A NOTE ABOUT THE RED ERROR LIGHT:
If the ERROR LIGHT stays lit: Check and make sure that the printer is
not out of paper. The paper-out switch or main CPU PCB might be
defective if the printer has paper inserted properly.
The ERROR LIGHT blinks at regular intervals: Check to make sure that
the cover is securely fastened and that the magnet is still in place
(located under the front right of the cover). Sometimes the magnet
becomes loosened and falls out. Also, check to make sure that a paper
jam has not occured.
The ERROR light blinks irregularly: Check DIP switch 4 on Switch 2. DIP
switch 4 should be set to the "closed" position if the AppleTalk Card or
Memory Card is installed. Otherwise DIP switch 4 should be set to
BEFORE YOU START:
1. If replacement or adjustment procedures are needed, refer to the Tech
2. If location for IW II controls is needed, refer to the User's Manual.
3. Install the color ribbon on the printer.
CHECK 1: PRE-PRINT
1.1 Disconnect the printer cable at the back of the IW II.
1.2 Remove the AppleTalk Option card
1.3 Check that the top panel is installed correctly.
1.4 Check that paper is installed.
1.5 Turn the platen knob.
PROB: The platen binds or doesn't turn consistently.
FIX: Take off the top cover, pull off the platen knob and
check for obstructions in the gears
1.6 Move the carriage back and forth along its full length of travel.
PROB: The carriage binds or doesn't move consistently.
FIX: Check if carrier belt is properly installed.
Check for obstructions. "Very" lightly lubricate
the carrier shaft with tellus lubrication oil.
CHECK 2: POWER ON INITIALIZATION
As you turn on the printer, check for NORMAL PRINTER ACTIONS below.
NORMAL PRINTER ACTION IF NOT THEN
The power lamp lights. Search on HTS and ImageWriter II
and Power/Carrier problems
The carrier should move Search on HTS and ImageWriter II
slowly to its leftmost position and Power/Carrier Problems
then rapidly to its center position
The platen should rotate one line Search on HTS and ImageWriter II
backward and one forward and Line Feed Problems
The ribbon frame assembly should Search on HTS and ImageWriter II
tilt down about two lines and and Color Select Problems
then up to become level again.
The SEL lamp lights. Search on HTS and ImageWriter II

CHECK 3: SELF TEST
To initiate Self Test: turn the printer off and press Form Feed while
you turn it back on. The printer should print:
DIP switch settings
RAM XX AT On or OFF
and then begin printing lines of CHARACTER SETS in alternating colors.
If the Self Test occurs as described above and the print quality is
good, go to CHECK 4.
If the printer doesn't print character sets or the print quality is
poor, search on "HTS and Imagewriter II and Self Test". The document you
will obtain contains fixes for IW II Self Test problems.
CHECK 4: HOST PRINT
4.1 Turn off the printer, write down the customer's Super Serial Card
and printer DIP switch configurations. Set the DIP switches as shown
(Note: Op = open, Cl = closed, up = On, dn = Off)
__________IW II-SW1__________ _______IW II-SW2_______
Op Op Op Op Op Cl Op Op Op Op Cl Cl N/A N/A
1 2 3 4 5 6 7 8 1 2 3 4 5 6
Off Off Off On Off On On On Off Off On On Off Off MODEM/TERM jumper
1 2 3 4 5 6 7 1 2 3 4 5 6 7 block to TERM
NOTE: Dip switches 2-5 and 2-6 on the printer are preset at the factory.
They control the timing of the firing of the hammer. Do not move these
switches unless a hammer firing adjustment is being done. Refer to ImageWriter
II Technical Procedures for more information.
4.2 Remove all peripheral cards from the IIe. Install the Super Serial
card in slot 1. Connect the IW II to the S/S card via 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.
Type the program exactly as shown below.
20 FOR A = 1 TO 100
30 FOR I = 32 TO 126
40 PRINT CHR$(I);:NEXT I:PRINT
50 NEXT A
4.3 After you type RUN and press the <RETURN> key. The printer should
print out about 100 character sets like the one shown below. If it does,
the IW II is OK.
If it doesn't, look below for problems.
* If you get a SYNTAX ERROR on the computer, you may have mis-typed a
To correct the syntax error perform the following:
(1) Type LIST and press <RETURN>. The program should appear on the
(2) Examine the program for accuracy. Spaces, colons, etc. are
(3) To correct a line, simply retype the line and press <RETURN>.
LIST again to make sure the correction is OK.
* If nothing happens on the printer or the computer, press the RESET
key while you press the CONTROL key. Then LIST your program as
described above in the SYNTAX ERROR explanation to look for typing
* If no syntax errors occured; the cursor is blinking again; then the
program has probably run OK so there must be a problem with the printer.
