ALIGNMENT & TEST

HA Print Gap

Scope:

This adjustment is used to set the nominal operating print gap (space between

printhead and platen). Performing this procedure may be necessary when replacing the

printhead, or experiencing light, missing and smearing print. This procedure is

completed when “HA Print Gap Down” (downward pressure), and “HA Adjust UP”

(printhead vs. platen gap) is adjusted.

Physical measurements (with feeler gauges) may not be necessary after restoring print

gap values found on the HA ADJUST label located inside the printer behind the

printhead carrier. Refer to page 10 for details. Use the following HA GAP ADJ DOWN,

HA GAP ADJ UP and Multi-part Print Gap procedures to restore label values.

Required materials:

 8.5X11 inch cut sheet paper

 .004 inch feeler gauge, one foot long

 .006 inch feeler gauge, one foot long

Procedure:

HA GAP ADJ DOWN

1. Select control panel AUTO print gap, and Cut Sheet modes.

2. With the printer power turned OFF, press and hold the LF and RLF keys while

turning ON the printer power switch. Hold keys until printer initialization (carriage

movement) is completed. The printer is now in “HA GAP ADJ DW” mode, the

current setting is displayed on the LCD (* indicates selection). Decreasing the

numeric value reduces downward carriage pressure.

3. Load a piece of cut sheet paper landscape orientation ( ) into the printer.

NOTE: failure to load paper in the landscape orientation will cause gap

discrepancy.

4. Press the ENTER key and verify the print gap is electronically confirmed in two

positions across the platen. Print gap is established when the printhead moves

down and up vertically.
