I have Dell C1765nfw which will not print at the moment. It tells me there is a paper jam, but I can see no sign of one, either at the front or when opening up the back. I have looked a thoroughly as possible.
 
I did get an error message: 075-100

Any ideas what might be wrong, please?

Hello Nordvark.

Thanks for replying..... but I had already checked everything that your link suggests (and more than once!). There is no visible sign whatsoever of any paper stuck either anywhere in the machine. In addition, my husband was printing a document at the time it went wrong and it had been printing okay up to then and he was not aware of the paper getting stuck. It just suddenly stopped printing (although it did make a strange loud noise at around the same time!)

The printer seems to get ready to print as normal and is fine until the time when it should pick up a sheet of paper to print. I did read somewhere about another Dell printer with a similar problem and it said it could possibly be caused by the paper sensor. Apparently it can register as a jam if the paper does not reach the sensor(s) within a certain amount of time. I have no idea how to check if this is the case though, or indeed how to identify the sensor! :-(

Chris.

As I have not heard back from you, Nordvark, is it safe to assume that you cannot help me? (And that nobody else can help either?) :-(


FYI, I did manage to find the following info online: -



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 never even knew that 'Customer Diagnosis Mode' existed (what is the point of it existing if nobody is told about it?), but I ran the above test and got a reading of DI-3 L 0 which - if I am correct - tells me that there is nothing jamming the regi-sensor area. I cannot seem to find anywhere what the results of the other tests should be, or what they are testing for.

The results of the tests I ran were: -

DI-0 H 0
DI-2 L 0
DI-3 L 0
DI-4 L 0
DI-5 L 0
DI-6 L 0
DI-7 L 0

It looks a if DI-0 may be the culprit. After much searching, I managed to find details about to what the tests relate to (regarding another Dell printer, but presumably the tests are the same). It showed DI-3 as being the exit sensor and DI-0 as being the 'No Paper' sensor. So maybe there is a problem with the latter.

Do you know if it is okay to remove the cartridges on a laser printer before they are empty and then replace them? I was wondering whether I might be better able to look for small bits of paper that might be jammed inside if the cartridges are removed - although I do not remember seeing much of the inside of the printer before they were inserted.

I am not sure where to go from here. I have been trying to avoid having to phone Dell at all costs, as I have had some mega-stressful experiences with them in the past - and having to ring them now would be akin to all my worst nightmares occurring at once!   (I did attempt to use their live chat the other day, only to be told it was not available for this product!)

I have seen some extremely bad online reviews relating to this printer - and when searching for info about my problem, I was a bit alarmed to see  that someone with a similar problem with this model was told that Dell do not stock the parts necessary to repair it and that they would have to buy a new printer! I have only had my printer for just over a year and have really found it excellent up to now. It is so much better than our old one and I would be soooh upset if I had to ditch it. I got it for a good price (found for me on GTG, by Phillpower2 actually) but if I had paid the recommended price for it, I would be even more upset!   

Anyway, I would be grateful if, in the event of your not being able to help any further, you would kindly let me know. Then I will feel free to seek alternative help, either with Dell or elsewhere.

I seem to be extremely good at acquiring insoluble problems just recently!   

Many thanks,
Chris.

Sorry, only received notification of your post today. I'm sorry but this will need specialist advice from here on.

Just to say (for anyone who might have one of these printers) that I spoke to Dell and they told me that the error code I posted before indicated either that there was debris stuck somewhere, or the input sensor had failed. As I could not find any trace of anything being stuck in the printer, they eventually agreed to replace it, as it has a 3-year guarantee (which - being stupid - I either did not know, or had forgotten!). The replacement printer is now installed and working well.

 

For anybody who needs to contact Dell but does not (like me) relish the thought of phoning them, they did not answer my initial contact with them via their web form..... but answered me at once via Twitter and the guys there were incredibly helpful.

Glad to hear that all is now well and thank you for sharing the outcome so that it may help others
