RELEASING/REPLACING THE PRINT HEAD
The print head on the printer is a user-replaceable item. If it becomes damaged for any reason, it can be
easily removed and replaced. Contact your local SATO representative for information on obtaining a
new print head. You will also need a No. 2 Phillips screwdriver (a magnetic tip is helpful) for the
replacement procedure.
1. Make sure the printer is OFF, and remove the power cable.
2. Lift up the Top Cover.
3. Locate the small center tab (see red arrow) above the print head.
Press and hold down this tab. At the same time, pull the whole print
head below it, downwards if it does not drop downwards automati-
cally.
The cable connector (circled red here) at the rear of the print head is now
exposed. Pull the print head downwards, then gently disconnect the print
head from the cable.
4. Carefully attach a replacement print head to the cable connector.
The connectors are keyed so that they can only be inserted in the
correct orientation.
Note:
While handling the print head, be careful not to scratch the printing
surface of the print head. Scratching the surface will cause perma-
nent and irreparable damage that is not covered by the warranty!
5. Reinsert the print head into the printer, making sure that the metal
slots at the two sides of the print head fit back over the round pur-
ple pivots on the printer (see circled area here).
6. Press and hold down the center tab (see red arrow) which was pre-
viously used to release the print head. Push the print head
upwards so that it snaps into place.
7. Release the center tab and close the Top Cover. Proceed to per-
form a test print to ensure that the print head is connected properly.
