surfaces, and telephones are not acceptable grounding points. The

printer isn't an acceptable grounding point either because it must be

unplugged before you perform this task.

If you don't have an anti-static wrist strap, discharge your body's

static electric charge by touching a grounded surface before you

handle any printer boards or components and before removing the

tray assembly cover. Redischarge your body each time after walking

around and before touching the printer tray assembly again. Handle

the tray carefully, and try to handle it by the edges only.

1 Remove the printer controller board.

Instructions are in the section called “Removing the Controller

Board” in the Options chapter of your printer documentation.

2 If the controller board has no daughterboard installed, skip

to step 3. If the controller board does have a daughterboard

installed, detach it from its connectors and support posts

and put it aside.
