No need for part necessarily

MFC-5440CN saved from the tip!
"Unable to Clean" message - found TrickyDicky's sltn 4 for various printers.
Went into maint mode as per sltn 4 - verified error 46.
"The user can establish the internal Machine Error Code as follows: pull the mains cable out of the machine (power off), hold down the Menu/Set key, re-insert the mains cable into the machine (power on). The internal Machine Error Code will be displayed."

Keyed in 80 - stepped through the items with "down" key and located Purge Counter.
"Press the 2, 7, 8, and 3 keys in this order to reset the purge count to zero
Press the Stop/Exit key to return to the initial stage of the maintenance mode.
Press the 9 key twice to return to the standby state."

This worked brilliantly - no need to tamper with any parts of the printer. Purge Counter reset did it all. Fully functional printer.

Thanks TrickyDicky for info on verifying the error code and purge reset

SOURCE: scanner bar will not reset, error "unable to Init. AF"

the problem might be the connection from the mother board of the printer to the scanner maybe due to lost contact and the ribbon was broken you might just have to reconnect it or it might be broken and need replacement

SOURCE: i have an error called "unable to Init. E3". how do u fix this?

Go to menu, network, restore factory default. The printer will restart. Then reset the WLAN per your home connection.

Your Ink Absorber box is full. The machine cleans its print nozzles by blasting them out with ink; it collects that waste ink and pumps it into a plastic box filled with thick, felt pads. After a certain number of cleaning operations, it decides it's not safe to squirt more ink into the box and gives this Error 46. Replacing the ink absorber box and flushing box and resetting the purge counter is fairly complex. Maybe someone has instructions all typed out, but your best bet is probably to take it to a Brother tech.

There are several issues that pertain to this code, including a service update. If your printer is still under warranty – visit your local ASC, find one here, this issue is covered! First off, the Service Update, the encoder strip needs to be cleaned with a lint free cloth. The encoder strip is responsible for relaying the position of the print head to the main pcb. If the encoder strip gets dirty, many different problems can occur. The encoder strip is exposed, which allows grease, paper dust, finger prints, ink, etc. to get onto the encoder strip. (The white strip when you open the scanner cover)
If the machine still errors, the encoder strip needs to be replaced – Part Number LS4467001
If the machine still errors, replace the carriage PCB assembly – Part Number LS6543001
If the machine still errors, replace the Printhead – Part Number LK3211001
If the machine still errors, replace the Main PCB assembly – Part Number LT0284011
