3.10 Document Draw Adjustment

After replacement of the main PCB or CIS, or if data stored in the E
carry out this procedure by using the TC-027 chart.
Function
This function adjusts how much the document is drawn in, starting at the point when the
document rear sensor is turned on until the leading edge of the document reaches the scan-
ning start position.
Operating Procedure
(1) In the initial maintenance mode, set the TC-027 chart on the document stacker.
The message "DOC. READY" appears on the LCD.
(2) Press the Help key.
The equipment beeps and draws in the TC-027 chart to the scanning start position.
While drawing it in, the equipment counts patterns on the chart to determine the amount
of draw.
Upon completion of normal counting, the equipment shows the message "COPYING
P.01" on the LCD and begins copying the TC-027 chart. The message "REAR SEN-
SOR IS ADJUSTED." and the copied image will be printed out on recording paper as
shown below.
If any error occurs during counting, the message "MACHINE ERROR AB" appears on
the LCD, with no copying of the TC-027 chart onto the recording paper taking place.
However, only the message "REAR SENSOR IS ADJUSTED." will be printed out.
