Issue 2 41 Part No. Issue 2 43 Part No. Issue 2 45 Part No. Top Cover The top cover 5 is moulded from a plastic material and houses the following: The control panel 3. A hinged reservoir filler cover 1 that gives access to the ink and top up reservoir fillers. A vent 2 that allows heat and vapour to escape from the enclosure.

The top cover is secured in position by two fasteners 4 which are screwed in to release the cover. When raised, the top cover is supported on two telescopic struts, which gives access to the internal components of the printer.

Side Covers The two side covers 9 are similar, they have different length fasteners fixed to them, thus they require the correct orientation when fitting. The side covers should be fitted with the long fasteners at the opposite side from the printhead umbilical cable.

When the covers are removed the fasteners are retained in the cover by captive plastic washers. Base The base 10 is moulded from plastic and houses the following: The ink system filters see Ink System Filters, page 82 and the electronic system cooling fan filter. A hinged cover 8 , which gives access to the ink system filter and the electronic system cooling fan filter.

The bleed valve 18 mounted on the heater module block is normally closed, only opening during purging, flushing of the nozzle and start up and shutdown. The bleed valve when energised removes air from the feed and return pipework and the nozzle when being purged. A vacuum is also applied through the bleed valve to the nozzle during a nozzle flush. The ceramic transducer 11 is fed with a modulation signal.

The transducer causes the nozzle assembly to vibrate along its length so that the ink stream from the nozzle jet orifice is formed into individual droplets. The nozzle jet orifice 12 has a diameter of 60 microns. The LED is strobed at the modulation frequency so that the position of individual droplets can be observed with a magnifying glass x10 minimum.

The charge electrode applies an electrical charge to each individual ink droplet. The charge applied to the droplet is variable and affects the position of the droplet on the substrate. The deflector electrodes generate a constant electrostatic field through which the electrically charged ink droplets pass.

The charged ink droplets are deflected by the electrodes, the amount of deflection is dependent on the charge applied to the ink droplet. The gutter delivers the ink back to the ink system. The front cover protects the printhead components.

Removal of the cover is sensed by the printer via the cover switch 5. When the cover is removed the voltage to the deflector electrodes is turned off. It is open while printing and during the flushing cycle, but closes when the printer stops to prevent leakage from the nozzle. A signal return lead is connected to the other. When ink which is conductive is present, the signal passes through it to the return lead. A wiring diagram for the printhead electrical and ink systems is shown in Figure Issue 2 49 Part No.
