Clear clogged jets
A clogged jet appears in the prime pattern as a gap in the “stair-step pattern”
for each cartridge. The printer does not automatically detect clogged jets, so
you must clear them manually by cleaning and priming the cartridges.

To clear clogged jets
1
Examine the printed test pattern.
2
Unsnap the ink cartridge which shows clogged jets from the carriage.
3
Prime the cartridge using the prime tool. To do so, attach the prime tool to the
cartridge jet plate and prime cartridge with pulses by pressing the activation
button repeatedly.

Clean the cartridge jet plate by blotting the jet plate with a distilled
water/isopropyl saturated lint-free towel.
Note:
For severely clogged cartridges completely clean the jet plate
thoroughly by immersing cartridge jet plate into ultrasonic cleaner for
30-40 seconds. As a final attempt, try immersing the jet plate into boiling
water for 10-15 seconds.

After cleaning, reinstall the cartridge.
