Setting Page Count, Maintenance Count,
and Serial Number
The page count, maintenance count, and printer serial numbers are stored
in Non-Volatile Memory. PAGECOUNT is the total number of images printed
by the printer, MAINTCOUNT is the pagecount when the next preventive
maintenance should be performed (every 350,000 images) (250,000 images
with HP LaserJet 5Si Heavy Media printers), and S.N. is the printer serial
number (also located on the printer back cover).
If it is necessary to replace the Formatter PCA, these numbers should be set
to the current values to accurately reflect the age of the print engine. The
procedures for setting these values are listed in Table 3-15.
Before removing the old Formatter PCA, print a PCL or PostScript
Configuration Page to verify the current values, if possible.
Note
If it is not possible to print a PCL Configuration Page, try to verify the
values before replacing the Formatter PCA by following steps 1 through 3,
below.
After verifying the page count, maintenance count, and printer serial
number from the old Formatter PCA, replace it with the new PCA.
