Troubleshooting
OK?
Execute DRAM check 1. (Refer to Section 3-5.)
Print internal stair-step pattern. (Refer to Section 3-1.)
OK?
Execute DRAM check 2. (Refer to Section 3-5.)
Head control block on PRT-11 board is defective.
Check IC206, IC207, IC208, and IC210.
Check thermal head.
OK?
Interface circuit is defective.
Remote control circuit is defective.
Color adjustment and masking table blocks are defective.
Check IC209 on IF-787 and IF-788 boards and peripheral circuit.
Check IC102, IC107, IC108, IC110, and IC111.
Check IC101, IC105, IC106, and IC109.

6-1. Electrical System Problems
1. The system does not start.
<Cause>
Incomplete IC204 soldering, EPROM IC210 disconnection or defect can be
suspected.
2. All alarm LEDs light and stop when the power is turned ON.
<Cause>
System controller IC204 is not initialized normally.
<Countermeasure> Communication with the mechanical controller PRT-11 board may have failed.
Check the harness connecting CN204 on the IF-787 or IF-788 board and
CN006 on the PRT-11 board. Or communication with the EEPROM (IC201 on
the IF-787 or IF-788 board) may have failed. In this case, check the periphery
of IC201.
3. Data from the personal computer is not accepted (not operating with the driver software).
<Cause>
There may be problems in the periphery of the interface controller IC209.
<Countermeasure> Press S207 on the IF-787 or IF-788 board to perform the test printing.
If printing is not performed, defect of the periphery of the system controller
IC204 can be suspected.
If printed normally, check IC209 and IC102.
4. Printing result is no good.
