This model of printer has a bad reputation for leaking cartridges.
Depending on the type of splotches this can be one of two things.
1) The Cartridge is leaking causing sprays of toner on the page. Replace the cartridge or return it to where you got it for replacement under the cartridge warrantee.
2) The drum may have marks on the surface causing dots to appear on the page. This is shown by the marks repeating down every page. Normally repeating 3-4 times on the page. This can be cleaned by a professional by taking it in to one of several cartridge re-manufactures in your area. or if you are brave you could do it yourself using Isopropal alcohol and a cotton ball but do this away from light as Ultraviolet light will destroy your drum unit requiring you to replace it.

SOURCE: constant paper jams

For the accordion jam, open the back panel. You'll see two screws on the left and on the right. Unscrew them and try to take out the part with the small plastic roller out. Clean the rollers. Then you'll see another rubber roller on the ceiling of that part. Clean them with a damp cloth and rubbed them gently. Then screw back the part you took out and close everything back up. That should clear the jam.

There's probably something wrong with the drum unit. I would check the manual on how to change the drum unit. Good luck!

What is the amount of magnetic Powder to be developed in the Fuser Section?


None. It is electrostatic attraction.
It varies from each type of laser printer.
Most printers will specify a total number of pages printed from a laser toner cartridge rather than give an actual amount of toner per page. Which I feel would be more likely to be an average value.
Due to the amount of toner being used per page varying on the number of actual pixels that are required - a black dot or a color dot. If a colour dot is required Three toner colors may be involved to get the color required. Where there is a white dot no toner is required.
It really depends on what image is being rendered onto the paper on each different page image print onto the paper.
Color photos use more toner as more of the page is color than when using black and white !

There is a paper jam...how do I unjam it


Hi dorothyhover,

Here's how you would clear paper jam from your Brother HL 1430:

1. Remove the paper cassette completely from the printer.

2.
Pull any jammed paper up and out of the printer.

3.
Open the front cover and remove the drum unit assembly.

4. Pull any jammed paper up and out of the printer.

Do not remove the drum unit assembly with additional force at this time if you cannot remove it easily. Instead, pull the edge of the jammed paper from the paper cassette.

5. Open the rear cover and pull the paper towards the back of the printer, the fuser may get dirty with toner powder and may result in toner scatter on the next printed page or pages. Print a few copies of the test page until the toner scatter on the printed pages clears.


6. Close the rear cover and install drum unit assembly, close the front cover.


Hope it helps.


Thank you for using Fixya.

Printed pages are smeared with black


Sounds like a bad toner, or possibly the scanner is dirty. If you look where it pulls the paper through it can have a small speck, but since its on the scanner tself it will put black lines all the way down the paper.
If its larger and smeared the Toner itself is probably bad and you need a new Toner Kit, should come with new rollers and a new cartridge as well.

Prints dry colour powder on paper


You aren't fusing (melting) the toner to the paper. The probable cause for this is having the "envelope feed" levers in the "envelope", or up, position. This leaves a wider path for the paper, which does not allow the toner to be fused onto the paper properly.
The envelope feed levers are the two small green levers at the rear of the printer, one on each side, that are visible when the printer's top is lifted.

OKI Laser Printer C5300 printing on paper with black flecks


IF you are using after market black toner then we found your problem. Putting a real toner on now wont help cause dodgy toner is now in the drum, you need to replace Black drum and use real toner. If you are using gen OKI toner, then just replace the Black (K) drum.

Clean led head and these printers dont need a teco, they are designed for wearing parts to replaced by operator ie Transfer belt, fuser, drums and toners.
