Troubleshooting Process Preliminary Operating Checks Prior to troubleshooting a specific printer problem, ensure that the following conditions are met: • The printer is plugged in and power is present in the outlet at the proper voltage. • The selected paper tray contains media and has been properly loaded. • The toner cartridge is installed properly. • The printer is being maintained on a regular basis as described in "Printer Maintenance" (page 57). • Any I/O devices are properly installed. • The customer is using acceptable paper as specified in "Media Troubleshooting" (page 129). • The printer is positioned on a solid, level surface. • The line voltage does not vary more than 10% from the nominal rated value as specified on the Power Rating Label. • The operating environment for the printer is within the temperature and humidity specifications listed in of this manual. • The printer is never exposed to ammonia fumes such as those produced by diazo copiers or office cleaning materials. • The printer is not exposed to direct sunlight. • Non-HP components (such as refilled Toner Cartridges, font cartridges, and memory boards) are removed from the printer. NOTE: Sudden changes in the printer's environment can cause image defects and paper handling problems. Always make sure the printer is not exposed to direct sunlight, heating or cooling vents. Allow time for the printer and media to acclimate whenever changing environments (for example, moving it from a cold environment to a warm one). Acclimation can take anywhere from 3 to 24 hours depending on the ambient conditions. Basic Fault Isolation The troubleshooting process is a systematic approach that addresses the major problems first, then other problems as the causes for printer malfunctions and errors become apparent. "Troubleshooting Process Flow" (page 92) illustrates the major steps for troubleshooting the printing system. Each heading depicts a major troubleshooting step. A YES answer to the questions allows one to proceed to the next major step. A NO answer indicates that additional testing and correction is needed. Proceed to the referenced location in the chapter and follow the directions for that area. After completing the additional testing and correcting the problem, proceed to the next major step. 90 Chapter 6 Troubleshooting C4170-90959

Troubleshooting Process
Preliminary Operating Checks
Prior to troubleshooting a specific printer problem, ensure that the following conditions are
met:
•
The printer is plugged in and power is present in the outlet at the proper voltage.
•
The selected paper tray contains media and has been properly loaded.
•
The toner cartridge is installed properly.
•
The printer is being maintained on a regular basis as described in “Printer Maintenance”
(page 57).
•
Any I/O devices are properly installed.
•
The customer is using acceptable paper as specified in “Media Troubleshooting”
(page 129).
•
The printer is positioned on a solid, level surface.
•
The line voltage does not vary more than 10% from the nominal rated value as specified
on the Power Rating Label.
•
The operating environment for the printer is within the temperature and humidity
specifications listed in of this manual.
•
The printer is never exposed to ammonia fumes such as those produced by diazo
copiers or office cleaning materials.
•
The printer is not exposed to direct sunlight.
•
Non-HP components (such as refilled Toner Cartridges, font cartridges, and memory
boards) are removed from the printer.
NOTE:
Sudden changes in the printer’s environment can cause image defects and paper handling
problems. Always make sure the printer is not exposed to direct sunlight, heating or cooling
vents. Allow time for the printer and media to acclimate whenever changing environments (for
example, moving it from a cold environment to a warm one). Acclimation can take anywhere
from 3 to 24 hours depending on the ambient conditions.
Basic Fault Isolation
The troubleshooting process is a systematic approach that addresses the major problems
first, then other problems as the causes for printer malfunctions and errors become
apparent. “Troubleshooting Process Flow” (page 92) illustrates the major steps for
troubleshooting the printing system. Each heading depicts a major troubleshooting step. A
YES answer to the questions allows one to proceed to the next major step.
A NO answer indicates that additional testing and correction is needed. Proceed to the
referenced location in the chapter and follow the directions for that area. After completing the
additional testing and correcting the problem, proceed to the next major step.
