30. Situation HP has been investigating an increase in calls regarding toner dumping inside of the printer The investigation revealed three potential scenarios in which toner dumps It is imperative that the support partners thoroughly troubleshoot this condition in order to successfully complete the repair Scenario Number 1 Most likely scenario Toner cartridge usage may have exceeded the life of the cartridge A toner cartridge for the 5Si family of printers has a life expectancy of 15 000 images A toner cartridge that is used longer than 15 000 images can experience a failure due to wear on the photoconductive drum and on some mechanical components such as gears and seals This failure can cause some toner to leak into the printer In this scenario no printer parts are needed Refer the customer to proper usage Scenario Number 2 If the printer has a formatter revision that is earlier than 9 1 the engine may continue to run which causes dumping of the toner cartridge Verify that the version of the DC controller is a 1 11 version To do so refer to IC 201 on the DC controller the identifier is 02 Replace the DC controller if it is a 1 11 version Do not replace the formatter for this condition EN Technical Tips 219 Scenario Number 3 Least likely scenario The printer may be exhibiting a 79 Service 04CC error The 79 Service 04CC was added to the firmware code of formatters 9 1 version or greater to capture t
