Hi,
1) what kind of hdd failure? Did copier report error code like E602-0003, or? When the hdd error occured did the service exchange HDD with new one and upgrade the system. Other thing, but not mostly likeble, check the current in el. insert.
2) Wich kind of problems? Did the copier reported E000, E001, E002, E003,..., is there was smudged copies, paper jams,..., how did you solve the problem? Did the service replace fixing film unit, or complete fixing unit? Do you have enough air flow around the copier, is the copier beneath the air conditioning device, is there any air draft,...?
If you want you can contact me on
