5.3 Unit Level Troubleshooting

The information for this section is the same as for the FX-2170 except
for the point below:

Point: Main board number

5.4 Repairing the C166 PSB/PSE Board

See LQ-2070 Service Manual.

5.5 Repairing the C276 Main Board

This section provides instructions to repair the C276 Main Board
assembly. It describes various problems, symptoms, likely causes, and
solutions. The checkpoint column provides proper waveforms,
resistance values, and other information for each component of C276
Main Board.

NOTE: This information is necessary only for servicers who repair to

the component level. Servicers who repair to the unit level
(including all servicers in the U.S.) can ignore this section.

Problem

Cause

Checkpoint

Solution

The printer does
not operate at all.

Reset IC15 is
defective.

Check the voltage
waveforms of the VCC signal
(CH1: IC15 pin 2) and VOUT
signal (CH2: IC15 pin 5)
when power is turned on.

Replace IC15.

The PROM
(IC5) is not
selected.

Check for a change in the
signal from HIGH/LOW at pin
24 of IC5.

Replace IC5 (or
replace the main
board).

The PSRAM
(IC3)

Check for a change in the
signal from HIGH/LOW at pin
22 of the IC3.

Replace IC2 (or
replace the main
board).
