3) Execute Utility Menu > CALIBRATION > COLOR REGIS.ADJ.

5.1.1.3 After Replacing the Video Controller PCB

i-SENSYS LBP5300
In the case that the video controller PCB has been replaced, remove EEP-
ROM (ICS11S) from the old PCB and mount it in the new PCB.
0015-2314
Execute the following procedure when replacing the video controller PCB.
1) Turn on the power supply of the host machine.
2) Execute Option Menu > Utility > Out-of-Register Colors Correction in the
status window.
3) Execute Option Menu > Utility > Calibration in the status window.

5.1.1.4 After Replacing the Video Controller PCB

/ i-SENSYS LBP5360
In the case that the video controller PCB has been replaced, remove EEP-
ROM (ICS11S) from the old PCB and mount it in the new PCB.
Execute the following procedure when replacing the video controller PCB.
1) Execute Service Mode > Function gr. > CLEAR DCON.
2) Turn off/on the power supply.
3) Execute Utility Menu > Status Print.
4) Execute Utility Menu > CALIBRATION > COLOR REGIS.ADJ.
Execute the same procedure as the one for replacement of the video control-
ler PCB also when EEPROM (ICS11S) was replaced.

5.1.1.5 Replacing EEPROM (When E747-000 occurs)

i-SENSYS LBP5300
1) Replace the video controller board or EEPROM (IC2S).
2) Turn on the power supply of the host machine.
3) Execute Option Menu > Utility > Out-of-Register Colors Correction in the
status window.
4) Execute Option Menu > Utility > Calibration in the status window.
Memo
When EEPROM was replaced, a new USB serial number in EEPROM is as-
signed. The number of the printers on PC increases when USB is connected.

5.1.2 Adjustment of Fixing System

5.1.2.1 Checking the Nip Width (fixing pressure roller)

/ i-SENSYS LBP5360 / i-SENSYS LBP5300
Do not check the nip width in wrong order. The fixing sleeve breakage may
occur, if you do not follow the procedures below.
An incorrect nip width may cause the faulty fixing. Check the nip width by
following the procedure below if poor fixing image defect occurs. Replace
the fixing unit if the nip width is out of specification, since the nip width of
the fixing unit is not adjustable in this printer.
1) Make an all solid black print of A4 or Letter size using an EP cartridge
same as for this printer, and take the print to the customer's site.
2) Place the solid black print, with the printed side facing UP, in the cassette
of the printer.
3) Press the test print switch.
4) Open the upper cover as soon as the leading edge of the paper appears in
the delivery slot. Leave it for ten seconds.
5) Turn OFF the printer and take fixing unit from the printer. Then take the
paper out from the fixing unit.
6) Measure the width of the glossy band across the paper and check that it
meets the requirements as shown in Figure.
- Center (a): 8mm +/- 1mm
- Difference between right/left and center (a-b, a-c): 0mm to 1mm
- Difference between right and left (|b-c|): 1.5mm or less
