It could be that the cartridges are not inserted properly in the carrier or just needs cleaning. Try to remove both cartridges from the printer and manually clean the nozzles. You may refer to this article on How to Clean the Print Cartridge Nozzles and Contacts Manually. Then reinsert one cartridge first and close the cover. If no error appears, reinsert the other cartridge. Replace whichever cartridge is causing the error. You can also try the Clean Cartridge function on the printer by pressing the Setup button -> Maintenance -> Clean Cartridges. It will then print the clean nozzles test page. If error continues, replace the faulty cartridge.

The MFC-9840 manual says that this code is reporting a mechanical error.
Try to reset your machine in maintenance mode:
menu * 2 8 6 4 (within 2 seconds)
91 and then 99 to exit service mode.

Brother's suggestion:

Turn off the machine's power switch and then

turn it on again. If the error message continues

leave the machine for several minutes and then
try to print, copy or scan again

Unplug the printer from power cord.Press and hold the "menu" button, then plug the device.You'll see on the LCD screen a "machine error" code.If this code is 40,41,49 or 4F the print head is defective.If the
error is 50 or 51 there is error in Purge unit and printer require service.If the error is 48 - defective print head cable or circuit board.If the error is 46 the waste ink tank is full.Follow this:
1. Pres 'menu', 'mono start' then 'menu' one by one...
2. Press the arrow up or down to go to 'maintenance 80'.
3. Press 'mono start' several times to go to 'Purge'. Finding the PURGE will show some numeric value
which is Iassume the number of times the printer had cleaned.
4. Press 'arrow up' key and scroll for number "2" then press "set".Do the same for numbers 7, 8 and 3.
After you have entered this combination, the purge numeric value will be reset to 00000.
5.Restart printer

You manually rotated the aluminum drum? Since you did that, I would suspect you have the print head wiper blade stuck between the drum and print head. The code you are getting it caused by the print head not being able to move freely.
The jamming is probably due to a bad registration clutch. Common failure on that machine.
You can go to Xerox.com, there is under documentation and drivers a parts list for that machine. You can reference the wiper blade and get the clutch part number there.
Let me know what other information you may need. I will be glad to help you get it running again.

An error has occurred in the printer. The number of flashes indicates the type of error, as outlined below. Check the cause and take the appropriate action.
Two flashes: Out of paper or paper feed error
Replace the paper correctly and press the RESUME/CANCEL button.
Three flashes: Paper jam
If paper has jammed in the printer, clear the jam, replace the paper in the printer correctly and press the RESUME/CANCEL button.
See Paper Jams
Four flashes: Empty ink tank
If you press the RESUME/CANCEL button, it will continue printing with an empty ink tank. However, when printing is finished, replace the ink tank immediately. If you continue printing with an empty ink tank, it will be a cause of trouble.
See Replacing an Ink Tank
Six flashes: No print head installed
Install a print head.
Seven flashes: Defective print head
Contact a Canon service representative.
Eight flashes: Waste ink tank almost full
The printer has a built-in waste ink tank for the ink used during print head cleaning. Eight flashes indicates that the waste ink tank is nearly full. Press the RESUME/CANCEL button to cancel the error so you can continue printing. Before the waste ink tank becomes completely full, contact a Canon service representative.
Note
Canon recommends to call for service as soon as this error occurs. Once the waste ink tank becomes completely full, printing will no longer be possible.
POWER lamp flashes alternate green and orange:
An error that requires contacting a Canon service representative may have occurred.
Turn the printer off and unplug the printer from the power supply. Plug the printer back in and turn the printer back on.
If the problem remains, contact a Canon service representative.

I honestly don't know where you could get a manual. Other then try googling "the parts drop" and calling them. Talk to Britt.
Normally that print block is sticky or the cleaning blade is stuck to the print head causing that error.
