2.1 ENGINE FUNCTIONS
2.1.1 IMAGE DATA PROCESSING
The controller uses the engine's FCI (Fine Character Image) function for smoothing
and toner saving mode, but these two functions do not work at the same time.
When toner saving mode is enabled, edge smoothing is automatically disabled.
The memory circuit in the engine (MSU) is not used for printing from the controller.
2.1.2 PRINT PRIORITY AND INTERLEAVING
[User Tools] – [System Settings] – [Print Priority] defines how the copy, fax and
printer applications share a single print engine.
NOTE: "[User Tools] – [System Settings] – [Print Priority]" indicates that you press
the System Tools key, select System from the menu, then select "Print
Priority" from the next menu.
Display Priority
A print request from the application (copy, fax, or printer) now displayed on the
LCD has the highest priority. For example, the machine is in the middle of a large
copy run, and a user wants to print a document from a computer immediately. In
this case, pressing the Printer key to switch the LCD display to Printer mode will
interrupt the copy run and print the document from the computer, and the copy run
will resume after the document has been printed. If the LCD display stays in Copy
mode, the user will have to wait until the copy run finishes.
Note that the Interrupt key on the operation panel does not work like the Printer key
in the above example. The Interrupt key is for interrupting a copy run to do another
copy operation.
Copier, Fax or Printer
The selected application has the highest priority, regardless of which mode the
LCD is in. If there are multiple print requests to the print engine, the selected
application will print first. Other applications have to wait until the selected
application finishes printing.
