3.5.4 Service Parameters
Press 9 4 FUNCT to display the following Service Parameters. These parameters are
factory set specifically for each printer and recorded on the configuration label behind the
display inside the printer. They do not usually need to be modified by the user.
If changes are made to these settings write the new setting on the configuration label.
CAUTION: CHANGE OF THESE PARAMETERS BY UNTRAINED PERSONNEL MAY
RESULT IN INCORRECT PRINTER OPERATION.
DISPLAY REMARKS
TOP OFFSET = XX
Adjusts the uppermost print line location. Smaller values print closer
to the top edge.
LEFT OFFSET = XX
Adjusts the carriage home location during document insertion. Larger
values move the carriage to the left.
LEFT MARGIN = XX
Adjusts the first column print position if edge sensing is not installed
(EDGE SENSOR parameter will not appear below). Larger values move
printing to the right.
CAR. ALIGN = XX
Aligns lines printed right to left with lines printed left to right. Larger
values move right to left printed lines to the left.

the distance moved.
REVERSE COMPENSATION
= XX
Adjusts distances moved up the document. Larger values increase the
distance moved.
EJECT HOLD OFFSET = XX

Sets the height of the alignment gate. Larger values raise the gate
higher.
NORMAL DARKNESS =

Adjusts darkness at normal print speed. Lower values reduce darkness
and increase ribbon life. Select the lowest value that provides suitable
legibility on thick forms.
CQ DARKNESS = -10 to 10
Adjusts CQ print darkness.
SET SKEW VALUES
SKEWCMP = -15 to 16
Value set by auto alignment skew sensor calibration. Compensates for
right document sensor position relative to left document sensor.
SET SKEW VALUES
MID-SKEWCMP = -15 to 16
Value set by auto alignment skew sensor calibration. Compensates for
middle document sensor position relative to left document sensor.
EDGE SENSOR = XX
Adjusts the first column print position from the left paper edge. Larger
values move printing to the right.
PRINTHEAD TYPE
Only displayed in early version DP8‟s with later firmware installed. Set
to match the printhead body color. Warning: A BLACK head can be
