1.4 Cautions for FIP Use
1) When troubleshooting according to the FIP, normal PWBA MCU, PWBA HVPS, PWBA LVPS,
FUSER ASSY, TRANSFER ASSY and so no may be necessary for isolation of failed parts. Pre-
pare them in advance.
2)
In the initial check according to the FIP, check only items which can be simply checked.
3) In the initial check according to the FIP, check the constitutive parts of the major check parts and
related parts, as well as major check parts.
4) When working with the printer, be sure to remove the power cord unless otherwise required.
5)
Connector condition is denoted as follows:
[P/J12] -> Connector (P/J12) is connected.
[P12] -> Plug side with the connector (P/J12) disconnected (except when attached directly to the
board).
[J12] -> Jack side with the connector (P/J12) disconnected (except when attached directly to the
board).
6) [P/J1-2PIN <=> P/J3-4PIN] in the FIP means measurement with the positive side of the measuring
instrument connected to [2PIN] of [P/J1] and the negative side to [4PIN] of [P/J3].
7) [P/J1<=> P/J2] in the FIP means measurement for all terminals corresponding between [P/J1] and
[P/J2] based on "Wiring Diagrams".
8) In [P/J1-2PIN <=> P/J3-4PIN] in the FIP where voltage is measured, [P/J3-4PIN] on the rear nega-
tive side is always at the AG (analog ground), SG (signal ground), or RTN (return).
Therefore, after checking of proper conductivity between AGs, SGs, or RTNs respectively, the rear
negative side can be connected to the PIN of AG, SG or RTN instead of [P/J3-4PIN].
However, care should be taken not to confuse [AG], [SG], and [RTN] because they are not on the
same level.
9) When measuring the voltage at small connectors, use the dedicated tool. Handle the tool with care
because its business end is pointed.
10) When measuring the voltage, set the TRANSFER ASSY, TONER CARTRIDGEs and Paper Cas-
sette, close the COVERs and power ON unless otherwise required.
11) Numerical values in the FIP are only for guide line. Approximate values are acceptable.
12) In each step of the FIP, parts removal and other procedures implicitly required for the step are
omitted.
13) In the FIP, "Replacement" means the replacement of the parts that are considered to be the cause
of the trouble. Replacement of those parts means the replacement of the assembly part (HIGH
ASSY) that contain them.
14) Some of the instructions in the FIP are branched off depending on the specifications. Follow the
applicable instruction.
15) For some optional components, you may have to refer to the manual of the relevant component for
troubleshooting. Have the relevant manual at hand as needed.
