placed with the 9-edge down and column 1
away from you.
4. Replace the card follower. The device is
capable of reading a variety of cards but
only one hole reading format at a time;
mixing of 80-and 51-column cards is not
recommended. In devices utilizing the mark
sense option, data may be punched or
marked or may consist of both punches
and marks on the same card in one selected
hole reading format.
5. Operate the device according to the para
graph entitled, Standard Power-Up Pro
cedures.
Card Unloading
When the input hopper runs out of cards, the
card transport motor will automatically come to a
stop. Remove the cards from the output hopper
and if no more cards are to be run, power-down
the device according to the paragraph entitled,
Standard Power-Down Procedures.
Card Loading And Unloading On-The-Fly
Loading and unloading on-the-fly is permiss
able and should offer no problems provided that
the following procedure is observed.
I.
Lift the card follower when loading on
the-fly, as the level of the cards in the input
hopper must not be allowed to get below
100 cards to ensure reliable picking. A
convenient gauge for this is do not let the
card stack in the input hopper get lower
than three quarters of an inch in thickness.
2. Two hands must be used to unload the
output hopper. The procedure that works
best is to hold up the cards coming into the
output hopper with the index finger of the
left hand while removing the stack of cards
from beneath this index finger with the
right hand. When removing cards from the
output hopper in this manner, it is rec
ommended that the stack of cards taken
out at a time not be thicker than about two
inches for ease of removal.
Card Mispicks
If
the card reader has difficulty picking a card
when reading a deck of cards, it will attempt to
repick up to two additional times. If unsuccessful,
the card reader will stop picking, the card
transport motor will stop, and the RESET indica
tor on the card reader panel will light. The
CARD READER DEVICES
bottom card of the stack in the input hopper will
be the defective card. If not too damaged, the
card edge may be flattened out enough to run by
drawing the damaged edge of the card between
the thumb and forefinger of one hand. After
replacing the damaged card on the bottom of the
remainder of the deck, and jogging the cards
again, replace the deck in the input hopper with
the card follower on top. Pressing the RESET
button will restart the motor, reset the logic, and
allow the device to complete the reading of the
deck.
OPERATOR MAINTENANCE
Operator maintenance is the preventive main
tenance required by an operator in maintaining
proper operation of the card reader. Preventive
maintenance includes the checks, cleaning, oper
ating habits, etc., done periodically on a sched
uled routine basis, even though card reader
operation may be satisfactory and not in need of
attention. The purpose of preventive maintenance
is to keep the card reader and its components in
the best of operating conditions at all times,
reducing the chance of "down-time" and the need
for further maintenance.
Care And Handling Of Cards
The following common sense rules are the
prerequisites for proper card handling and stor
age.
o Prior to input hopper loading, cards should
be checked visually for appearance and
condition. The proper handling of cards
during loading and unloading is important;
see paragraphs entitled, Card Loading and
Card Unloading.
o To avoid a card jam or possible mutilation
of a card, observe the procedures describing
Card Loading and Unloading On-The-Fly,
and Card Mispicks.
o Avoid smears and smudges when marking
mark sense cards.
o Don't smoke in the computer room or near
the device, but if you must, be extremely
careful. Smoke and ashes are dirt; hot ashes
are destructive to cards. Food and drink
should be prohibited.
o The proper storage of cards when not in
use will increase the life expectancy of the
cards and eliminate the possibility of card
jams.
