INCORRECT PAPER SIZE ↔ CASS PAPER MISMATCH

Cause

The size of the paper in the cassette or multi-purpose feeder is different from

 

that of the paper specified in <PAPER SIZE> in <COMMON SETTINGS> of the

 

Menu.

 

 

Remedy

Load the correct paper size or change <PAPER SIZE> in <COMMON

 

SETTINGS> of the Menu. (See "Loading Paper," on p. 2-4, or "Specifying the

 

Paper Size," on p. 5-3.)

 

Then reset the machine by opening the front cover and then closing it.

 

INSTALL CARTRIDGE ↔ TONER SUPPLY LOW

 

 

 

 

Cause

The cartridge is not installed or not installed correctly.

 

 

Remedy

Install the cartridge correctly. (See "Replacing the Cartridge," on p. 8-14.)

 

LOAD LTR SIZE PAPER

 

 

Cause

No LTR-size paper is loaded in the cassette or multi-purpose feeder.

 

 

Remedy

Load LTR-size paper in the cassette or multi-purpose feeder. (See "Loading

 

Paper," on p. 2-4.)

MEMORY FULL

PRESS SET KEY

Cause

The machine's memory is full because the collate copy function was set when a

 

large document is loaded.

 

 

Remedy

Divide the document and copy each part separately.

 

If <MEMORY FULL> and <PRESS SET KEY> appear while scanning

 

documents using the ADF, the document being scanned stops in the ADF. In

 

this case, press [Set] to make the document come out automatically.

 

PRINTER DATA ERROR

 

 

 

 

Cause

A problem has occurred in the data transmission between the machine and

 

your computer.

 

 

Remedy

Use System Monitor to delete the current print job.
