Setting the Page Count The page count is stored in the printer’s non-volatile memory (NVRAM). If it is necessary to replace the formatter PCB, the page count should be reset to the printer’s original page count to reflect the age of the print engine. Before removing the old formatter PCB, print a self-test/configuration page to verify the current page count of the printer, if possible. See “Printing Self-Test/Configuration Page” (page 46) for information. Table 3-2. Setting the Page Count Via PJL Service Mode Commands Setting the Cold Reset Default The customization variable will determine the default paper size after a cold reset. This is set to A4/Letter at the manufacturer.
This variable may need to be reset when replacing the formatter. Table 3-3.
