System Error Codes - Full Descriptions

System Error: 71:19

Problem

Description:

Default Serial Number found in the main and backup NVM.

It seems that both the Formatter and PrintMech PCA (T1100/T1100ps/

T610

) or Media Advance Encoder PCA (T1120/T1120ps) have been

replaced together, or a previously used Printmech PCA or Media Advance

Encoder PCA was installed.

Recovery on page 3-51.

inform

ation:

Unauthorized upgrades

To prevent unauthorized upgrades of printers to a superior model, the new

rmware has changed the initialization process of the printer.

Location of the Serial and Product numbers

The serial number and the product number information is stored in two

locati

ons, in the EEROM of the Printmech and the EEROM of the Formatter.

Old initialization process

1 In the

previous initialization of the printer, the serial numbers and product

umbers were compared in the EEROM of the PrintMech PCA (T1100/

T1100ps/T610) or Media Advance Encoder PCA (T1120/T1120ps) and

the ERROM of the Formatter. If there was a difference, the printer displayed

SE 71:19.

2 T

he 71:19 recovery procedure could then be performed. This enabled

yone to do one of the following, possibly resulting in an unauthorized

upgrade:

 Input a serial number and product number into the PrintMech PCA

(T1100/T1100ps/T610) or Media Advance Encoder PCA (T1120/

For T1100/T1100ps/T610 printers, the backup NVM is

located in the Printmech PCA.

For T1120/T1120ps printers, the backup NVM is located in

the Media Advance Encoder PCA.

In all T Series printers, the main NVM is located in the

Formatter service part.

You MUST NEVER replace both the Formatter and the

PrintMech PCA (T1100/T1100ps/T610) or Media Advance

Encoder PCA (T1120/T1120ps) at the same time. If both

parts need to be replaced, you MUST first replace one part

and then power ON the Printer until it completely

initializes. Then you can power OFF the Printer and replace

the other part.

Never install a previously used PrintMech PCA (T1100/

T1100ps/T610) or Media Advance Encoder PCA (T1120/

T1120ps) into another printer.
