Other than that setting, double-check the type of paper to which you're printing.  While many paper types currently available are multipurpose, some are still made specifically for Inkjet or specifically for Laser printers.  Inkjet-specific plain paper may not print correctly in a laser printer.

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?

For the MF Drivers, you can adjust color/grayscale quality on the Quality tab.  This can be used to adjust the brightness, contrast, and gamma.

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.

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

Set point indicators are provided for pass-fail testing. The gauges are overload protected to 150% of capacity, and an analog load bar is shown on the display for graphical representation of applied force. An ergonomic, reversible aluminum housing allows for hand held use or test stand mounting for more sophisticated testing requirements. Series 3 digital force gauges are directly compatible with a wide range of test stands, grips, and software. The gauges include MESUR™ Lite data acquisition software. MESUR™ Lite tabulates continuous or single point data. One-click export to Excel allows for further data manipulation.

ALL of this began after I downloaded the Canon Driver updates # 1/6/20 yesterday.  I think I will just call the help line and sit on hold for an hour.

Web-based content often is not actually black and white, but rather various shades of colors to produce a more pleasing and properly contrasted image.  When printing to the MF743Cdw, some of those finer details are lost due to the lower resolution of the printer, and some of what appears to be black will be printed lighter, in black and white or grayscale printing, due to actually being a dark shade of another color.

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.

Canon provides drivers for this printer at the MF745Cdw Drivers & Downloads page.  You're free to use any other drivers, though we're only able to help with the drivers we provide.

I tried this setting but it didn't help. However, the details of this function indicated it would change the operation when a new cartridge was inserted.  Of note in my case, printing black is dark/correct when I print a document through MW Word so the printer/toner appears to be capable of operating correctly.  It's printing other things, like webpages, where the black is light gray.  I've selected B/W printing, but black text is still quite light.  So this seems like an incorrect default somewhere.  Let's try addressing this from the other direction?  What setting would I change if I wanted to lighten black text?  Also, I've seen multiple posts that the printer driver for this printer is terrible.  What I'm seeing is a very full-featured offering (maybe too many?) but what is the correct driver for this printer?  Thanks!

If this problem is occurring out-of-box, try enabling the Reduce Faint Print After Replacing a Cartridge option.  The menu map for that is:

When printing web-based content, try to use a "Printer friendly" version, and, if possible, change it to black and white before printing.  Most current operating systems will allow you to Save as PDF; setting Black and White or Grayscale for Save as PDF will allow you to see the black and white before printing.

My printer is printing  navy blue as purple.  I read on google that I may need to 'calibrate' the cartridges, but it did not say how to do that.
