3110cn laser printer, Error code 077-901

Hi Gail,

Interesting issue...... Is your machine still under Warranty?

Is it possible that you could take a picture (or scan the page) so we can understand exactly what you're feeding thru this machine?

What paper settings do you use to print this "strange media"?

When you say "it got stuck"..... what got stuck? and where?

Do you still have the pieces you removed? If so, can you re-construct the paper and materials to see if you DO have every single little piece?

The 077-901 error indicates the registration sensor detects paper or an obstruction in that area. The registration sensor is the first sensor in the paper path that the printer uses to detect if the paper is moving thru the machine as it should. The machine knows how fast the paper should move thru this area and measures the time it takes from when the paper activates the sensor to when the paper leaves the sensor. The time difference represents the length of the paper. If the sensor is activated all the time, or after power off/on, an 077-901 error is the result.

Are you handy with a phillips screwdriver?

You asked if I was handy with a Phillips screwdriver? Can you tell me more? I really need to figure out something about this asap, and I haven't heard from anyone else. Is there a diagram or something online somewhere that would show me where to unscrew a part that would allow me to see 'inside' to look for little paper pieces? Would trying to remove the duplexer help any? Thanks for any suggestions.

Gail,

I think something is wrong with the email notification system. I didn't get notification that you replied to my earlier response to your post.

OK...... Let's get started:

I believe you have a problem with some paper or remnants from the jam stuck in the the registration sensor area. To test the registration sensor, you need to enter Customer Diagnosis mode on the printer. To do this:

1. Power off the printer
2. Press and hold the UP and DN arrow keys while powering on the printer; the buttons may be released when the LCD indicates "Diagnosing".
3. LCD should indicate "Customer Mode" and "ESS Diag" (or something similar).
4. Press the DN arrow to display "IOT Diag"; press the ENTER button.
5. LCD should indicate "IOT Diag" and "Digital Input"; press the ENTER button.
6. Press the UP/DN buttons until the desired DI-xx is shown, then press the ENTER button to execute the test.

The test we want to run is the Regi-Sensor test -- DI-3. Press the up arrow until the LCD indicates "DI-3 OFF" then press the enter button. The LCD should now indicate "DI-3 L 0". If it indicates "DI-3 H 0", then there is indeed some paper jamming the regi-sensor area.

I've included an image (click here) that should help you understand where the registration sensor is located and where paper enters the sensor area. This view is from the paper tray area (tray removed) looking up, and into, the tray area. When you can toggle the regi-sensor positioner and get the display to change from L to H to L, continuously, then you've cleared the jam. The number will increment indicating how many times you've cycled the positioner.

If you need better access into this area, remove the Toner/Drum carts and set them aside. CAUTION: Be careful you don't touch or scratch the bluish/green drum surfaces. Also, these are sensitive to excess exposure to light. When you take them out, put them in a darkened area or inside a box or file cabinet drawer.

Now, you can place the printer on either side and remove the bottom plate (4 screws using a #2 Phillips driver)

Let me know what you find, and good luck.

I sent this last Thursday, but I must not have done it right since it didn't show up here.

Ok, I did everything on your list a couple of times. Toggling the regi-sensor positioner does make the display change from L to H to L, but it doesn't stay at L when I remove the tiny philips screwdriver—it immediately goes back to H. And even if I restart, it still says there is a paperjam, though I cannot see anything at all, even with the lowest ink cartridge removed. I'm wondering if it would be worth it to buy a can of compressed air to blow through the slot where the paper goes. I can't see any way to slide a paper through it to remove anything that I'm not seeing.

The only thing that I wonder about is there are a couple of tiny square electronic things that are hanging down and look kind of odd, almost like they are a little loose and in the way of the sensor--could it be that they are dislodged somehow and part of the problem? If you can tell me how to attach a scan here I can show you what I'm talking about--or I can email it if you tell me where to send it.

So where do I go from here? Since this belongs to the church, the board needs to know if it is worth it to try to have it repaired, or if it will cost as much as a newer one since they've come down in price. I saw one for about $300 last week. It's just that I really like this machine and hate to replace it if there is any way I can fix it without it costing too much.

Thanks for all your help.

Gail,

I sent you a "PM".....

Hi Llynster,

I also have the same printer / error and seem to be having the same problem as rgbeard - toggling the sensor but still to no avail.

Do you have any other ideas on how to solve this?

Many thanks,

 JamieMz,

I am sorry to inform you that llynster has retired from the Dell Printers Forum.

He will be missed. If you try using the search finction on the right and use the keywords and at the end put llynster, it should bring up other threads that he responded to that might help you solve your problem.

Rick

I am having the same problem. Was there an answer posted to this question?
