A client calls to report that the documents from their high-volume laser printer have started showing faded print on the right side, while the left side is printing normally. The printer was recently serviced and had its toner replaced. Before considering a hardware replacement, which of the following should be investigated FIRST to address the faded print issue?
Replace the fuser unit.
Refill the toner cartridge.
Perform another round of regular printer maintenance.
Clean the inkjet nozzles.
Inspect the toner cartridge for proper installation and potential defects.
Reinstall the printer drivers.
