Miscellaneous Problems
Printer is Inoperative
The following characteristics define this type of problem:
■ The printer appears to have no power.
■ The control panel does not light up or display characters.
■ The printer motors do not run and the printer does not warm up.
■ The control panel does not display an error code.
The following procedure guides you through multiple actions that may solve this problem. Pro-
ceed one step at a time until the problem is solved. You may not need to complete the entire pro-
cedure. If one of the steps in this procedure corrects the problem but the identical problem
returns in less than 50 prints, call for service.
1. Make sure that you push the [ I ]on the main power switch to turn on the printer.
2. Check to make sure the AC power cord is firmly plugged into the AC wall outlet and that
the other end of the AC power cord is firmly plugged into the printer.
Sometimes the AC power cord is only partially plugged in and is not making good electri-
cal contact. If the AC power cord keeps working loose you might consider moving the
printer to a safer location. If the AC wall outlet is broken, allowing the power cord to eas-
ily fall out, replace the outlet.
3. Test for voltage present by plugging an AC electrical device, such as a lamp, into the AC
wall outlet. If the lamp does not light, inspect the building circuit breakers or check for a
broken AC wall outlet.
A circuit breaker trips because there was an overload on the line. A tripped breaker may
indicate that you have too many AC devices working off the same line or that you have
faulty building wiring. If the breaker is not tripped, but the lamp doesn’t light when
plugged into the outlet, replace the outlet or have an electrician check the line.
4. Turn the printer off and wait 20 minutes, then turn the printer on.
Thermal sensors may have shut down the printer. Waiting 20 minutes for the printer to
reset may return the printer to normal operation. A thermal shutdown may indicate there
is a more serious problem with the printer. If the problem reoccurs, call for service.
5. Call your service technician.
This problem may be caused by a malfunctioning or broken component that requires ser-
vice.
