Imageclass MF743Cdw prints too light. How to get it darker?

My new (bought in October) Imagelcass has yet to print black in full black. It's very light, almost greyscale.  Color prints fine but the black is more of a grey.  I can adjust print settings when making copies, but can't find a way to make it "print" darker.  I use a PC, not a Mac.  Suggestions?

How to fix the “lighter looking” / slightly “washed out” printing of a Canon MF740 Series laser printer (Canon Color ImageClass MF743Cdw).

 

I noticed the brand new Canon MF743Cdw was printing what I would call “washed out” Color. Even on Black/Text only prints, it looked almost “Lite-Brown” or like some sort of Lighter Grayscale instead of a “Deep True Black”. It was very noticeable compared to several Canon Color ImageClass MF730 Series / MF733Cdw printers I had previously installed and configured.

 

To fix this…I followed this procedure and now the MF740 Series / MF743Ddw is printing like expected…like a champion with full vibrant Color and great rich deep Blacks when printing either B&W or Color.

 

Three (3) Steps to Great Color & Deep Blacks –

  1. Clean Fixing Assembly -
    Go to the Home Screen  >  Menu  >  Adjustment/Maintenance  >   Maintenance  >  Clean Fixing Assembly  >  Select ‘OK’  >  Then, Select ’Start’ (in the lower righthand corner of the Printer Display, and let it do its thing).
  2. Correct Print Color Mismatch -
    Next, go to the Home Screen  >  Menu  >  Adjustment/Maintenance  >  Adjust Image Quality  >  Correct Print Color Mismatch  >  Select ’Start’ (in the lower righthand corner of the Printer’s Display, and let it do its thing).
  3. Auto Adjust Gradation - Full Adjust - (This is a more robust sequence than the initial Startup Color Adjustment when the printer was first turned ON.)
    Go to the Home Screen  >  Menu  > Adjustment/Maintenance  >  Adjust Image Quality  > Auto Adjust Gradation  >  Full Adjust  > Select ‘OK’ (it will list 4 Steps)…
    1. Print Image 1 for adjustment.
    2. Scan the printed Image 1 for adjustment.
    3. Print Image 2 for adjustment.
    4. Scan the printed Image 2 for adjust.
      Select ’Start’ (in the lower righthand corner of the Printer’s Display, and follow the on screen instructions).

 

This did the trick for me, hope others find it helpful, enjoy! 🙂

I completed this sequence, the first page it prints is a single vertical black chevron but the printer never says to scan this page, did I miss something? Is this part of the sequence?

I'm a little late to the game here, but I've attempted to follow the steps provided to complete the suggested calibration / maintenance. But when I try to complete step 2 (Correct color mismatch) the printer attempts the sequence and I receive an error message that it's not able to perform the task... Any experience with this?

Thanks for the help!

Thank you for your suggestion.  I have been contemplating beating my MF741 into a pile of plastic over this issue.  Seriously, my printer seems to be printing with great quality now.  I echo all of those who are mystified over the need to perform this process.  Why doesn't Canon put those instructions in the box if they can't figure out how to do it for us?  Haha, another mystery!

Glad it worked for you! 😇 Indeed one of the mysteries in life!!! 🤪

I can't perform any of the adjustments.  it says "Could not Perform Correction"  I see not issue when printing text but i tried printing and image and it looks like it is out of focus.  

what does it mean if it can't even perform the tasks listed above.

This did not work for me. However, after removing the printer from setup, I downloaded/installed the Canon driver from https://www.usa.canon.com/support/p/color-imageclass-mf743cdw.

The new driver from canon fixed if for me.

Hope this is helpful!!
