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
au
tomatically 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
inf
ormation 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.
