Other control panel features
The control panel of your printer also gives you access to several
special functions.
Self test:
Micro-adjustment: By pressing the FORM FEED button immediately
Data dump:
Both a draft and Letter Quality self test function
are built into the printer. The self test printout
lets you check the current DIP switch settings
and operating status of the printer. You can start
the printer's self test by holding down the LINE
FEED button or the FORM FEED button while
turning on the printer. See the section on the self
test in Chapter 1 for more information.
after loading paper or when using short tear-off,
you can make fine adjustments to the loading
and short tear-off positions. These positions can
only be adjusted while the MULTI-PART light is
blinking. See the sections on adjusting the
loading position and using the short tear-off
function later in this chapter.
By holding down both the LINE FEED and FORM
FEED buttons while you switch on the printer,
you turn on the data dump mode. This feature
allows advanced users to locate the source of
communications problems between the
computer and printer. See the section on using
the data dump mode on page 3-24 for more
information.
