BASIC OPERATION 6 March 1992
4. BASIC OPERATION
4.1 JOB SHEET READING
[A]
[C][B]
When a job sheet is inserted, the sheet detection sensor [A] detects the
leading edge of the job sheet. The job sheet is then fed in by the upper and
lower transport rollers [B, C].
4
Page 6
6 March 1992 BASIC OPERATION
[A]
[C]
[B]
[D]
[F]
[E]
[G]
The mark detection sensor [A] detects the reference line [D] and reads the
job sheet. The mark detection sensor is composed of 4 photosensors. The
sensor on the right [B] detects the reference line and reference marks [E],
and the other sensors [C] read the job sheet data.
The menu reader CPU monitors signals from the mark detection sensor and
measures the time between each reference mark. There are 25 reference
marks along the sheet edge. After the 25th reference mark is read, the job
sheet is fed out by the upper and lower transport rollers [F, G].
The operation panel status changes after the job sheet is read, and the job
sheet information is sent to the copier CPU.

4.3 PROCESSING ERRORS
Reference Line
If the reference line does not reach the mark detection sensor within 2.6
seconds after the job sheet is fed in, the job sheet is fed out. (Feeding out
takes 1.6 seconds.) The red light blinks for 6 seconds; then, the job sheet
can be reinserted.
Reference Mark
If the mark detection sensor detects the reference line and then fails to detect
a reference mark within 0.2 seconds, or if it fails to detect a reference mark
within 0.1 seconds, the job sheet is fed out and the red light blinks for 6
seconds; then, the job sheet can be reinserted.
NOTE: Occasionally, the job sheet feeds out to the rear side of the menu
reader after a failure to detect the reference mark number.
Marking
When two or more selections are made for the same item, the menu reader
cannot process the job sheet and the red light blinks (indicating an error).
NOTE: 1. When an item is not marked on the job sheet, the menu reader
automatically reads as follows:
-- Item -- -- Indicator - Copy Quantity 1
Reproduction Ration 100%
2. The job sheet may jam inside the menu reader if it is smaller
than the specified size.
CAUTION: Sensors were set at the factory and cannot be adjusted in
the field.
