[1] Adjustments

General

Since the following adjustments and settings are provided for this model, make adjustments and/or setup as necessary.

1. Adjustments

Adjustments of output voltage (FACTORY ONLY)

1.Install the power supply unit in the machine.

2.Set the recording paper and document.

3.When the document is loaded, power is supplied to the output lines. Confirm that outputs are within the limits below.

TEL/LIU PWB

POWER SUPPLY PWB

CNLIUCN2

CNLIUACNPW

CONTROL PWB

2. IC protectors replacement

ICPs (IC Protectors) are installed to protect the motor driver circuit. ICPs protect various ICs and electronic circuits from an overcurrent con- dition.

The location of ICPs are shown below:

CNLIUACNPW

FU100

CONTROL PWB (TOP SIDE)

(1)FU100 (ICP-S07) is installed in order to protect IC’s from an over- current generated in the motor drive circuit. If FU100 is open, replace it with a new one.

4.Method of release of starting lock up by Battery Reset

(1) Summary

There is a possibility of release of the lock up by reset the signal BATRST of CPU (FC100), if it lock up when you turn on the power of the set in UX-258 series. We inform you of the method of release.

(2) Contents

When you turn on the power of the set without EPROM by your mistake, if you turn off the power after, turn on the power with EPROM again, the set don’t start.

In this case, before you judge the cpu (FC100) is wrong, you need to confirm the release of the lock up by reset the signal BATRST. and unknown origin in the same way.

Method of the reset of signal BATRST

Short the between leads of the capacitor C5 on the control PWB, X2961-81 in the state of POWER OFF.
