face of the drum.
3. With a new lint-free cloth (600S4372), wipe the entire surface of the drum, using moder-
ately heavy pressure. Use a back and forth motion of 6 - 10 strokes while revolving the
drum three revolutions.

GP 5 Communication Loopback Test
NOTE: in order to perform this test, it is necessary to use the Loopback Kit (600K43210).
1. Remove the Controller and disconnect the ribbon cable (J307B) from the IOT Main PWB.
2. Connect the 152K59420 loopback cable to J307B on the IOT Main PWB.
3. Connect the loopback tool 114E4680 to the loopback cable.
4. Enter [1402} to run the communication test.
5. If the test passes, a 0 will be displayed. The problem is then in the ribbon cable or the
Controller. Go to the E7-01 RAP in the AccXES Controller Service Manual.
6. If the test fails (1), replace the IOT Main PWB (REP 3.1).
