T1120ps) and Formatter EEROM.

„Choose which EEROM held the correct information, and copy it across to the other EEROM.

 

New initialization process

 

From firmware 7.x.x.x onwards, the information is now always copied

 

automatically from the EEROM in the PrintMech PCA (T1100/T1100ps/

 

T610) or Media Advance Encoder PCA (T1120/T1120ps) to the EEEROM

 

in the Formatter.

 

This means that the printer will now take on all the attributes of the

 

information located in the PrintMech PCA (T1100/T1100ps/T610) or

 

Media Advance Encoder PCA (T1120/T1120ps), possibly rendering the

 

printer unusable. The following are just a few examples of why this could be

 

possible.

 

„ The printer may not be able to fully initialize if there is a mismatch

 

between the size of the printer and the size in the EEROM of the

 

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

 

PCA (T1120/T1120ps).

 

„ The PostScript capabilities of the printer could be affected.

 

„ All the calibrations applied from the factory will be copied, so incorrect

 

calibrations could be applied to the printer.

 

How to resolve serial/product number errors

 

Any issue will need to be escalated through your local support organization

 

if:

 

„ A reused PrintMech PCA (T1100/T1100ps/T610) or Media Advance

 

Encoder PCA (T1120/T1120ps) has been accidentally installed

 

„ Both the PrintMech PCA (T1100/T1100ps/T610) or Media Advance

 

Encoder PCA (T1120/T1120ps) and the Formatter have been installed

 

at the same time in error.
