Missing lower rear door:
Future design of the lower rear door will no longer have a cover. The images below show the comparison between the current and future design.
Current MX81x
Future MX8x without lower rear door
Note:
If you are installing a new FRU part on an older printer that still has the lower rear door, the door interlock sensor will need to be disconnected or removed.
