Epson 8900 Series manual Paper motion is reversed

qValid Z-axis adjustment values are 00 through 99 from the automatic Z-axis initialization adjustment (00) in positive or negative directions (-99 through +99).

qNote the location of the Z-axis initialization whenever paper stock is changed or tractors are moved, to determine the 00 calibration and corresponding number of sheets and form thickness.

qZ-axis adjustments are not cumulative; each Z-axis adjustment escape sequence is independent from previous adjustments in the escape sequences referenced only to the 00 automatic calibration.

qPositive displacement moves the printhead away from the platen.

qThe direction of printhead initialization displacement is positive. To clear backlash, this requires that a negative displacement be followed by positive displacement unless the adjustment for Z-axis is reinitialization.

qThe range of the printhead Z-axis adjustment from the control panel is -5 through +20 from the Z-axis initialization adjustment.

qEach Z-axis adjustment requires that the printhead stop and therefore acts to decrease throughput. Forms format and printing format are both considerations to maximize throughput.

qAvoid a format that prints columns on either side of a label. If printing a column is required, print the column first (but only to the bottom of the label), adjust the printhead Z-axis while reversing paper motion, and then print the label.

!	Caution: Care must be taken that a label is not peeled when
	paper motion is reversed.
