FF code

(X'OC')

When receiving the FF code, the printer advances the form to the

channel-l position

(TOF)

specified by data in the FCB or format

control tape

(FCT).

When channel 1 is not specified, the printer

treats the first line on a page as the TOF and advances the form to

that position.

CR code

(X'OD')

The CR code indicates the end of a line. When it receives the CR

code,

the printer prints characters corresponding to the received

character codes starting from column 1. Either one-line forms feed

mode (this is the same as the mode selected by the LF code) or

forms-feed inhibited mode can be selected for after printing.

FCB command control code

(X'lF')

When

,it

recei.ves

two bytes of the FCB command control code and the

subsequent FCB command,

the printer terminates the data transfer

cycle and prints the contents of the PDB, then advances the form as

specified.

For details on the FCB commands, see Section 5.5.

(2) ESC code

(X'IB')

The ESC code is used to switch the line spacing (6 LPI or 8 LPI) from the

host.

The host issues the ESC code before loading the FCB data. The ESC

code is required only if the line spacing must be switched.

The line spacing is specified in one byte after the ESC code, as follows:

ESC

(X'lB')

+ 6

(X136')

Set to 6 LPI.

ESC

(X'lB')

+ 8

(X138')

Set to 8 LPI.

ESC

(X'lB')

+ 0

(X130')

Reset to the line spacing specified on the

operator panel.

The ESC code function can be disabled by setting on the operator panel.

(3) Start code

(X'lD')

and stop code

(X'lE')

The start and stop codes are used to load the forms feed format in the

FCB.

Within 300

after it receives the start

c&s,

the printer sets the

Busy signal to 0,

enabling FCB data to be received. For details on FCB

data reception, see Section 5.4.1.
