Print Quality Problems - Canon IMAGERUNNER 1610 Reference Manual

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.
