7.1 Outline of Troubleshooting
7.1.1 Outline
There are two types of trouble: trouble which is reported by the messages shown on
the display (“Warning,” “Error” and “Service call error”); and trouble not shown on the
display.
In this manual, a colon (:) is used to distinguish the first and second lines of the
message.
The alphanumeric code indicating the type of error, that is the "warning", or "error,"
will be displayed on the printer's display. The letters at the end of the code indicates
the following: W for the "warning" and E for the "error".
See
Part 3:
4.2 Error Indications
for a list of the problems which can be detailed on the
message display.
7.1.2 Notice for Troubleshooting
1. Obtain information about the system environment and the type of media used for
printing.
2. Before performing troubleshooting, make sure that all cables are connected
properly.
3. When servicing the printer with the external cover is removed and the AC power
connected, pay special attention when handling the electrical parts or the boards to
avoid an electric shock or short circuit.
4. In the following sections, the troubleshooting steps (action) are described such that
the component related to the most probable cause of the problem will be repaired
or replaced first, following by components with less failure probability. If multiple
components are the same probability of predicted failure, the steps are indicated
based on how easy the servicing is.
After performing a step, check to see if the problem has been solved by executing a
test print. If not resolved, proceed with the next step.
5. When the service has been completed, check to ensure that all connectors/cables
are reinstalled and screws are firmly tightened.
6. After performing replacement or repair services, run test prints to check whether
the problem has been solved.
