Maintenance interval: as needed.
If you discover that an excessive number of jets are out on a
printhead (after cleaning or printing the prime bars or other
test), you can attempt to recover jets by performing a manual
prime.
This procedure requires a special priming bulb, included with
the printer. Each prime will expel approximately 1 ml of ink. To
keep ink counting as accurate as possible. you will report the
number of primes to the printer via the control panel.
1. From the control panel Front Page screen, press the Prime
key.
2. Open the service station access door.
3. Insert the priming bulb into one of the priming access holes
in the top cover of the carriage.
