Hi

 

Hope my solution below can help you resolve your problem.

 

 

Problem Description:

 

Touch Control Panel communication to the product functions at the initialization, but during
normal working the communication is lost.
Corrective action:


1. Reseat printer’s formatter (do this by loosening the formatter screws, disconnect and
reconnect the formatter, and tighten the screws again).
2. Replace the Formatter Board 


NOTE: For Revision B printers the Formatter and Hard Disk are replaced as a single
part,
3. Perform an Emergency FW Upgrade using a USB flash drive, 


4. Check connections of USB cable from Engine PCA to Interconnect PCAs.
5. Replace the HDD
NOTE: For Revision B printers the Formatter and Hard Disk are replaced as a single
part,
6. Replace the Interconnect PCA
7. Replace the Touch Control Panel
8. Check the event log at the EWS support pages to see if there is another SE (for instance
07:10) and troubleshoot the problem more accurately
