3. INTRODUCTION
•The printer which use electrical charges in its operation is called Inkjet
Printer.
•The minute jets of ink are used to form character on the paper
•Printing speed 6 pages per minute
•Mostly used to develop photo

4. The world firstinkjet printerwasinventedby Ichiro Endo

5. PRINCIPAL
•A charged particle is deflected when passesthrough uniform electric
field between two oppositely charged parallel plates.

6. INSTRUMENTATION
•Ink reservoir
•Pump
•Nozzle
•Charging tunnel/electrode
•Charging control
•Deflecting plates
•Gutter

7. WORKING
•Working
•Ink reservoir
•Contain ink plenty much
•Supply ink on demand
•Pump
•Middle man
•Suck ink from reservoir and supply to ink nozzle
•Ink nozzle
•Made of pieziotropicelement
•Made fine minute particle of ink
•Charging tunnel
•It charges the minute ink particle that are not required to print
•Required particle remain uncharged and passes safely thoroughly deflecting plates and stick
with paper

8. WORKING
•Charging control
•It control the charging tunnel
•It gets its command from computer
•Deflecting plates
•When charged particle pass through these plates these are deflected toward gutter so
no image formation occur
•Gutter
•Collect deflected ink particaland send them back to ink supply
