Chapter 44-19Be sure to remove the counter PCB before removing the hard disk, whichotherwise could hit the PCB and suffer damage.2) Remove the hard disk [1].- 2 screws [2]F-4-424.6.5.4 Removing the Hard Disk(up graded version) 0018-0408iR7105 / iR7095 / iR7086 / iR7095P1) Remove the counter PCB [1].- screw [2]F-4-43Be sure to remove the counter PCB before removing the hard disk, whichotherwise could hit the PCB and suffer damage.2) Remove the hard disk [1].- 1 connector [2]- 2 screws [3]F-4-444.6.5.5 Points to Note When Mounting the Hard Disk 0010-8743iR7105 / iR7095 / iR7086- When mounting the hard disk, fit the claw [1] found on the back of the harddisk into the opening [2] of the hard disk mounting plate; then, push it inhorizontally. If the connector of the hard disk is at an angle in relation tothe socket (on the main control PCB), forcing it in could well damage theconnector.F-4-454.6.5.6 After Replacing the Hard Disk 0010-8745iR7105 / iR7095 / iR70861) Formatting the HDDStart up the machine in safe mode (i.e., turn on the main power whileholding down the 2 and 8 keys).Using the HD formatting function of the SST, execute full partitionformatting. (For details, see the chapter on upgrading.)2) Downloading the System SoftwareUsing the SST, download the following: System, LANG, RUI, PS-FONT, OCR dictionary, SSL encryption key, SSL CA certificate, MEAPcontent.3) Execute the following service mode item:COPIER > FUNCTION > CLEAR > CA-KEY (Level 2)4) Turn off and then on the power.MEMO:Execution of the following may delete the keys/certificates used for encrypt-ed communications and the CA certificates used for authentication of exter-nal server certificates:- replacement/formatting of the HDD- replacement of the main controller PCB/initialization of the RAMIf a key/certificate for encrypted communications has been deleted, the con-trol panel screen will indicate a message to the effect that the key has beencorrupted: however, the key/certificate/CA certificate installed at time ofshipment from the factory may bebrought back by executing the following: COPIER>FUNC-TION>CLEAR>CA-KEY. If doing so has failed, use the SST to install thekey/certificate/CA certificate, and execute CA-KEY once again.Points to Note When Executing Service Mode Item CA-KEYIf the user has generated/added a key/certificate/CA certificate on his/herown, executing CA-KEY will also delete these files. Inform the user of this,and ask him/her to re-install them as necessary after the execution of CA-KEY.Points to Note About a HDD to Which System Software Has Been In-stalledIf you must use a HDD to which the system software for a different machine(thus a different serial number) has been installed, be sure to format it aftermounting it. Otherwise, the machine operation cannot be guaranteed.4.6.6 Video PCB4.6.6.1 Making Preparations 0011-4578iR7105 / iR7095 / iR70861) Remove the main controller box cover [1].- 10 screws [2][2][1][1][2][2][1][2][2][2][1][2]
