In an office photocopier user guide, it is written: 'To replace toner, open the front cover, pull the old toner cartridge out, shake the new cartridge gently 5-6 times, insert the new cartridge until it locks, then close the front cover.' An administrative staff member follows all steps but forgets to shake the new toner cartridge. What problem will the staff most likely encounter after replacing the toner?

The printed output will appear blurry or uneven due to the sub-optimal distribution of toner powder inside the cartridge.

A mechanic at an automotive workshop has a routine maintenance schedule for the school bus fleet. One maintenance instruction reads: 'Brake and steering system inspections must be performed every 10,000 km or every 6 months, whichever comes first.' Bus A was last inspected at 85,000 km (on January 1st) and now the mileage is 92,000 km (on July 1st). When is the next brake inspection for Bus A?

Perform the inspection immediately because the 6-month time limit has already been reached regardless of the mileage.
