1.1 FEATURES
The FX-850 and FX-1 050 are serial dot matrix 9-pin terminal printers that print at a maximum of 264 CPS. Either model FX-850 with 80 columns or FX-1 050 with 136 columns can be selected according to your requirements. The main features are as follows: 264 CPS (Draft and Elite) q Max. printing speed: 220 CPS (Draft and Pica) q Advanced paper handling functions: Auto tear-off Auto loading Auto back-out Micro adjustment q SelecType function (Any print mode can be selected directly from the front panel). Once a mode is selected, it is stored in the non-volatile memory, and is selected when the printer power is turned on. q Two NLQ fonts (Roman and Saris-serif) are standard. q Printer driver EPSON ESC/P-83 is standard. (This driver is compatible with the high class models such as FX-800, -1000, -86e, and -286e.) q Double-height function q Pitch control is possible in the NLQ mode. (Pica, elite, proportional modes) q Since the IBM emulation mode is standard, these printers are IBM-compatible. The IBM characters are also standard. q 8K-byte input data buffer (Buffering can be disabled.) q Push tractor unit q Printing is possible on envelopes and labels in addition to fan-fold paper, cut sheets, and roll paper. q User-defined characters are supported in both the Draft and NLQ (Saris-serif) modes. Once a character is registered, it is stored in the non-volatile memory and need not be re-registered. The user-defined character set can only be selected (as a default character set) using the DIP switches. q Compatible with EPSON optional interface board series #81 XX.

NOTES: 1. "DIR" refers to the direction of signal flow as viewed from the printer. 2. "Return" denotes "TWISTED-PAIR RETURN" and is to be connected at signal ground level. As to the wiring for the interface, be sure to use a twisted-pair cable for each signal and never fail to complete connection on the Return side. To prevent noise effectively, these cables should be shielded an connected to the chassis of the host computer and the printer, respectively. 3. All interface conditions are based on TTL level. Both the rise and fall times of each signal must be less than 0.2Ks. 4. Data transfer must not be carried out by ignoring the ACKNLG or BUSY signal. (Data transfer to this printer can be carried out only after confirming the ACKNLG signal or when the level of the BUSY signal is "LOW".)

NOTES: 1. In the Table 1-18, it is assumed that no ERROR status exists other than that attributable to OFF-LINE mode. 2. Once the printer is deselected by the DC3 code, the printer will not revert the selected state unless the DC 1 code is input again. (In the deselected state, the printer ignores input data until the DC 1 code is received.) 3. The DC 1 and DC3 codes are enabled only when the SLCT-IN signal (Input Connector No.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, DC l/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 6 when printer initialized, the printer starts from the selected (DC 1 ) state. f-:

REV.-A 1.4 DIP SWITCHES AND JUMPER SETTINGS This section describes the DIP switch selections and jumper setting for the FX-850/l 050 printer. 1.4.1 DIP Switch Settings The DIP switches are located at the right side of the printer. When the printer hardware is initialized, the following functions are set to the default values shown in the table below. Table 1-19. DIP Switch 1 Settings

International character set
See Table 1-20.
NOTE: When DIP SW1-4 is on (IBM mode), the function of DIP SW1-3 changes to auto CR ON/OFF. Default character set When DIP switch 1-1 is ON, the user-defined character set will be selected as default. User-defined characters are maintained in printer memory even when the power is turned off, so the user-defined character set can be easily selected simply by turning off the power, setting this switch to ON, and then turning the power on again. Shape of zero When DIP switch 1-2 is ON, prints a stashed zero (0); when OFF, prints open zeros (0). Useful for clearly distinguishing between uppercase O and zero when printing program lists, etc. Protocol mode When DIP switch 1-4 is ON, printer operates in the IBM emulation mode; when off, printer operates in the Epson ESC/P mode. Functions of DIP switches 1-6, 1-7, and 1-8 are different when using the printer in the IBM emulation mode. Short Tear-off When print operation has finished, the short tear-off feature automatically feeds the perforation of the continuous paper to the tear-off edge of the sheet guide cover so that the user can tear off the last sheet. When the user resume printing, the paper is fed backward to the loading position.

1.6 HEXADECIMAL DUMP FUNCTION
The hexadecimal dump function causes the printer to print the received data in hexadecimal. The printer prints 16 values in hexadecimal, followed by the corresponding ASCII characters, on one line. If there is no corresponding printable character for a value (i.e. a control code), a period (.) is printed. Any remaining data (less than 16 values) can be printed by operating the ON LINE switch. No panel settings can be made in the hexadecimal dump mode. This function makes it easy for technician to identify the source of communications problems between the printer and computer. Table 1-24 lists the self test operating instructions and Figure 1-9 shows the hexadecimal dump printing. Table 1-24. Hexadecimal Dump Operation

1.7 PRINTER INITIALIZATION
There are two initialization methods: hardware initialization and software initialization. 1.7.1 Hardware Initialization This type of initialization occurs when printer power is turned on or when the printer receives the INIT signal from the host computer via the 8-bit parallel interface. When printer is initialized in this way, it performs the following actions: q Initializes printer mechanism. q Sets the on-line mode. q Sets the page length to 11 or 12 inches according to the DIP switch. q Clears the input data buffer and print buffer. q Read DIP switch and jumper settings. q Sets the print mode according to the DIP switch and the non-volatile memory set by control panel. q Sets printer selections to their default values 1.7.2 Software Initialization This type of initialization occurs when the printer receives command (ESC @) via software. When the printer is initialized in this way, it performs the following actions: q Clears the print buffer. q Sets printer selections to their default values. NOTE: The printer's default values are as follows: Page Position Left and Right Margin Line Spacing Vertical Tab Position Horizontal Tab Position VFU Channel Downloaded Characters Justification Character Per Inch Preset paper position becomes top of form position Released 1/6 inches Cleared Every 8 characters (relative) Channel O Deselected: Software initialize Cleared: 10 ESC Z = ESC X 3 Printing Effects

1.9 PAPER HANDLING FUNCTIONS
The push tractor unit can be easily mounted or removed using the paper release lever. Either continuous paper or cut sheets can be easily selected by operating the LOAD/EJECT switch and paper release lever. Various paper handling functions are described below. 1.9.1 Autoloading and Backout Function Loading and ejecting a cut sheet: When no sheet is loaded, push the paper release lever backward, load the sheet along the sheet guide, and press the LOAD/EJECT switch so that the sheet is automatically fed up to the TOF position. When the LOAD/EJECT switch is pressed with a sheet loaded, the sheet will be ejected. Loading and ejecting continuous paper (auto back-out): Pull the paper release lever forward, load continuous paper onto the push tractor unit, and press the LOAD/EJECT switch so that the paper is automatically fed up to the TOF position. When the LOAD/EJECT switch is pressed with the paper loaded, the paper is fed in the reverse direction (ejected) up to the tractor waiting position (auto back-out). If the paper cannot be fed in the reverse direction at 1/6 inch line spacing, the paper ejection process will be terminated. 1.9.2 Short Tear-Off Function For continuous paper (when the paper release lever is moved to the tractor feeder side), the paper will be automatically fed to the perforations (tear-off position) when printing is completed, no data is being received from the host computer, and the print buffer is empty. At this time, the micro-adjustment TOF set function becomes valid so that the tear-off position can be adjusted accurately using the LF and FF switches. The adjusted tear-off position is stored in the memory and remains valid even after the printer power is turned off, so that the paper will be automatically fed to that position when the tear-off function is executed later. After the paper is cut off, the paper is automatically returned to the previous position by sending new print data or setting the printer OFF LINE. 1.9.3 Micro-Adjustment Top-of-Form Set Function After paper loading is completed, set the printer ON LINE by pressing the ON LINE switch. In this state, the paper loading position can be finely adjusted by operating the LF and FF switches. When the printer is in the micro adjustment mode, the ON LINE LED on the panel blinks. The paper loading position can be adjusted individually for the friction feed, tractor feed, and cut sheet feeder modes, and the adjusted values are stored in the memory. The value for the tractor feed remains valid even after the printer power is turned off. NOTE: If paper is already loaded when the printer power is turned on, the position of the paper will be recognized as the TOF position.

1.10 PAPER END DETECTION
The paper end is detected by the PE sensor. When the paper end is detected, the printer indicates it
by lighting the lamp on the control panel and ringing the buzzer. The printer sets the parallel interface signals as shown below, and enters the OFF LINE mode.
q BUSY signal: HIGH q PE signal:
HIGH . ERROR signal: LOW After the paper end is detected, load a new sheet and press the ON LINE switch so that the printer enters
the ON LINE mode. Figure 1-10 shows the paper end detection position.
