Troubleshooting

The message <MEMORY FULL> or <MAKING SPACE IN MEM> appears in the LCD when making copies of a multiple page document.

Cause 1	Paper in the paper drawer or stack bypass may have run out.
Remedy	If there is no paper and the machine’s memory becomes full during copying, the
	messages <MAKING SPACE IN MEM> and <SUPPLY REC. PAPER> are displayed
	alternately. If paper is loaded, the copying resumes automatically.
Cause 2	The document you are copying may have too many graphics or photos.
Remedy	When making copies of such documents, separate the documents into smaller stacks
	or feed them one by one.
Cause 3	The machine’s memory is full.
Remedy	Print or delete any documents stored in memory to free up space in the machine’s
	memory, then start again. (See Chapter 5, “Special Sending and Receiving Features,”
	in the Facsimile Guide).

Documents have black streaks or appear dirty after you feed them in the ADF.

Cause	The ADF roller is dirty.
Remedy	Clean the ADF roller. (See “Cleaning the ADF Roller,” on p. 5-17.)

Print Quality Problems

The print quality is not what you expect; print is not clear, has missing dots, or white streaks.

Cause 1	The size, thickness, and type of the paper you are using are not within the
	specifications of the machine.
Remedy	Check that the paper you are using is supported by the specifications of the machine.
	(See “Paper Handling,” on p. 5-2.)
Cause 2	The toner cartridge may not be installed properly.
Remedy	Make sure the toner cartridge is installed properly.
Cause 3	The toner in the toner cartridge may be low.
Remedy	Replace the toner cartridge if necessary. (See “Replacing the Toner Cartridge,” on
	p. 5-19.)
Cause 4	The copy exposure may not be adjusted correctly.
Remedy	Adjust the exposure correctly. (See “Copy Exposure Adjustments,” on p. 3-12.)
