2. If CR16 is not on, but 24V is present at P/J27 pin 1, go to the 01G Fused Distribution
Check. If +24V is not present at PJ 27, pin 1, check the voltage at P/J26 pin 9. This is the
Low Power Mode Enable signal. If this signal is high, install a new LVPS and base mod-
ule, PL 1.10 Item 3.
3. If no LEDs are on, or only the CR36 3.3Vsb is on, go to 01H Short Circuits and Overloads
RAP.
IOT PWB Communications Check
1. Switch off the machine GP 14. Switch on the machine, GP 14. Observe the following con-
ditions, Figure 1:
• CR14 is off.
• CR27 is flashing at about 2 Hz.
• CR28 and CR29 are flashing alternately at about 1 Hz.
2. If any of the above conditions do not apply, perform the steps that follow:
• Switch off the machine, GP 14.
• Use the jumpers to short J 17 pins 1 & 2, J 18 pins 1 & 2, J 19 pins 1 & 2, Figure 1.
• Switch on the machine, GP 14.
• After the machine has power up, switch off the machine, GP 14.
• Lift the jumpers from J 17, J 18 and J 19. Park the jumpers on one pin only.
• Switch on the machine, GP 14.
3. If any of the above conditions still fail, then install a new IOT PWB, PL 1.10 Item 2.

OF8 Multi-feed RAP
To solve several sheet multi-feeds or extra blank sheet output problems.
Initial Actions
• Check the condition of the paper. Do not use incorrectly cut paper, damp paper, paper
with rough edges, badly drilled paper, paper with wrapper wax or glue contamination.
Refer to IQ1 Image Quality Entry RAP.
• Check the paper specification, GP 20.
• Multi-feed from the bypass tray, go to 07C By-pass Tray RAP
Procedure
When checking for multi-feeds always use a new ream of paper. If a new ream can not be
used, then perform the following:
• Fan the paper.
• Turn the paper round or turn the paper over.
• Remove four or five sheets from the top of the stack.
• When loading multi-reams of paper into the tray 3 or tray 4. Remove the top and bottom
sheet from each ream. This will prevent ream interface multi-feeds.
For tray 1 and tray 2 check the following:
• Check that the paper tray side guides are set to the correct paper size.
• The paper tray drops down when the tray is pulled out and the tray elevates up when
pushed in.
– Check the paper feed assembly, REP 8.1.
– Check the paper feed rolls, REP 8.35.
– Install new components as necessary, PL 8.26.
• The paper trays for worn, broken or missing components.
– Install new components as necessary, PL 7.10 Item 1.
For tray 3 and tray 4 check the following:
• The tray moves down when the tray is pulled out, and moves up when the tray is closed.
– Check tray 3 paper feed assembly, REP 8.2.
– Check tray 4 paper feed assembly, REP 8.3.
– Install new components as necessary, PL 8.30 Item 1.
• The paper trays for worn, broken or missing components.
– The separation strip is located correctly on the tray, Figure 1.
– Tray 3 only - Remove the spacers in the tray 3 feed assembly, Figure 2.
NOTE: The tray 3 spacers are fitted to reliably feed the sheets with large amounts of
up-curl, which normally occurs in very dry environments. Removing these spacers
decrease the multi-feed rate, but may increase the mis-feed rate if the paper is
curled.
These spacers are not fitted to any other tray.
– Install new components as necessary, PL 7.15.
