Identifying simple printer hardware faults.

1. Paper jams: If the printer is constantly getting paper jams, it could be due to misaligned paper trays, dirty rollers, or damaged paper feed mechanisms.

2. Poor print quality: If the prints are coming out faded, streaked, or blurry, it could be due to low ink or toner levels, clogged print heads, or dirty printer components.

3. Error messages: If the printer is displaying error messages, it could indicate a problem with the printer's hardware components, such as the fuser unit, imaging drum, or toner cartridge.

4. Connectivity issues: If the printer is not connecting to the computer or network, it could be due to faulty cables, outdated drivers, or a malfunctioning network card.

5. Strange noises: If the printer is making unusual noises, such as grinding or squeaking sounds, it could indicate a problem with the printer's internal mechanisms, such as the gears or motors.
