I found a solution to the problem of black suddenly starting to print light grey,
and it doesn't involve downloading the printer manual or changing your toner cartridge!
From Windows 10 (probably similar for other versions), go to
Printers and Scanners/
select your printer, then click on 'Manage'.
A Properties dialog box opens. In the General tab, select Preferences
A Preferences dialog box opens. In the Graphics tab, under Image Adjustment Mode,
select ICM Adjustment System.
Apply/ OK/ OK
Try printing a test page
You can click the link below to download the online manual. The manual provides information on cleaning your computer as well as other helpful information on maintaining your printer.

I having this same problem.
We have tried everything in the manual.
All the colors print fine. Only black is grey. We have replaced the black rober 3 times.
We use Dell toner.
We have the SAME problem!
It happened within maybe one hour, when we printed several dozens of pages, and the printer driver was set to only print in black.
The black colour on the printout turned more and more from black to gray, now it is near to invisible.
Of course we also tried:
- changing the toner cardringe
- updating to the latest firmware (we succeeded)
- cleaning the CTD sensor
- removed all toner cardriges and cleaning those "wholes" beside them.
- trying whatever is possible with the "DELL C1765 Toolbox"-software (windows 8)
Nothing helped. Very frustrating!
We googled and realized: There are other DELL customers with the same problem. So I think there SHOULD be some solution, right?
So please answer.
Also having the very same problem and the printer is just out of warranty so I can't just send it back to the vendor.
Replaced the black toner cartridge twice.
Also tried all the maintenance menus (cleaning, etc.), used the blue cleaning rod, etc. Nothing works.
In the manual there is a referenace to 'Toner saving mode', however, this does not exist in printer preferences in the driver on my system.
Can anyone help?
Very strange that we are all having the same Problem. Me too with the c1765 of a client.
Wondering that the support doesn't help with this issues. I recommended a dell Printer because I didn't want my client become victim of built-in obsolescence. I'm not feeling confident anymore.
The problem is that it happened after and not in the period of warranty.
