HP Pro 4300 C9H70UT C9H70UT#ABA Running the cleaning page automatically, Cleaning spilled toner

	Running the cleaning page automatically
	Use the following procedure to set the printer to print cleaning pages automatically at an interval
	that you select. In order for the cleaning page to run without intervention, you must keep the
	selected size and the plain paper type available in the printer. The printer will not interrupt a
	printing job in process to run a cleaning page.
Note	HP recommends that the cleaning-page interval be set at 2,000 pages (or fewer) to make sure that
	excess toner is removed from the printer. This ensures good print quality.
	If you have an optional duplexer installed, make sure that automatic cleaning option is turned not
	selected. Run cleaning pages only manually. See “Running the cleaning page manually” on
	page 56.

Cleaning spilled toner

Defective or worn print cartridges can develop leaks. Also, after a jam has occurred, some toner might remain on the rollers and guides inside the printer. The pages that print immediately after the jam might pick up this toner.

Clean spilled toner with a cloth that has been dampened with cold water. Do not touch the transfer roller with the damp cloth or with your fingers. Do not use a vacuum cleaner unless it is equipped with a micro-fine particle filter.
