area where Head will sit for any debris such
as dried ink. Clean with Solvent (SPC-0336)
if neccessary.
2-5. Grasping damper projection, place
Head in position. Install, but do not tighten
the front and rear hex screws.
2-2. Fill syringe with 6-8 cc of S-Head
Replacement Solution. Inject approx 3-4 cc
into each Damper Insertion Projection over
a period of about 30 seconds. Head can be

that they are seated correctly. A cable seat-
ed at and angle may short out, damaging
cable and head! Lower Damper Holder into
