How do I mirror/reverse print on a cannon mx410?

Canon does not specify what 6000 means but they do recommend unplugging the machine for at least three minutes to clear problems with the printer and to reset the operation. I would try this. Here is the address of the current manual for the printer:
https://www.usa.canon.com/internet/portal/us/home/support/details/printers/support-inkjet-printer/mx-series/pixma-mx410?tab=manuals

try differnt paper, use cannon manual to see how to maintan the rollers

On the flat bed it faces down, on the ADF place it face up.

When you click print, and IF a Print Window opens, then it should allow you to click a button on that window to change the Print Properties. There should be a choice for "reverse order" and you just need to unclick that choice.

reboot both pc and printer, you reinstalled printer drivers?, try restarting your print spooler service, try on another machine to confirm where the problem is with pc or printer.

Scanned document is saved with a file name and in a directory such as desktop. Then attache the file name to an email you send to someone.

go to this link http://www.manualowl.com/p/Canon/PIXMA-MX410/Manual/68071 and download the manual i dont think u can just read one without downloading it. So just go to the link above

For me on my Cannon MX410 with a "paper Jam" light displayed this WORKED!! The absolute BIZZARE thing was after I went and through the described procedure above and rebooted and tried to print the 1st page that came out had a "crushed" ****-roach on the 1st page! So I didn't have a paper jam,...but a
ROACH Jam. :) I told my wife, Humm pest service not workin I guess! It errored out again, but simply unpluggingUSB and power cord (not the steps described for the Print Spooler) it prints fine. SO saved me buying a new printer which was just 6 mos. OLD and FINE by me! So THX, Vikram Kumar Thumu!

how do I scan with my cannon mx410

Sounds like you have a bad drum. If a mirror was dirty, all prints would be light.
