Slight raggedness, sample test pattern

Ragged Print

General raggedness is most common problem encountered with 7122

printheads. Raggedness falls into the following three categories:

•

Slight - caused by dried ink buildup during normal operation

•

Serious - caused by contamination or lack of cleaning

•

Startup - caused by dried ink buildup on a shut down system.

Slight Raggedness

will cause slightly ragged print. The normal clean cycle should prevent it

(see "Standby Pan Installation" in Chapter 4, "Maintenance"). Persistent

raggedness may require swabbing. Figure 3.3 shows mild raggedness on

the upper portion of a test pattern run at 130 volts and 41 phase counts on

a printhead with 150 hours.
