The correct answer is A. Clean the developer tank.
The developer tank is a component of a laser printer that contains a magnetic roller and a toner cartridge. The magnetic roller attracts the toner particles, which are then transferred to the paper by the print head. If the developer tank is dirty, it can cause the print to be dirty as well. To clean the developer tank, you will need to remove it from the printer and clean it with a mild detergent and water. You can also use a vacuum cleaner to remove any dust or debris from the tank.
Option B, resetting the printer, is not likely to correct the problem of dirty print. Resetting the printer will only clear the printer’s memory and restore it to its default settings. It will not clean the developer tank or remove any dust or debris from the printer.
Option C, running several blank pages, is also not likely to correct the problem of dirty print. Running blank pages will only help to remove any excess toner from the printer’s print head. It will not clean the developer tank or remove any dust or debris from the printer.
Option D, cleaning the laser diode, is not a feasible option for most users. The laser diode is a delicate component that is located inside the printer. It is not recommended to attempt to clean the laser diode yourself, as you could damage the printer.
Option E, none of the above, is also not the correct answer. Cleaning the developer tank is the most likely solution to the problem of dirty print.
