• ST Models: Raise the

access cover; see

Ž Slide the Printhead

Latch to the Unlocked

Printhead Assembly.

•Gently clean the Printhead, including the Burnline, using a cotton swab moistened with isopropyl alcohol to remove all build-up.

•Allow to dry; then lower the Printhead Assembly and slide the Printhead Latch forward to the Locked position.

‘ST Models: Close the access cover.

’Plug in and turn ‘On’ the printer.
