1.4.3 Cleaning the Platen
To clean the platen, follow these steps:
8 Locate a new print head assembly. Install the power and interface cables into the print head
assembly.
IMPORTANT!
The Unimark ET6000 printer uses the same newer version thermal print head now installed in
most of our Unimark 8500 bag tag printers. See “Replacing the Thermal Print Head” on
page 38 for more information on the new print head installed in Unimark 8500 printers.
9 Using the two alignment pins to position the print head assembly, place the assembly into the
mounting position.
10 Hand-tighten the two thumbscrews (turn clockwise to secure).
11 Power on the unit. Take the unit offline by pressing the ONLINE key.
12 Press Enter and then either the UP or DOWN arrow until SERVICE MENU appears. Press
Enter. Enter the service password (UP/DOWN arrows change the individual character value
and RIGHT/LEFT arrows move cursor side to side). Press Enter.
13 Press the UP or DOWN arrow key until the MAINTENANCE menu appears. Press Enter.
14 Press the UP or DOWN arrow key until the NEW PRINT HEAD option appears. Press Enter.
The unit will read the baseline resistance of the print head you just installed. After the baseline
resistance has been read, press ONLINE to put the unit back into service.
