    hello if you take of the back door, inside you will see the fuser unit which is also called the heater unit, there may be covers on either side that have to come off otherwise look for the screws that hold it in they are shiny screws. be careful how you unplug the unit , then all you need to do is take the unit apart. it splits in half, you will see the paper holding down the sensor. if you need more help let me know. good luck brother sr tech

If you have opened rear door, inspected and don't see any paper, try opening front cover, remove drum unit and look at the underside of drum unit right in the middle. there is a slot that needs to be open. sometimes a small scrap of paper will get lodged in that slot and prevent a sensor lever from operating correctly.

Carriage jam error


A paper jam

If you've had a paper jam, normally after you clear it, a small amount of paper sometimes gets left behind and gets shunted onto the sidewall of the printer by the carriage, which stops the carriage reaching its full travel and throwing up an error, rendering the printer unable to print or carry out any other function. Simply remove the paper and switch printer off and on and it will reset.
If you have an error of any other kind, many remedies and fixes for these can be found on my website http://www.the-inkstore.co.uk/frame/pages/epson.htm

I have a 5650 lexmark printer and it keeps saying paper jams but there is not paper anywhere.. how can i find a solution... when you load paper it keepps getting stuck.. help


There could be something blocking the paper path. Try to shake the printer upside down. You'll be amazed of the things that falls off inside the printer. Also, make sure that there's no paper left inside the printer. Tiny pieces of paper will still lead to paper jams.

Turned it on and it says paper jam. There is no


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

Says Paper Jam but ther is no paper jam


It appear from here that the exit sensor may be dirty and you can use canned air and blow it out.

You may also be missing the paper out sensor that is located at the bottom of the printer oposite of the paper tray when you pull it out. When the flag arm has fallin out, it will give a false paper jam error when the last sheet has printed from the tray, not knowing or detecting that the tray is now empty.

Canon MX300 Paper Jam


I have the same problem - every time I turn on my printer now, the alarm signal shows up with "Paper jam" but when I check for jammed paper, there is none. So I think there's something faulty with the printer. Is there any way to reset it? I've looked everywhere but can't find it.

Hp Color LaserJet 3500 Paper Jam


The only way to find paper remnants is to unplug the printer and inspect the paper path. It also helps to have a good focusing flashlight, skinny needle nose pliers, a can of compressed air (used sparingly) and a long thin probe. Your specific printer should be giving you jam messages with a location code as well. I?ve attached a link to an HP page containing a diagram of the 3500 paper path and the error code jam locations: http://h41206.www4.hp.com/webapps/IV3/node.iv?locale=en_us&prodSeriesId=315862&node=prodITRC%2FNL_HW_IPG_plakCLJ3500_EN_01_E%2FN1%7C6%7C9&prodTypeId=18972&serverId=1#src I solved this problem in my shops years ago by not letting anyone else clear jams OR insisting that any paper removed as a result of a jam is given to me. If any corners or pieces are missing I know what to look for and approximately where. Good hunting and please don?t forget to rate this post.
