1500 TX User's Guide
Clogged jets
Clogged jets cannot be automatically detected and therefore must be cleared
manually. To clear a clogged jet, clean and prime the affected cartridge according
to the instructions on page 4-8 of the Users Guide. Your goal is to eliminate all
gaps in the "stair step" pattern before starting your job.
Electrically defective jets
Your 1500 TX automatically discontinues use of electrically defective jets and
instead uses other jets to compensate for them.
