Setting the Page Count, Maintenance Count,
and Serial Number
The page count and printer serial number are stored in non-volatile
memory. If it is necessary to replace the Formatter PCA, the page
count should be set to the current value to reflect the age of the Print
Engine. The procedure for setting the serial number is similar to
setting the page count.
Note Before replacing the Formatter PCA, print a Configuration Page to
verify the current page count and serial number of the printer, if
possible. Use the information on the Configuration Page to reset the
page count and printer serial number for the new Formatter PCA.
