SUBJECT: BLANK IMAGE ON FIRST COPY / SC101
SYMPTOM:
The following may occur just after powering on the unit:
Copying
A blank image appears on the 1st page and an SC101 message is displayed.
Faxing A blank image appears on the 1st page and an SC101 message is displayed. However, the
transmission results are reported as being normal.
These symptoms are limited to the first copy after turning on the power. These symptoms may not occur
every time power is turned on, even on units that demonstrate this symptom.
CAUSE:
The Exposure Lamp does not generate sufficient light during the first copy. While making a copy, the
Exposure Lamp may be abnormally slow in reaching ready status. Therefore, the Lamp is not able to
produce the required amount of light within the given time period. The source of this symptom has been
identified as defective internal components in the Exposure Lamps that were produced in March, 1999.
SOLUTION:
The Exposure Lamps produced in March, 1999 were installed in some machines manufactured in March,
April and May, 1999. Please check the Exposure Lamp lot number by following the procedure outlined
below, on units that are listed in the UNITS AFFECTED area of this bulletin. If the Exposure Lamp’s lot
number begins with “39”, the Lamp should be replaced. The lot number can be found on the black lamp cap
on the rear side of the lamp. The lot number is also in black and therefore it may be difficult to read.
Procedure for checking the Exposure Lamp lot numbers (and replacement, if necessary):
1. Remove the Exposure Glass.
2. Slide the 1st Scanner to the cutout in the rear Scanner Frame.
3. Read the lot number printed on the Exposure Lamp cap.
4. If the first two digits of the lot number are 39, replace the Exposure Lamp (either Field Replacement P/N
A2829450 or New P/N AX500068). Follow the Replacement and Adjustment procedure on page 6-5 of
the Service Manual.
