Question about Brother MFC 6800 All-In-One Laser Printer

1 Answer

Paper feed occasionally gets stuck 1/3 way through.

A few days after I replaced the drum, the paper gets stuck 1/3 of the way while passing through the paper feed. I have to remove the paper jam and try atleast a few times before the paper feeds throught correctly.

I did notice that the paper never reaches the drum. It seems like the rollers (not sure of the technical term) near the paper feed stack area does not take in the paper all the way through.

Any suggestion is appreciated.

The paper keeps jamming in behind the drum, and when removed, the papper is heat damaged in my brother mfc9450cdn

The paper is clearly not feeding properly, that's why it's heat damaged when you open up the unit.

The 2 most likely causes are:
1. Paper path and/or printer mechanics are blocked by something foreign - this could be a stray piece of paper (simple fix) or a piece of the printer that has broken off (not so simple).
2. Something has broken/malfunctioned such that the mechanism that feeds the paper is either not feeding any more, or is blocked somehow.

Tough break if the cause is item 2; you'll need to have the printer serviced (if it's worthwhile based on age/condition), or replaced.

To determine if you're lucky and the cause is item 1, unplug the printer from power, remove the toner cartridge(s) and remove the drum (protect the drum from intense direct light). Visually inspect the inside of the printer to ensure every scrap of paper or clump of toner is cleaned out. Also inspect the drum/toner cartridge for damage and to ensure nothing is stuck on either - clean as necessary.

One final thought - if you're using paper that's too thick for the printer to handle, this can also happen. In that case, of course, clean up the printer (as advised above) and use normal paper. Refer to the printer documentation to see what weight of paper is compatible with it.

Good luck,

Asked me a paper was jam

You didnt wrote where it is the paper jam.
Here are few common jams:
  1. if the paper jams in fuser unit, do/check next:clean the paper delivery rollers ( when you open left door its two roller on axis beneath the drum ), check the sensor flapper beneath the drum unit if its worn out you need to replace it, does the paper comes out like bent in the roll? open fresh pack of the paper and try again it could be moisture fault.
  2. the paper stucks in pickup section, clean the paper pickup, feed and separation roller, to do that remove paper drawer and you will be able to see the rollers on left inner side.Open the lower leftside door and check the paper senzor in the middle.You can apply some wd40 on spring of flapper or on left side bushing.
  3. dadf jam, check for any paper leftovers and clean the paper pickup and feed rollers
Hope that helps!

Paper feed problem - uneven feed

If you don't see anything stuck down where the paper starts in, you might have a bent frame. What I see the most on this model is the center gets smashed down by luggage piled on top or tools and it bends the frame so paper can't pass thru. I have been able to rescue a few of these but usually you need a new print engine that runs around $169.00.

Paper jam on initial feed

It sounds to me like your pickup rollers are worn. You should order a new set and replace them. That should solve your paper jam issue.

Paper Jams and Black Streaks

I would suggest calling a professional on this one. The jamming problem you are describing is probably the rubber feed tires in each tray that pick the paper up. They need to be replaced. If you could get the parts, you MIGHT be able to do this...however....the other problem is much more involved. It could be that you only need a drum cleaning blade. This is the blade that cleans the unused toner from the drum. But it could also be the drum itself, the developer, or the fuser. And it sounds like it could use a good vacuuming on the inside. Do not clean the drum. If the drum is still in good shape, cleaning could change that. Drums are very prone to scratch. I would call a professional....tell him or her: the model of the copier, and to bring feed tires, a drum cleaning blade, and a vacuum.

Hope some of this helps,

Paper a misfeed

not sure if you are talking about two papers jammed in different locations or at different times?

first thing would be to clean the tires that pick up the paper, if too smooth then replace. sounds like a timing issue.paper getting stuck halfway in the fuser c(if no other paper jammed) can be Seperation is off causing the paper to rise onto the drum creating a time lapse, paper tansport belt (in the machine after the drum) is not turning ok, or as simple as wrong size paper Letter in machine but says Legal 8 1/2 x 14

Our copy machine keeps flashing E2. There is no paper inside the machine.

Remove the toner and drum cartridges. Using a flashlight, look inside the front of the printer. At the rear of the cavity there are two large rubber rollers. On the floor, about an inch to the right of the rightmost roller, there's a tiny black plastic feeler that's supposed to protrude from a slot in the floor and be pushed down by paper as it feeds through. Occasionally it sticks in the down position, causing the printer to think there's a paper jam. Running a finger over it usually unsticks it so it will pop up where it belongs. I usually flick it down a few more times to make sure it's free to pop pack up. I guess the spring tension, light by design, is sometimes not enought to overcome friction.

Copier down

Understanding how an image (copy) is made might help.
The drum goes thru a Basic process like this; charge,exposure,transfer,clean.
the paper only comes into play during the transfer stage. Since the drum has a static charge the paper gets attracted to the drum and needs to move at the same speed as the drum. After a small distance the paper has to be repelled from the drum with the print (sometimes called Detack), this can be accomplished by a Detack wire or a reverse of polarity applied to the paper.
If this doesnot happen paper stays on drum (jam).
So you need to see if the jam you remove has any ink on it, this would indicate a transfer issue maybe a detack problem.
If it is clean (never reaches the drum) then a paper feed problem is indicated.
Now you need to understand paper!
Some paper is long grain other is short grain. This is what gives the stack of paper a curl as you hold it by the edges (most paper has an arrow on the wrap telling which way to run paper (it means curl up / curl down basically). The problem with grain is usually when some cuts down 11 x 17 paper to save money to give you 8 1/2 x 11.
How do you tell grain fold paper in half long edge to long edge run your fingers down the edge if it is smooth you have long grain. Most copiers feed the long edge therefore long grain is what you need . If when you fold in half the edge is rough, then fold another top to bottom if seem is smooth you have short grain, This works better on top edge feeding copiers / printers, these are unusual since most they are slowest (mostly diazo printer).

Since you seem to have problems early make sure you remove paper every night and store flat, note the curl direction beacuse if when you put it in in the morning it might change curl (teacup).

Some times old machine use rubber rollers to start initial fee, these you could try to clean with some finger nail polish remover. This will eventually dry out the rubber but if it helps then maybe you only need to replace the rollers.

That was a quick lesson hope it helps.

More than likely you have bad feed tires in the tray you're pulling from or if the drum unit is stuck there probably is paper jammed up in the unit.  Replace you feed tires and check your drum separation claws when you are able to get the drum unit out.
