PROBLEM DESCRIPTION: ImageWriter prints OK during Self Test. When a Macintosh
is used with certain software, the first several lines also print OK, but after
about a quarter of a page is printed, the ImageWriter pauses, and then prints
garbage.
CAUSE: The application may be using DTR handshaking flow control protocol (for
more infor search on HTS and FLOW CONTROL). If so, it needs pin 20 DTR from
the IW to be connected to pin 7 on the Mac.
CURE: Check the cable for 5 pins. If it doesn't have 5 pins, chances are DTR
from the IW is not connected to the Mac so the application doesn't know when
the IW's print buffer has filled. If the cable doesn't have 5 pins, obtain
cable P/N 590-0169. Also confirm that IW DIP switch SW2-3 is open to select
DTR handshake. If problem still not found, search on ImageWriter General
Troubleshooting.
