    I have a Brother MFC-3420C for a few years. All of a sudden it gave me a message Pls Open Cover. When I open the cover it gives a message of Cover Open. I tried searching for a paper jam but could not find any. When I put the printer in maintenance mode and type in 84 I receive a message of Machine Error 50.

    I could not find the any paper jam. I could not find a way to check on the bottom where the paper feeds through to see if there is any jam. But as far as I could see there is none.

Take out drum. After that, pull out ink cartridge. Return ink cartridge into drum and reinsert.
That cleared the code on mine.
If not, call Brother Tech Support at 1-800-284-4329

From looking at the online manual, seems to indicate that there may be something stuck in the printer paper path somewhere. It mentions a paper clip... A small piece of paper, any foreign object could be caught . Another possibility is that a sensor is either defective, or, if a mechanical (like a switch) the lever which activates the switch might be either jammed, bent, broken, making the system sense an error, when actually there isn't one. You should take a very careful look inside the printer, using a good light to help look in the paper path for some abnormality. Maybe you will get lucky and find!

Why my brother printer goes offline?

Is this a network (cat 5 cable) printer or a USB printer? Continual unplugging of a USB printer can cause issues where it will not recognize that device in which case you need to uninstall the printer and plug in to have Windows reinstall. If it is a network printer then you can either Repair or check settings by clicking "start" and type "control panel" (open when the control panel APP shows. You can "repair" or "troubleshoot" by right clicking on printer in "view devices and printers" or check "port" and make sure it shows the IP address of your printer and not "WSD". "WSD" is a windows chosen driver and notoriously has intermittent connection problems causing VERY slow printing and "offline" messages.

I think the machine is telling you to look inside for a foreign object or scrap of paper:

1) Turn the machine OFF
2) Open the cover
3) Carefully inspect inside for a bit of torn paper, staple, paperclip or other such foreign object - gently clear any problem materials. Do not touch internal parts if possible. Use tweezers for small hard-to-grasp objects.
4) Close the cover, and power ON
5) If the MFC cannot reset itself, or if no foreign material is found, the machine should report an error code, for example "Machine Error XX"
6) From this code, brother support should be able to diagnose and help with your problem

Printer indicates paper jam every few pages, but there is no paper anywhere in the paper path. If I open the top cover and close it, it will print a few more pages, then indicate another paper jam

Paper jams can be tricky to solve. The paper is usually stuck inside the printer mechanism so even if there is no visible paper jam, you will still get the paper jam error. Try this:

1. Turn off your printer
2. Open all trays and remove any paper stuck there
3. Locate the button to open the printer, open it and remove any paper stuck there also.
4. Repeate the above step for all buttons that you can find to access the inside of the printer
5. Close all doors and put back all trays
6. Turn on your printer

Paper light keeps blinking and won't print I have paper and it's set as default printer

It keeps blinking because there is a paper jam. Open the front cover and take out the toner/drum and see any jammed paper. Also, you can open the back cover, pull the paper guide down to see the rollers.

If the above does not work, take off the front cover. Pull the tabs on the side. Pull out the toner/cartridge. Look for a blue tab on the top, and you need to slide that from right to left. Put everything back and see if this solves the problem.


Paper jammed (Dell lase Printer 1720dn

Open the back cover and look for paper wrapped around a roller back there. That is the most common cause of the issues with this machine. The other thing you can try is to push down on the little flaps where the paper comes out of the printer. These get stuck and need cleaning/replacement all the time in the later life of these models (1720's).

Open cover show in fax - means what is the problem

this is telling you that the fax has encountered an error if you open the scanner cover this is where you put the doc in to send and close then open the front covers check that the cartridge is set properly and lastly check the paper path to see if there is a jam.. hope this help if you get an errror message describing fault let me know may be able to help more
