Hardware Errors; Connection Errors - Ricoh A193 Service Manual

5.2 HARDWARE ERRORS

If the machine indicates an error message in the printer mode, check and
correct the following.
1. Does the machine work in copy mode?
2. Is the controller (or the related options) installed correctly?
If the problem still occurs, replace the unit that corresponds to the error.

5.3 CONNECTION ERRORS

If you have a problem regarding the controller connection with the machine or
the host (hardware or software), you may have the following symptoms.
1. The online LED does not light.
2. The machine does not go into the printer mode if the printer key is
pressed.
3. The data LED on the front panel does not light or blink.
4. The machine does not print, though the data LED lights or blinks.
Check and correct the following first.
1. Is the controller (or the related options) installed correctly?
2. Is the printer controller online?
3. Is the printer cable correctly connected?
4. Is the proper printer cable used?
5. Are the printer interface and the host's printer port set up correctly? (e.g.
flow control, transfer speed, stop bit, etc.)
6. Does the emulation mode of the printer match the selected driver?
If the connection problem still occurs after correcting the above problems,
replace the controller (if the parallel or the RS-232C interface is used) or the
printer enhancement unit (if the LocalTalk interface is used).
