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?
Clean the inkjet nozzles.
Reinstall the printer drivers.
Perform another round of regular printer maintenance.
Refill the toner cartridge.
Replace the fuser unit.
Inspect the toner cartridge for proper installation and potential defects.
