5.5 Troubleshooting within TCP/IP

The following hints should help you if trouble arises when using the

Print Server. If you experience additional problems, contact Patton
Technical Support M-F, 8:30 - 5:00 PM EST at (301) 975-1007.

General

No Power LED

1) Check that external power supply adapter is correct type and is

functioning correctly.

2) Ensure DC connector to the Print Server is seated correctly.

3) If you are relying only upon interface power on pin 18 of the

Centronics interface, be sure the output is 5 V DC (TTL Spec.).

Status Page Not Printed

1) The status page prints only within 30 seconds of power-up or when

forced by software (see Section 5.2.1)

2) The power-on status page option may be disabled (see Section

5.2.1)

3) The Postscript printer option may be set incorrectly for your printer

(see Section 5.2.1)

4) Your printer may have a large internal buffer, in which case the

status page may have spooled to your printer but is waiting for a
timeout or command in order to print. (Check your Printer manual.)

TCP/IP Specific

Print Server Will Not Respond To PING

1) Ensure the units Internet Address has been correctly set

Check the hosts ARP table is correct

5.4 Upgrading withinTCP/IP

To use the FTP based method of FLASH upgrade, it is firstly necessary
to establish an FTP connection to the Print Server in the same way as
that used when printing to the unit via FTP. Typically this will be
achieved as follows:

FTP xx.xx.xx.xx

where

xx.xx.xx.xx is the unit’s Internet Address

Once connection is achieved in this way, the Print Server will

respond with a prompt requesting the USER NAME to be supplied.
When printing to the unit, this field may be ignored but when preparing
to perform a FLASH upgrade, it is the response to this field that
indicates an upgrade is being performed. To continue with the upgrade
procedure, the user must enter:

pattonflashupdate

followed by carriage return. It is now necessary to transmit the new
operating system to the Print Server. The units new operating system
will be supplied on a single 3.5 inch diskette which will contain a single
file called IMAGEnnn.BIN (where nnn is the version number of the
upgrade). This file is typically transmitted to the Print Server using the
PUT command as shown below:

PUT IMAGE.BIN

Assuming that the file transfer was completed correctly, the Print Server
will respond to the end of transfer with the message:

FILE TRANSFER COMPLETE - Upgrade continues when FTP is quit

Quitting FTP will now cause the FLASH upgrade to occur, and after a
few seconds, the unit will reboot and begin operating using the newly
downloaded operating system.
