Note: Many of the 930-938 are communication failures between the printheads and the carrier contacts as noted. If contact failures are suspected, check alignment between the pogo pins and printhead tab circuit. This can be done by lightly placing a piece of low tack tape on the printhead tab circuit and inserting it in the carrier. If contamination is suspected, remove the printhead and clean the contacts with a low-lint damp cloth. Clean the pogo pins only with a clean, lint-free cloth. Diagnostic Information 2-5
