BULLETIN NUMBER:
APPLICABLE MODEL:
GESTETNER – 5329L
RICOH – VT2250
SAVIN – 3250DNP
SUBJECT: MASTER END DETECTION FAILURE
SYMPTOM:
The machine continues to rotate the Master Roll even after the actual end condition is reached, which then
strips the roll paper from the roll. The very edge of the roll paper stripped from the roll contains adhesive
causing a jam when it sticks to the Master Feed Rollers.
CAUSE:
The Master End Sensor does not detect the black end stripe on the roll due to performance variations.
SOLUTION:
Change the sensor, or adjust the sensor's position as shown below in Field Countermeasure.
An output check for the Master End Sensor has been added from July 2001 production.
FIELD COUNTERMEASURE:
Sensor position adjustment procedure:
1. Unplug the power cord and slide the Scanner Unit to the left as seen from the operation panel side.
2. Lift the release lever and remove the Master Roll.
3. Raise the sensor position by installing a 0.2mm-thick spacer as shown above (P/N 08072071). If this
spacer has no effect, install one more 0.2mm spacer or remove the first one and use a 0.4 mm spacer
(P/N 07010030Z).
