Formatter Assembly Setting Page Count, Maintenance Count, and Serial Number The page count, maintenance count, and printer serial number are stored in Non-Volatile Memory. PAGECOUNT is the total number of images printed by the printer, MAINTCOUNT is the page count when the next preventive maintenance should be performed (every 350,000 images), and S.N. is the printer serial number (also located on the printer back cover). CAUTION DIMMs and the Formatter PCA can be damaged by small amounts of electrostatic discharge (ESD). Wear an anti-static wrist wrap.
If it is necessary to replace the Formatter PCA, these numbers should be set to the current values to accurately reflect the usage of the print engine. The procedures for setting these values are listed in table 3-12 on page 76. Before removing the old Formatter PCA, print a Configuration Page to verify the current values. Note If it is not possible to print a 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. 1 Enter Service Mode as described in “Service Mode” on page 75.

Note The page count interval can be changed to a value less than 350, 000 for special media situations. 196 Chapter 6 Removal and Replacement C4085-91087
