Extending Life of Thermal Inkjet Printheads for Commercial Applications
  DOI :  10.2352/ISSN.2169-4451.2002.18.1.art00025_1  Published OnlineJanuary 2002

Thermal Inkjet is a relatively new technology compared to other most commonly established in commercial applications like offset or electrostatic. Thermal Inkjet is wrongly viewed as an unreliable technology. It is usually perceived more suitable for low cost home device appliances. In the present paper, we introduce some of the data showing current trends in thermal inkjet performance and life.In the area of nozzle health measurement, noticeable progress has been seen with optical and electrostatic devices capable of measuring a single nozzle in less than 2 ms. Such high throughput enables a higher nozzle health monitoring frequency that helps in understanding how nozzle performance varies with time.Error hiding techniques in multi and single pass printing are also explained along with its potential reliability benefits. Higher nozzle packing capabilities that bring higher printhead resolutions can offer highly reliable systems in single pass printing, very suitable for Commercial Applications.In summary, nozzle health information can be used to improve noticeably error hiding algorithms and to apply better nozzle recovery algorithms, extending effectively printhead life.
