1. EA20 Paper Transport Stop Jam
There are a couple of areas that should be looked at when EA20 jamming is occurring.
Check for proper operation of Escape Solenoid (SL6) (part number 4402962760
SOLENOID).
If the Escape Solenoid does not operate properly then an EA20 jam could occur (see
Figure 1). The items to check for include:
o Binding of linkage
o Sticking of plunger
o Defective solenoid
Check the proper return operation of the buffer sensor (PI14).
We have had reports that either the first (M1) or second (M8) feed motors (part
number 6LE67833000 MOTR.S-FEED) could fail. The reports from the field are that
both motors need to be replaced at the same time. The reports state that replacing
one motor does not solve the problem and that both need to be replaced at the same
time.
2. CB30 Tray Lift Abnormality
There are a couple of causes of CB30, one is intermittent and the other is constant.
Intermittent
It has been noted in the field that an intermittent CB30 bin lift motor error may occur;
it usually occurs when the lower bin is driving. The cause is linked to the tie wraps on
the harness being too tight (see Figure 2). Over time, with the bins moving up and
down, damage occurs to the harness resulting in this error. As deemed necessary,
remove the cable ties. However, if the wires have already been damaged you may
need to replace the harness. (upper part number: 4G30851000; lower part number:
4G30852000 CABLE-TRAY)
