During Enlarge, when the file was enlarged only by the specified size, the end code (FF02)
cannot be found in the compressed data.
Procedure
The problem occurs only for specific documents.
Y N
Perform following as required:
1. Ensure that the customer is programming a job within the parameters of the machine
utilizing the UI.
2. Check that connectors on the MCU PWB
are securely connected.
3. Check the sw version of the controller sw - update if required
4. Uninstall and reinstall the Page Memory and System Memory
5. If the problem persists, replace the Page Memory and System Memory
6. Replace RAM DIMM on ESS PWB
7. If the problem persists, replace the HDD
8. Perform GP 14 - only the first two parts - make sure to follow sequence and heed
cautions
a. Job Log Clear Mode
b. HDD Initialize Mode
9. If the problem persists, replace the ESS PWB
10. Replace MCU PWB (PL 18.2)
Perform following as required:
1. Reload Software (GP 16).
2. Change the Print mode (Normal/High Quality/High Resolution).
3. Change the port settings or the Receive Buffer size.)

024-371 IOT-ESS Communication Fail 21 RAP

BSD-ON: BSD 3.1 - ESS - MCU Communication
BSD-ON: BSD 16.1 - ESS
Sub System Fail. The communication between the ESS and IOT has not been established,
which is detected by the Controller. When the Controller and IOT are turned ON (including
recovery from Power Saver mode), a response from the IOT to a request to establish commu-
nications from the Controller was not detected within the specified time.
Procedure
• Turn the power OFF then ON.
• Ensure that the customer is programming a job within the parameters of the machine uti-
lizing the UI.
35.2) • Disconnect then reconnect the IIT, Control Panel, ESS, MCU all PWBs connected to them
(RAM, Firmware module, EEPROM)
• Check the sw version of the controller sw - update if required
• Replace MCU PWB (PL 18.2)
• Replace ESS PWB (PL 35.2) (If not fixed by this, reinstall the original ESS & MCU)
