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.
