Reading and Decoding

Magnetic Encoding Attributes

The magnetic encoding data strings can be given attributes that govern versions of the standard

encode/read-after-write routines and cancellation functions.

The following attributes, inserted anywhere in the applicable data strings, will cause the

following functional deviations from default standards:

Note • The attributes in parenthesis only work for the !M command.

{ (or *) Cancels the read-after-write function. The ticket is encoded and directly

transported forwards for separation (if applicable) and subsequent printing

according to the !F command data without prior read-after-write.

| (or $) Encodes the ticket, performs read-after-write, but does not transport the ticket for

printing. Instead, the ticket is backed into the active position without being cut,

waiting for the command to proceed, for instance, for a decode operation.

} (or @) Expands the read-after-write operation. If this is successful, the ticket is

processed in accordance with standard routines, that is, it is separated and

printed. If the read-after-write operation is unsuccessful in the programmed

number of attempts, the ticket is transported forwards, and the waste bin of the

front load mechanism is activated (only printers with front load & waste bin

option). The ticket is dropped into a waste bin.

|} ($@) Combining the characters | and } results in normal behavior if the encoding was

successful. If an error occurs then the ticket is transported back to the start

position and NAK + ‘E’ is sent.

~ Encodes the ticket, performs read-after-write, and cuts the ticket. The ticket stops

after the cutter (where the after cutter sensor still can see the ticket). Here it waits

for print data and !P command before proceeding to be printed and ejected to the

customer. Apart from print data and !P, only the following commands are

allowed. !L3, !L4, and !L5. !L5 "Eject document into waste bin" will throw

away the ticket from the waiting position into the waste bin without erasing the

data to avoid that the ticket material in the upper track is being pushed out.

— (minus sign) Disables encoding on magnetic retries. If magnetic retries occur it is

almost certain that it is the read-after-write fails due to interference. If encoding

is disabled on the retry, the interference level is drastically reduced and the

possibility of a successful reading increases. This is especially useful for HiCo

tickets.
