Go to the Special function menu (page 3-11) and perform the
following:
1. Select Toggle Demo mode by double pressing the operator
panel button until the Ready and Load Paper lights are on.
2. Perform a long button press until all lights are on solid.
Print registration adjustment
• Adjust the left margin until the registration box illustrated on the
diagnostics test page is centered on the page.
• Adjust the top margin until the registration lines located at the
bottom of the diamonds at the bottom of the page fall on the
bottom edge of the page.
These settings may be modified by issuing PJL DEFAULT
commands when the printer is in normal mode. The PJL variables
used to describe registration are LLEFTMARGINOFFSET and
LTOPMARGINOFFSET.
Factory defaults
When the printer is initialized, the printer environment returns to
default settings.
There are of two types of default settings:
• Fixed default settings cannot be modified from their factory set
values.
• Variable default settings can be altered from their factory set
values. Factory set values are never erased and may be
restored at a later time.
