Replacing the PrintMech PCA, Media Advance Encoder
PCA and Formatter
IMPORTANT: Three rules for replacing these three service parts
 Never install a previously used PrintMech PCA (T1100/T1100ps/T610) or
Media Advance Encoder PCA (T1120/T1120ps/T620) into another
printer.
 Never install a previously used Formatter/Hard Disk Drive in any T Series
printer.
 You must never replace both the Formatter/Hard Disk Drive and the
PrintMech PCA (T1100/T1100ps/T610) or Media Advance Encoder PCA
(T1120/T1120ps/T620) 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.
