          SCANNER V1.3



   Ckaner kopiruet izobrazhenie a lista nA
ekran, prosmatrivaya ego posledovatelno,
tochka za tochkoy with pomoschyu fotodatchika. For
move fotodatchika ispolzuetsya movement golovki printera at 
pechati. 



            OPICANIE PROGRAMMY



   Posle starta programmy By popadaete in
menu, kotopom mozhete ustanovit one Shout out

course defines the rasstoyanie between kraynimi provisions of

than shirina karetki printera.Parametr "speed" is used to 
determine pravilnogo vnutrennix peremennyx, svyazannyx with

ravnym speed pechati Bashego printera taken from pasporta 
printera (N znakov per second). Bas should not be surprising 
change znacheny parametrov after exit the menu, as programma 
vybiraet blizhayshy of vozmozhnyx skanirovaniya regimes.

       Procedure nastroyki programmy



1. In the programme ustanovlen drayver compatible LPRINT III 
with paralelnym obmena protocol and system komand tipa 
CENTRONIC. Try zapustit programu and achieve change zaderzhki 
rhythmic movement pechatayuschey head. At the time peredachi 
informatsii nA printer nA curb voznikayut black and white 
stripes. White border pokazyvaet the printer in time danny

zanyat. Women should be unto you get to move sleva napravo 
proisxodilo in black curb. Ha first etape unto you do not need 
fotodatchik. Printer at the same time draws two vertikalnye 
line. If the printer is moving erratically, and his movement in 
proisxodit moments, kogda white border, then programma

y vas rabotat will not. More precisely, neobxodima
peredelka code chasti. Poka udalos reveal only large screen 
razlichnyx tipa printera - "Robotron" - pechataet informatsiyu 
srazu, after receiving komandy "BK", a "CPRINT",

"MC 6912", nachinayut pechat previous line only after receiving 
upravlyayuschix komand the next line. 

   Because sinxronizatsiya otobrazheniya nA ekrane carried out 
on time, podprogrammy for skanirovaniya, rabotayuschie with 
printerami raznyx types razlichayutsya bit. 

   If your printer is not Vash dvigaetsya, then sledovatelno, 
unto you do not podxodit used drayver. Because the vas is 
printer, then the vas must be drayver pechati. Zapishite him 
adresa 41604 and try snova. Trebovaniya to drayveru simple: he 
must bayt "13" - "BK" supplement Code "10" - "LF", a ostalnye 
codes peredavat nA printer without obrabobotki. Address zapuska 
should sovpadat with nachalom, and his dlina dolzhna be less 
than 256 bytes. 

2. Having made fotodatchik rabotu-check it using the "test 
fotodatchika," he should clearly reagirovat nA color bumagi.


3. Ustanoviv fotodatchik nA printer and changing parametr 
"shift" until you get the appearance of nA ekrane Although some 
would kakogo izobrazheniya. If you ustanovili color: bumagi - 7 
(white) a color ink - 0 (black), then izobrazhenie

should be "positive." Lack izobrazheniya pokazyvaet that, 
either at the time skanirovaniya datchik not moving and Women 
should be change zaderzhku or datchik not feel change Colors 
vashego risunka and Women should repeat item 2 (test 
fotodatchika). 

4. If you have received neproportsionalny figure, but did not 
change parametry nastroyki except sdviga, the Women should be 
zapomnit znachenie parametra "SHIFT" and go to the menu 
nastroyki, change parametr "speed printera and ustanovit mode 
STANDARD SETUP ".


   Increasing the speed printera vyzyvaet
szhatie izobrazheniya on gorizontali. In the skanirovaniya 
Women should snova ustanovit naydennoe vami znachenie sdviga, 
and after nastroyki vsex regimes zapisat nA

disc obtained znacheniya. When you
zapuske programmy nastroyka would merely
to the choice of one of the modes.

skanerom, you can obratitsya on adresam, ukazannym instructions 
for making fotodatchika you found in the Appendix.

           Additions to HELP'u

           ===================



              INTRODUCTION



   The amendment applies to the last
version of the "SCANNER v1.3", designed for computer 
ZX-SPECTRUM, equipped with a jet or dot matrix printers, but 
all the previously developed materials for scanning head 
version 1 remain valid for this version. 



           Scanning head



   This version includes a trio of graduation
the contrast of the image, slightly modified design of the 
scanning                    agile (Fig. 1), processing

                   oped a code of

                   Program Support

                   scanner, are eliminated on
                   naruzhennye errors and

                   introduced some improvement
                   solution in the design

                   Readhead.

                      For example, before

                   photosensor (FT) before
                   assumed set of
                   sharp medical needles
diameter of 0.3 - 0.5 mm in length, approximately ,3-5mm. It is 
necessary to choose experimentally a particular photosensor 
according to the sensitivity of its reception. 

   It is also proposed to equip the scanning head, or rather, 
the backlight head - a protective shield (EC), reinforcing 
luminous flux scanned image. 

   Optimum tilt angle needle photosensor (FT) - 10 - 20 degrees.



               WIRING



   Scanner Version 1.3 readjusted circuit, according to

                   Figure 2.


                    The main difference between this

                   scheme is that

                   output stage gain
                   equipped with a filter of

                   RD, ie, signal is divided

                   3 levels with

                   Resistance: R4, R5, R6

                   and diodes: D1, D2.



   Outputs 1, 2, 3-band filter, respectively, with terminals: 
down - right - left (4 - 1 - 2) port 31 Kempston-joystick.


   Some parts for the electrical ratings:

R1 - 20-120 K R2 - 40-100 K R3 - 0.8-1 K
R4 - 2 TO R5 - 20 K R6 - 60 K
D1, D2 - any diodes with direct Pair. 1.5-2 K


IC LE 1 Series 555 or similar.

NOTE: If you are making head
you could not save the contact plate on the printhead, then in 
its place Glue necessarily PCB thickness of 0.5

mm in order to save the contact printer.
