Xerox WORKCENTRE 7120 Manual de referencia
When the reader is in the "automatic" mode, the START in-
dicator is illuminated and the STOP indicator is extinguished.
STOP
Operation of this momentary switch-indicator changes the
card reader from the "automatic" to the "manual" mode.
The STOP indicator is illuminated, and the START indicator
is extinguished, only whi Ie the unit is in the "manual" mode,
with the current, in-process card read operation being com-
pleted. The reader enters the "manua I" mode if any of the
following conditions occurs:
1.
The STOP switch is operated.
2.
The input hopper is empty.
3.
An output stacker is full.
4.
The RESET switch is operated.
5.
The unit becomes not operational.
FEED/READ
If either section of this split field indicator is illuminated,
the unit is in the "not operational
II
condition.
The FEED
section is illuminated when a transport feed error is de-
tected. Feed errors are defined as follows:
1.
Failure to pick and del iver a card to the read station.
2.
Fai lure of card to exit throat area.
3.
Failure of card to exit read station.
4.
Failure of card to reach stacker area.
5.
Card jam in stacker area.
6.
Erroneous picking of card (picked without command).
Note:
Reader motor power is off whenever the FEED
indicator is illuminated.
After the fault condition has been corrected, operation of
the RESET control clears the FEED indi cator.
The READ section is illuminated when a photoelectric sys-
tem error is detected. A "Iight-dark" check on the read
station is performed at the start of each card cycle.
Fai l-
ure of this check causes the READ indicator to light.
Op-
eration of the RESET control clears the READ indicator.
For Model 7140-01,
if
the READ section is illuminated or
both the FEED and READ sections are illuminated, the last
card fed should be reloaded into the input hopper before
resuming operation.
For Model 7140-02, if the READ sec-
tion is illuminated or both the FEED and READ sections are
illuminated, the last card fed should be reloaded into the
input hopper before resumi ng operation.
If only the FEED
section is illuminated, do not reload the last card fed.
RESET
Operation of this momentary switch clears the FEED/READ
error indicators and places the unit in the "manual" mode
at the completion of the current card read operation.
Operation of this switch whi Ie a reader photo-element is
covered will put the reader in the "manual" mode but will
not clear read and feed errors. The reset signal is also sup-
plied to the controller for input/output system requirements.
HOPPER/ST ACKER
The HOPPER section of this split field indicator is illumi-
nated when the input hopper is empty. The STACKER section
is illuminated if an output stacker is full. The card reader
will be in the "manual" mode if either section of the indi-
cator is illuminated.

CARD FILE LOADING PROCEDURE (MODEL 7120)
1.
Ensure power is applied by visually checking the
OPER'L/POWER switch on the operator control panel.
Illumination of the POWER switch and audible mechani-
cal operation indicate ac and dc power are appl ied
and the read station and transport mechanism are
operative.
2.
Remove the card weight (and cards, if present) from
the input hopper (see Figure 11).
Press the RESET
switch to feed the card (if present) from the card read
platform into alternate stacker 2 (see Figure 12).
