Final answer:
The next step in the troubleshooting process for a failing laser printer that cannot pull paper from the input tray is to check the paper pickup rollers. These rollers may be dirty or worn out and need cleaning or replacement.
Step-by-step explanation:
The next step in the troubleshooting process for a laser printer that was failing to pull paper from the input tray would be to check the paper pickup rollers. These rollers are responsible for feeding the paper from the tray into the printer. If the rollers are dirty or worn out, they may not be able to grip the paper properly and pull it into the printer.
To check the paper pickup rollers, the technician can open the printer's rear access door and visually inspect the rollers. If they appear dirty or worn, they can be cleaned with a lint-free cloth dampened with water or isopropyl alcohol. If the rollers are severely worn, they may need to be replaced.
By checking and, if necessary, cleaning or replacing the paper pickup rollers, the technician can ensure that the printer is able to properly pull paper from the input tray, resolving the issue that was initially reported.
