NTERFACE CONTROL CODE

The following function codes are used in the high-speed serial interface:

COMMAND CODE

DC1 (17)D (11)H

DC3 (19)D (13)H

Technical Reference Guide – Interface specifications > 30

NOTE

Characters to be printed according to the parity error indication code (40)H will differ depending on the setting of the printer character set. Refer to the printer User’s Guide.

Ready/Busy protocol

Block format Free

Error indication The parity error indication is printed as character

40(H).

Busy state indication The busy signal turns on (becomes Busy) when the

space in the interface buffer has become less than 256 bytes. The busy signal turns off (becomes Ready) after 200 ms or 1 second has passed if 256 bytes have recovered within 200 ms or 1 second. If the recovery time exceeds 200 ms or 1 second, the busy signal turns off (becomes Ready) immediately after the recovery has occurred.

Error indication The parity error indication character is converted

Busy state indication The DC3 will be sent to the transmission side

immediately after the space in the interface buffer has become less than 256 bytes to indicate that receiving is impossible. The transmission of the DC3 stops when data receiving has stopped. If the recovery time for 256 bytes is within 200 ms or 1 second after the DC3 is sent, DC1 will be sent 200 ms or 1 second after the recovery to indicate that receiving is possible. If the recovery time exceeds 200 ms or 1 second, the DC1 is sent immediately after the recovery has occurred.

After the settings outlined in Circuit Test mode setting are completed and power is turned on, the serial interface checks the message buffer memory and interface driver and receiver circuits, then prints all characters. To start and stop this test, press the SEL switch on the front of the printer. Details of this test are explained below.

1. Print the program revision with two numerical characters.

2. Print “LOOP TEST.”

3. Check memory for message buffer.

Print “GOOD” if memory check is OK, and print “BAD” if memory check fails.

4. Transmit characters from code 20H to 7FH by TD signals. At the same time, characters are received from the RD signal and stored in the message buffer.

5. Print the characters that were stored in the message buffer as indicated in Step 4.

6. Repeat from Step 1.

EXADECIMAL DUMP MODE

VERVIEW

Normally a printer prints character patterns that correspond with the input character code. The printer does not print function codes or invalid codes. If the printer does not operate normally, the data sent from the host computer must be checked to determine if the commands are correct.

In this mode the printer converts input data into hexadecimal data and prints all the input data, making it is easy to check all the codes sent from the host computer to the printer.

Technical Reference Guide – Operator interface > 61

PERATION

1. Entering Hexadecimal Dump mode:

While pressing the SEL+LOAD/EJECT switches, turn on the power.

2. Exiting Hexadecimal Dump mode:

Turn the power OFF

3. Print pattern:

The following is an example when data is input from the host computer in the basic format:

> Both parallel and USB interfaces are available.

> Paper auto Skip Over Perforation (SOP) by menu default

value continuous for both. If SOP is enabled, one inch from the bottom of the paper will not be printed.

> Printing starts when more than 16 bytes of data are

received (line full).

ONTINUOUS PAPER AUTO-LOADING

Load continuous paper on the tractor (at a position such that the paper does not cross the paper-end sensor).

In this situation, pressing the LOAD/EJECT switch starts autoloading.

Technical Reference Guide – Operator interface > 62

When the paper does not cross the paper-end sensor within an 8-in feed of the paper, a paper-end state occurs.

The print position of the first data line can be set by menu function or in first character setting mode.

NOTE

TOF is the position that is set when the operation was completed properly.

ONTINUOUS PAPER AUTO-PARKING

With continuous paper loaded in continuous paper mode, pressing the PARK switch starts auto-parking.

When the end of continuous paper is detected by the time the paper is fed 22 in reverse, auto-parking finishes and a paper-end state is established.

If the end of continuous paper is not detected after a 22-in reverse feed, auto-parking terminates. The position that is set when the auto-parking terminated becomes TOF.

Pressing the PARK switch again repeats the auto-parking operation.

The number of reverse movements using the switch is limited to one.

Do not perform reverse feed if the last sheet of continuous paper will come off the tractor.

CUT-

SHEET PAPER SEMI-AUTO-LOADING

By loading paper on the input tray in cut-sheet mode or while waiting for cut-sheet feed, semi-auto-loading starts after the menu-set paper feed wait time (0.5 sec/1.0 sec/2.0 sec) has elapsed.

Once started, cut-sheet paper is fed until the print position of the first data line is reached, the printer is placed in the SELECT state and the operation finishes.

The TOF set at that time is the printing start position of the first data line.

Technical Reference Guide – Command descriptions > 97

> Range:

m selects the available area in RAM. Only available area is m = 0 or 128.

n1 = 00 – 127, Starting character location n2 = n1 – 127, Ending character location

Character width limits are shown as follows:

d0: leading space width

d1: character width

d2: trailing space width

MODE D1 (MAX) D0 + D1 + D2 (MAX)

UTILITY 15 18

LQ 37 42

PROPORTIONAL 37 42

> Out of range:

n1 = n2: One character loaded. n1 > n2: Data up to n2 is dumped and this command is ignored. 80H <= n1, n2: Ignored from ESC to n2.

> Additional details:

To define a character, a grid that is 24 dots high is used, one dot for each wire. The width of the character matrix is dependent upon the character set in use (i.e. LQ, Utility or Proportional).

Dots in the same row may not print in adjacent columns. There must be an empty dot position to the left and to the right of each dot that prints. This is true for Utility, LQ, and Proportional. (See illustrations for character print positioning).

Each vertical column (which has a maximum of 24 dots) is first divided into three groupings of 8 dots. Each group of 8 dots is represented by one byte.
