Question about Brother MFC-9840CDW Laser Printer
I am using a brother mfc-9840cdw and everything we print comes out low on red and in a pastel color rather than the true color represented in the file. We have tried resetting to the default settings, replacing all the toner, cleaning the scanner windows, and changing other settings previous to returning to the default settings. We are at a loss and any help you could provide would be much appreciated.
a 6ya expert can help you resolve that issue over the phone in a minute or two.

If this only happens when you are copying.
1. Your scanner glass is dirty. Open the lid, use windex to clean the flatbed. Look on the left side. You should see a strip of glass, with the scanner sitting under it. This strip is used when the document feed is being used. Make sure it is clean. Most common problem is getting a little whiteout or the sticky residue from scotch tape on this glass, which causes lines down your copies.
Clean it with alcohol which will dissolve the sticky stuff and the whiteout.
If this does not solve the problem, the CCD scanner in your machine might be going bad.

To get every bit of toner powder out of the cartridge, first remove the toner unit from the drum assembly. Second, find the little circular window on the right-side of the toner cartridge. Third, place a piece of black electrical tape over the clear window, cannot be clear tape. Fourth, re-install the toner cartridge into the drum assembly. Last, put the complete unit back into your printer. This worked for me.
