Question Brother MFC9130-CW color quality issue

[alexmart]

I'm having issues with my Brother MFC9130-CW printer.

I have changed the drums, the toner cartridges are new, I have cleaned the LED heads and the belt.

I'm now out of solutions. My test print sheet is A1, however as soon as I'm printing a document color is faded.

Here is the result when I'm trying to print a document : https://ibb.co/WyTRcvH

I have installed the latest driver also

Thank you for your help!

My test print sheet is A1

The manufacturers product page states A4 as the largest paper size it can handle. This doesn't explain the faded color, but could cause problems.

How long has it been since the drum unit and belt unit were changed out? Cleaning the belt, if not done properly, will absolutely degrade image quality as will 1 or more drums that have either aged out or otherwise reached the end of useful life.

Sorry I meant A1 for perfect, not the format

Both a few days ago, and image quality is still exactly the same berfore and after

That being the case then you've got a mechanical problem. The streaked side is lower than it should be. This requires a visit to the shop for an evaluation. This is not user fixable.
