Ultra electronic Sprinter manual Removing old printhead/assembly

2. Removing old printhead/assembly

(1)Remove the dye-film and dye-film carrier from the printer.

(2)If a tye-wrap is fitted to the grey ribbon cable plug on the back of the printhead, cut this tye-wrap taking great care not to cut the ribbon cable itself.

(3)Disconnect both cables from the printhead.

N.B. Before removing the printhead assembly completely from the printer, take careful note of how the two springs are attached at the rear and each side of the assembly.

(6)Using both hands, hold the printhead assembly at each side by the nylon brackets, and move it upwards. Note : as the assembly disengages from the chassis cover, the two springs will push it forwards and care must be taken not to lose the springs as the printhead is lifted clear.

(4)If a head bar is fitted, remove the securing screw at each end and lift away the head bar. This should leave the earthing strap loose at the right hand side of the chassis cover.

If no head bar is fitted, disconnect the earthing strap from the reatining screw at the left hand side ot the printhead assembly

(5)Disengage the two lugs at the ends of the two nylon side brackets by spreading apart the legs of the nylon brackets until the lugs just clear the chassis cover, swing them forwards and allow them to rest against the leading edge of the chassis cover.

(7)Place the printhead assembly on a bench with the printhead and its labels at the bottom. Undo and remove the printhead pivot screw (see diagram) and its two washers .

(8)Slide the printhead backwards (plugs first) out of the heatsink.
