ImageWriter: First Printed Line Squeezed Into 1/2 Line


PROBLEM DESCRIPTION: When print is initiated, the text of the first line is
compressed.

CAUSE: When you tear paper from an older printer, the platen gears may be
pulled 1/2 line or so out of alignment -- so that they are between two sprocket
positions. This is a normal occurrance and doesn't mean that the printer is
broken. During the print head's first pass after this has occurred, the platen
will not be positioned properly. At the next pass (the printer may perform
several passes for one line of print), the Line Feed motor is activated which
turns the platen causing the platen gears to realign for the rest of the print.

CURE: Before printing, turn off the printer and then turn it back on again.
This will cause the printer to perform its power-on initialization cycle which
activates the Line Feed motor, thereby realigning the platen gears before the
print is initiated.
