Turning On the Fluid System When Bypassed
To turn on the fluid system when it has been bypassed, press CLEAN
PRINTHEAD. The CLEAN PRINTHEAD light flashes during the cleaning
cycle and then goes off. The STANDBY light goes out when the clean
cycle stops. The operator must press STANDBY to power up the system
for operation.
You may want to print a test pattern to ensure that print quality is
satisfactory (See Chapter 3, "Troubleshooting".)
Idle Time Guidelines
You can leave the printer on indefinitely without printing; however, if
leaving the printer idle for more than 1 hour, you can extend ink life by
