summary: * Very unintuitive, convoluted and unpleasant to use (same on Win2K as XP) - sometimes the SW hangs during scan and needs a reboot - sometimes the SW crashes with a dialogue "try reinstalling HP software", and needs a reboot - sometimes it scans and after conversion to pdf
Advantages: I cannot see any advantages with this product
Disadvantages: Software is convoluted and unreliable, paper jams are difficult to clear

function showHideReviewText( sType ) { if ( sType == 'more' ) { document.getElementById( 'review_text_full' ).style.display = 'block'; document.getElementById( 'review_text_short' ).style.display = 'none'; document.getElementById( 'review_title_link' ).onclick = function() { showHideReviewText('less'); }; } else { document.getElementById( 'review_text_full' ).style.display = 'none'; document.getElementById( 'review_text_short' ).style.display = 'block'; document.getElementById( 'review_title_link' ).onclick = function() { showHideReviewText('more'); }; } } ...with a dialogue "try reinstalling HP software", and needs a reboot
- sometimes it scans and after conversion to pdf every page is blank
- very occasionally it scans a document properly
*If the sheet-feeder jams is says to refer to the documentation to clear it, which doesn't exist. There is no way to clear the jam except to pull hard & hope. No levers to release it like one would expect.
*Frequently has error ...
...cycled to work again.

Everything has to be started by pressing a button on an application called "HP Director". There are 4 apps started from this:
1) Scan Picture
2) Scan Document
3) Make Copies
4) View & Print
also Help
also Settings (which are used in conjunction with settings found in (1) and (2)!)
- Each application has to be exited to return to "HP Director"
its a worst scanner
and prone to jamming problem

ADF paper jam, when there is none

If you are receiving an Error Code 103 or a Paper Jam error, but there are no pages in the ADF (Automatic Document Feeder), follow the steps below:
  1. Close the scanning application (such as PaperPort)
  2. Turn off the scanner and the computer
  3. If you have a combination ADF with a Flatbed scanner, unplug the ADF cable from the base of the scanner
  4. Plug the ADF cable back in
  5. Turn on the scanner power
  6. Turn on the computer
  7. Try scanning again
For a Paper Jam or Error Code 103, make sure that the ADF cable in the rear is connected to the scanner base. Check the flatbed to make sure that it is clear. A page incorrectly placed on the flatbed may interfere with a page feeding through the ADF.

If your scanner stops scanning due to a paper jam in the Automatic Document Feeder (ADF), a warning dialog box appears after a few moments.

To clear a paper jam:
  1. Open the Automatic Document Feeder cover.
  2. Remove the jammed paper and close the cover.
If you are receiving a paper jam error, or if the scanner is running continuously, check to make sure the paper sensor arm is not stuck down.
  1. Open the Automatic Document Feeder cover.
  2. Look for the small black plastic arm
  3. When you press on this arm, it should move freely up and down
  4. If the arm is stuck down, please contact Technical Support for troubleshooting options
  5. Close the ADF cover.

Dr 5010c feeds one to five sheets, then stops

Clean the rubber rollers (pickup and ******) with a damp cloth, loosen the papers to be scanned. Clean all the rollers in the scanning path. What is the eror that is displayed? Download the user manual from this site (5010um.pdf). Change the rollers if they are old.

Resetting PaperPort after paper jam

I found the solution to this problem. Whenever the paper jammed in the feed tray, I was pulling the jammed paper out without opening the door of the feed tray. Apparently, PaperPort gets confused and does not know how to proceed. Now when I get a paper jam, I open the door of the feed tray, take out the paper, click on the paper jam error message in PaperPort, reset the paper in the feed tray, and then hit "scan." Works like a charm.

My Canon DR-2050C keeps jamming when I try to scan more than 1 page???

I finally solved my problem. Now it works like new.


- The spring that returns the next sheet detector (small black plastic rocker arm between the two rollers on the back side) came off. So the scanner cannot detect transition from one page to the next. This spring is located inside the device and you cannot fix it from the outside.
- You know if you have this problem if you don't hear a "click" sound after each page is scanned. Without the spring attached the rocker will not return on every page. When it doesn't return the scanner think it is still on the first page and will not scan the next page. The "click" after each page is NORMAL. Without the click is the first sign your spring came off.

Solution (Only recommended for people handy with hardware and the unit is no longer under warranty)

1. Turn off power and unplug the device.
2. Pop off the plastic cover to the back of the scanner
3. Remove the screws that holds the plastic cover to the back.
4. Remove the screw by pushing on the retainer clips. DO NOT loosen any gears or motors.
5. Locate the rocker arm and re-connect the (very small) spring

6. Warning - if the LED light pipe falls out be careful how you put it back. This is a transparent widget at the top to route a LED light to the top of the device to indicate the power on status.

Sorry I didn't take pictures. If this sounds too complicated, send it to Canon for repair. Took me about a day to figure out exactly what was wrong and how to disassemble the scanner to fix it.

Good luck.

Does it say clear jam immediatly or does it start to run then declare a jam?
If it starts then tells you to clear a jam and no paper is in the machine, your feed rollers are shot. Smooth like trying to drive a car on ice.
If it says that all the time, no attempt to feed then you have a sensor either dirty, knocked out of place or something stuck on a sensor.
Either in the paper path or in the scanner.
