Bin Sale&TEAR OFF This button selects the paper bin when both optional cut-sheet feeders are installed and you are printing on single sheets. When printing on continuous paper, press this button once to feed paper from the loading position to the tear-off position. Press this button again to feed the paper backward to the loading position. PAUSE (yellow) On when the printer is not ready to print data. On when data is present in the printer's buffer. CONDENSED Press this button to print condensed characters. [. . . ] On when the printer runs out of paper. FONT PAPER OUT (red) BIN 1 (green) On when bin 1 of the optional cut-sheet feeder is selected for paper feeding. Other control-panel features The control panel also gives you access to two special functions: self test: Hold down the LF/FF button (for LQ printing) or the LOAD/EJECT button (for draft printing) while turning on the printer to perform the self test. The self test lets you check that your printer is operating properly and gives you a printout of the current DIP-switch settings. BIN 2 (green) On when bin 2 of the optionai cut-sheet feeder is selected for paper feeding. TEAR OFF (yellow) On when you press the TEAR OFF button to feed the paper to the tearoff position On when a specific font is selected. Fonts(gretm) Buttons PAUSE Press this button to temporarily stop printing. Press this button again to resume printing. Data dump: Hold down both the LF/FF button and LOAD/EJECT button while turning on the printer to enter data dump mode. Data dump mode allows advanced users to find the cause of communication problems between the printer and the computer. Setting the DIP Switches DIP-switch tables The section below shows the settings and functions of each DIP switch. You can see the current DIP-switch settings at any time by running the self test.

If single-sheet paper is already in the loading position, use this button to eject the sheet. lf continuous paper is in the loading or tear-off position, press this button to feed it backward to the standby position. LF/FF (Line feed/Form feed) Tap this button briefly to feed the paper forward one line. Hold this button down to eject a single sheet of paper or advance continuous paper to the top of the next page. You can also use this button to load a single sheet of paper from the cut-sheet feeder or to feed continuous paper from the standby position to the loading position. 1 Unldwctlonal j Off / None I On Bidvechonai ~ On 18 K b y l e s 1 on 24-Pin Printers 8/20/91 LQ-850+/1070-3 LQ-850+/1070 Table 2 DlP switch 2 gi 2-2 [ 2-3 / I 2-4 Dewtptlotl Page length (for contmuo~s ' paper1 ~Tearoff Auto line feed ON OFF I See Table 5 below 1 on on Off off / Country 0 USA 1 Frame 2 Germany 3 UnltedKingdom 4 Denmark I 5 Sweden 6 Italy 7 Spam I I f # t International character sets ASCII code (hex) DIP switch 23 24 40 50 SC 5D SE 60 78 7C 7D 7E l-l 1-2 1-3 14 S $ a h l [ q \ 3 I A a ' ' 6 1 I D ) ib " OnOnOnOn; OnOnOffOn Table 3 ~ntemational character sets cc4mtry I USA !Connector pin assignments and a description of their respective interface signals are shown in the following table.

"Return" denotes the twisted-pair return, to be connected at signal ground level. [. . . ] For the interface wiring, be sure to use a twisted-pair cable for each signal and to complete the connection on the return side. Both the rise and fall times of each signal must be less than 0. 2 microseconds. Data transfer must be carried out by observing the ACKNLG or BUSY signal. (Data transfer to this printer can be carried out only after receipt of the ACKNLG signal or when the level of the BUSY signal is LOW. ) l l l 24-Pin Printers LQ-850+/1070-5 LQ-850+/1070 Interface timing The figure below shows the timing for the parallel interface: Paper: I 1 Width I I C80637' C8C638 C80639' ; C80640' I ) Length Thickness Weight \ 0. 5 + (Min. ) Slngls sheets 182to216mm (7. 17 to 8. 50 Inches. ) I182to216mm 1 (7. 17 to 8. 50 Inches) ; 182to420mm I (7. 17 to 16. 54 inches) / 182 to420 mm ( (7. 1710 16. 54 Inches) ;210to305mm I (8. 27 to 12. 00 Inches) 0. 07 to 0. 10 mm ~(0. 0028 to 0. 0039 Inches) 64 to 82 g/m' (17 to 22 Ibs) I Envslopes N/A 1 / 165 to 241 mm (6. 50 to 9. 49 inches) N/A i 185to241 mm 1 (6. 50 to 9. 49 Inches) j E$ :z. gnches) 0. 16 to 0. 52 mm (O.
