1. Connect the printer cable at the back of the IW II.
2. Remove the AppleTalk Option card
3. Check that the top panel is installed correctly.
4. Check that paper is installed.
5. Turn off the printer, write down the customer's Super Serial Card and printer DIP switch configurations. Set the DIP switches as shown below:

(Note: Op = open, Cl = closed, up = On, dn = Off)

IW II _____________SW1____________ _________SW2__________
Op Op Op Op Op Cl Op Op Cl Cl Op Op Cl Op
1 2 3 4 5 6 7 8 1 2 3 4 5 6

S/S Card ___________SW1__________ __________SW2_________ MODEM/TERM
Off Off Off On Off On On On Off Off On On Off Off jumper
1 2 3 4 5 6 7 1 2 3 4 5 6 7 to term

On the ImageWriter II, DIP switch 4, on SW2 is OPEN if Localtalk Option card is not installed, and CLOSED if the LocalTalk Option card is installed.

6. Remove all peripheral cards from the IIe. Install the Super Serial
card in slot 1. Connect the IW II to the S/S card using a printer cable
Turn on the IW II (make sure cover is installed). Turn on the IIe and
press the RESET key while you press the CONTROL key (DO NOT BOOT A
DISK). The cursor should blink.

Enter the BASIC program exactly as shown below.

10 PR#1
20 FOR A = 1 TO 100
30 FOR I = 32 TO 126
60 PR#0
70 END

Enter RUN and press the <RETURN> key. The printer should print out about
100 character sets something like the one shown below:


* If you get a syntax error on the computer, you may have mis-typed a
line. To correct the syntax error perform the following:

1) Type LIST and press <RETURN>. The program should appear on the screen.
2) Examine the program for accuracy. Spaces, colons, etc. are important.
3) To correct a line, simply retype the line and press <RETURN>.
4) LIST again to make sure the correction is OK.

* If the IW II prints characters when the program runs, the printer is functional.

* If it doesn't and there is no syntax error on the computer, check
for the problems below:

PROB: The printer does not print a set of characters.
FIX: Recheck for the problem after each of the following steps. If
no problem is found, go to step 4.
(1) Check that the computer is properly powered on and initialized.
(2) Check that the SEL light is on. If it's not, press SEL and try
to print from the computer again using the program above. If
it prints while the SEL light is off, replace the switch panel.
(3) Make sure that the interface cable between the printer and the
computer is connected and secured at both ends.
(4) Replace Main CPU PCB.
(5) Replace printer internal connector cable.

PROB: The printer prints a set of characters but print quality is
FIX: Do a word search for HTS and IMAGEWRITER II and PRINT QUALITY
to obtain the print quality FIX.

7. Reset the DIP switches to the customer's original configuration. Then refer to the User's Manual and the Appendix in the ImageWriter II section of the Tech Procedures to see if the customer's DIP switch configuration caused the problem.
