Normally it is fro corrupt data or bad cables.
49.xxxx error explain.
A critical firmware error has occurred that
caused the processor on the formatter to
abort the operation.
This type of error can be caused by invalid
print commands, corrupt data, or invalid
operations.
In some instances, electrical noise in the
cable can corrupt data during transmission
to the printer. Other causes include poorquality
parallel cables, poor connections, or
specific software programs.
Sometimes, the formatter itself is at fault,
which is usually indicated by a 79 Service error
Left corner is folded down on page
Sounds like an issue with the feed rollers. The roller on the left side might be hung up and is causing the corner to fold over when the paper is pulled through. I would try checking the feed rollers in either the actual tray or the back of the printer. Another thing to check is the other tray (the manual one). Does the paper fold? this should help you narrow down where the problem lies.
Replace the dc controller PCA
Remove the right side cover, top cover, remove the formatter board and you will see the controller board. Don't have to label the wires, each one goes into its own connector.
Error 50.40
50.4 is a problem with the fuser, likely a bad heating element.
