Troubleshooting
Verifying print engine operation by using its test print
1.
If not already on, turn on the printer. If the printer does not begin
initializing, go to the topic, “Verifying power supply operation”
below.
2.
Once the
Power
light is on (not blinking) and the front panel displays
Ready
, press the
Menu
button and scroll to the
Startup page
. menu
item and then press
.
The printer should print out a test print.
If the printer prints a test page, then the print engine is working correctly. If the
printer does not print a test print, then a problem exists with the print engine.
Proceed with the topic, “PC-based diagnostics” on page 6-26.
Verifying power supply operation
The power supply is divided into two sections: the AC section used for heaters
and the DC section for control logic, printhead drivers and motors. Verifying
the power supply involves five steps:
■
Checking for proper AC voltage.
■
Testing DC output voltages.
■
Inspecting the power supply fuses.
■
Testing for a shorted DC output supply which shut down the power
supply.
■
Testing for a shorted motor which shuts down the power supply.
Inspecting the power supply fuses
The power supply features one 10 A, 250 VAC rated fuse.
1.
Turn off the printer and unplug the power cord from the printer.
2.
Measure the fuse with an ohmmeter to verify it is functioning.
Measuring power supply voltages
1.
Turn off the printer and unplug it from its power outlet.
2.
AC Input:
With the VOM set to measure AC voltages, measure the
power being supplied to the printer. It should measure between 85 to
132 VAC (110 VAC nominal) or 180 to 264 VAC (220 VAC nominal).
