NOTES: 1. In Table 1-10, it is assumed that no ERROR status exists other than that attributable to
OFF-LINE mode.
2.
Once the printer has been put in the deselected state by the DC3 code, the printer will not revert
to the selected state unless the DC1 code is input again. (In the deselected state, the printer
ignores input data until the DC1 code is received.)
3. The DC1 and DC3 codes are enabled only when the SLCT-IN signal (Input Connector Number
36 for the parallel interface unit) is HIGH and printer power is initialized.
4. If the SLCT-IN signal is LOW when the printer is initialized, DC1 /DC3 printer select/deselect
control is invalidated, and these control codes are ignored.
5.
If the SLCT-IN signal is HIGH, and is not set to LOW by jumper 10 when the printer is initialized,
the printer starts from the selected (DC1) state.

GENERAL DESCRIPTION

1.6 SHEET LOADING AND SHEET EJECTION
The release lever enables disengaging of the push tractor unit drive mechanism. The printer therefore provides some improved paper-handling functions through combination of the release lever and LOAD/EJECT
control panel switch.
Cut-Sheet Loading and Ejection
To load a sheet of paper, position the paper-release lever back, place the sheet along the paper guide, and
press the LOAD/EJECT switch. This loads the paper to the top-of-form position. Pressing the LOAD/EJECT
switch after the paper has been loaded will cause the paper to be ejected.
Continuous-Paper Loading and Ejection (Back-Out)
To load fanfold paper, move the paper-release lever forward, and insert the paper into the push tractor. Pressing
the LOAD/EJECT switch will then cause paper to be automatically loaded to the top-of-form position. Pressing the LOAD/EJECT switch after the fanfold paper has been loaded causes the printer to eject the paper
backward from the push tractor. To back out several pages, press the LOAD/EJECT switch several times
(reverse feed is performed on a page-by-page basis).
The MULTI-PART LED will flash only when the paper is loaded and the ON LINE switch pressed. This in-
dicates that the printer has entered “top-of-form adjust” mode, and that the user may adjust the top-of-form
position, as well as the loading positions for subsequent forms. Adjustment is made using the FORM FEED
button, which will increment the paper forward, and the LINE FEED switch, which will increment the paper
in reverse. (The minimum feed amount is 1/,80 inch.) When the cut-sheet feeder is used, the adjusted position
for the top of form will be lost after the printer is reinitialized, and the top of form will be reset to the default
value. When continuous paper is used, however, printer memory maintains the adjusted top-of-form position
even after printer initialization.
1.7 TEAR-OFF FUNCTION
If the tear-off function is enabled by making the appropriate DIP switch setting, it operates when the release
lever is set to the tractor position. In this case, if the input data buffer is empty and the printer is on line,
the paper is automatically fed to the tear-off position, and the MULTI-PART LED flashes to indicate that the
FORM FEED and LINE FEED switches are now available to perform micro-adjustment. The user may then
adjust the paper to the desired tear-off position. This position becomes the new tear-off position default, and
will remain valid even if the printer is reset and reinitialized, and regardless of whether the main power has
been interrupted. When new data is input to the printer, the paper is automatically returned to its original
position, and printing then starts. Paper that was advanced to the tear-off position will also be returned to
its original position if the ON LINE switch is pressed (switching the printer from on line to off line).

1.8 OPERATING INSTRUCTIONS
This section describes the self-test and hexadecimal dump functions, error states, printer initialization, and
buzzer operation.
1.8.1 SELF-TEST
To begin self-test printing in draft mode, turn the printer on while depressing the LINE-FEED button. To begin
printing in letter-quality (LQ) mode, turn the printer on while depressing FORM FEED.
Self-test printing can be stopped and restarted by pressing ON LINE (this will not affect the ON-LINE in-
dicator). To conclude the self-test, press the ON-LINE switch to stop the printing; then turn off the printer.
The first printed line of the self-test indicates the firmware revision number. Following this line, the current
DIP switch settings are printed.

1.8.2 HEXADECIMAL DUMP FUNCTION
HEX dump mode is activated if the printer is switched on while both the LINE-FEED and FORM-FEED buttons are depressed. When this mode is in effect, the hexadecimal representation of the input data is printed
beside the corresponding printable ASCII characters. Periods (.) are printed beside control code input data.
This function is useful for checking the data the printer is receiving from the host.

GENERAL DESCRIPTION
1.8.3 BIT-IMAGE PRINTING
This printer offers the following four standard print densities (“dpi” indicates “dots per inch”):
120 dpi (including half dots): Triple speed
180 dpi (including half dots): Double speed
240 dpi (including half dots): 1.5 speed
360 dpi (including half dots): Normal speed
The firmware implements the print densities as shown in Table 1-16.
