    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!

When i on the printer the number 3&5 flashes on the printer

Those numbers could indicate a few things.
  • First number 3 means you need to check for paper jams.Turn on the printer.Open the scan unit or the front cover,check for any stuck papers inside and remove them.
  • Check the rear paper tray and remove any stuck papers.
  • Number 5 means you need to check the cartridges.Open the scanning unit and check if the cartridges are installed correctly and are the right cartridges.Install the correct FINE cartridges.
  • Turn printer off and on again.
  • If error continues you may have to replace the printhead.

Hi, My printer had a paper Jam and I am pretty sure some paper got stuck however i cant find any when lifting the top up.It now wont work and the alarm light is flashing ThanksJemma


Turn the printer off and on to see if it can automatically clear some or all of the jam. Many printers provide an error-code listing on the front panel display for the area where the jam occurred. If your printer shows an error code, be sure and check the printer manual to see if that identifies the area of the printer where the jam occurred. Step2 Turn off the printer. Step3 Remove any paper trays. Inspect them for wrinkled or damaged paper. Step4 Open any other doors that give access to the printer's paper path and to the toner or ink cartridge. Step5 If necessary, remove the toner or ink cartridge. Place it in a bag or away from light to avoid damaging it. Step6 266_a1.jpg If you find a piece of jammed paper, remove it by holding it with both hands and pulling firmly. The goal is to keep the paper from tearing. If several pieces are jammed together, try pulling out the middle piece first to loosen the jam. Step7 266_a2.jpg If the paper does tear, try rotating the roller gears manually to free the paper . Don't force anything, though. Step8 Replace the toner or ink cartridge and paper trays, close any doors you opened and turn the printer back on. Step9 If the printer paper jam message still appears, then there is still some paper in the printer. Reinspect the paper path.

If you still face the problem let me know..

My hp 2360 wont print, green light keeps on blinking, it says printer offline on the printer status bar

Make sure that cable to printer is attached and if printer still shows offline then in control panel for the printers make sure that you right click and choose Use Printer Online

What the flashing light means
The Power light can flash for several reasons:
? The printer cover is open.
? The printer is out of paper.
? A problem exists with the printer, such as a paper jam or a problem with a print

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.
