Number: AR-153E-007 Date: June 2003

Subject: Parts Change To The MCU PWB (L1-00 Trouble).

1. Model: AL-1215/1530CS/1540CS/1551CS AR-153E/157E/153EN/157EN

2. Symptom: The Copy Lamp is intermittently turned off which may cause L1-00

trouble.

3. Corrective Action: If L1-00 trouble is experienced, replace the resistor R239 to the new style (5.6k ohm type).

4. Note: Check the condition of transistor Q108 (PN: VSKTA1281++-1) when troubleshooting the MCU PWB after replacing R239.

MCU PWB 1

Note 1: When replacing the MCU PWB on the AR -153E/157E/153EN/157EN make sure to look at the Serial Number Plate on the rear of the machine to determine if you have an “E”

model or “EN” model. The MCU PWB’s are different for these models. On the “E” version Connector CN106 is 4 pins and on the “EN” version CN106 is 10 pins.

Note 2: On machines produced from January 2003 production resistor R239 has been changed to the 5.6k ohm type so the new MCU PWB’s will have the new style resistor.
