When USB is connected after 30sec of no communication through the
parallel port, the mode is shifted to the USB mode instantaneously.
If no communication state does not reach 30sec yet, shifting to the USB
mode is retained until 30sec passes. During that time, print jobs are
performed through the parallel port.

After completion of unfinished print jobs, if there is no communication for
30sec, shifting to the USB mode is made.
Within 30sec, print jobs are performed through the parallel port.

2. INSTALLING THE PRINTER DRIVER

(Description of the printer driver)

The printer driver is the software program which runs the printer. It con­verts the data in your file into information that the printer can under­stand. It also controls communication between the printer and
computer as the data is printed.

11) Attach the cover to the rear cabinet.
(1) Align the arrow marks as shown in the illustration.
(2) Then slide the cover to the left.
(3) Secure the cover with a screw.

Operational descriptions

Connected to PARACONN or USBCONN of PCL I/F PWB
(CPWBF0057QS51).
Print data made by page description language is inputted from an ex­ternal device.

The PCL I/F PWB (CPWBF0057QS51) is provided with two kinds of
connectors for external devices. The suitable connector is determined
according to the connection type with an external device as follows:

● An external device is connected to PARACONN, and not connected
to USBCONN.

→ Data sent from the external device connected to

PARACONN is printed.

● An external device is not connected to PARACONN, but connected
to USBCONN.

→ Data sent from the external device connected to USBCONN

is printed.

● An external device is connected to PARACONN, and connected to
USBCONN.

→ Data sent from the external device connected to USBCONN

is printed.
The external device connected to PARACONN is not recog­nized.

Data inputted to PCL I/F PWB is inputted to PCL PWB and PCL­decoded and converted to generate BITMAP data for print.

To generate BITMAP data for print, DRAM On board 8 MB and the ex­pansion RAM inserted into the 168 pin DIMM are used as the work
area.

BITMAP data generated in PCL PWB are subject to jitter adjustment by
M66236FP, and inputted to MCU PWB through Video CONN to per­form laser output and print.
