replaced.

loaded correctly into the Document
Tray.

installed properly.

MEMORY FULL Appears on the LCD When Making Multiple Copies
Cause

Error Correction Mode (ECM) sending/receiving should eliminate such
problems. However, if the telephone lines are in poor condition, you may
have to try again.
Lower the reception speed (see RX START SPEED on page 52).
The sending fax machine usually determines the quality of the document. Call
the sender and have them make sure their fax machine is functioning properly.
If the sending fax machine does not support ECM, then the document is
received in normal mode without error checking.
Make sure ECM is on (see ECM RX on page 51).
Lower the reception speed (see RX START SPEED on page 52).
Call the sender and have them check that their fax machine is functioning
properly.
Determine if the problem is with the FINE Cartridge and replace if necessary
(see page 56).
Remove the document, stack it if necessary, and load it face up into the
Document Tray correctly (see page 16).
Make sure the Printer Cover is closed.
Make sure the FINE Cartridge is installed properly (see the Easy Setup
Instructions).
Print the nozzle check pattern (see page 59).
Print or delete any documents stored in memory (see page 36) to free up
space in the fax's memory, then start again.
Change the scanning resolution and try copying again.
If multiple pages are being copied, separate the pages into smaller stacks. If
not, make the desired number of copies one at a time as needed.
