Chapter 1414-16MEMO:The height (position) of the primary and transfer charging wires may be ad-justed by turning the screw found at the rear of the charging assembly. A fullturn of the screw changes the position of the charging wire by about 0.7 mm.14.6 Fixing System14.6.1 Adjusting the Lower Roller Pressure (nip) 0010-9324iR7105 / iR7095 / iR7086The nip width must be as indicated in figure; if not, adjust it using the pres-sure adjusting nut.F-14-31a and c are points 10 mm from both edges of paper.T-14-3a. Generating Output for Nip Width MeasurementWait for 15 min after the copier ends its warm-up period; make 20 A4 copies,and measure the nip.1) Place A3 copy paper in the manual feed tray.2) Make the following selections in service mode to generate output:COPIER > FUNCTION > FIXING > NIP-CHK.The A3 paper will be picked up, and a copy like the one shown in figure willbe delivered.14.6.2 Points to Note When Mounting the Fixing Heater0010-9623iR7105 / iR7095 / iR70861. Do not touch the heater surface.2. For both heaters, mount so that the side with the longer heater harnessis toward the front.3. Viewing from the front of the fixing assembly, mount the main heateron the right (for 200V model, 1150 W; for 208V model, 1220 W; for230V model, 1185 W) and the sub heater on the left (for 200V model, 565W; for 208V model, 600 W; for 230V model, 645 W).4. Viewing from the rear, connect the right side of the faston of the heaterat the rear to the main heater, and connect the top side to the sub heater.Height of the Fixing Inlet GuideF-14-32Do not loosen the fixing screw on the inlet guide, as you will have to adjustthe position of the inlet guide if you remove the inlet guide base. If you mustloosen it, be sure to adjust the position of the inlet guide afterward by refer-ring to the index on the fixing assembly.14.7 Electrical Components14.7.1 After Replacing the Hard Disk 0010-9327iR7105 / 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.14.7.2 After Replacing the Main Controller 0010-9328iR7105 / iR7095 / iR7086Before Starting the Work (backing up the data)If possible, perform the following:- Using the SST, download the data stored in the RAM of the main controller.TransferDimension Measure with upper and lower rollers fully heatedb 200 V: 9.0 -/+ 0.5 mm,208/230 V: 10.0 -/+ 0.5 mm| a-c | 0.5 mm or lessHeight of charging wire9.0 0.2mmFeeddirectioncaMiddleof paperbA3 paper5.8mm(reference only)5.8mm(reference only)Fixing screw Fixing screw
