Advice 
Cougar 2k 
& AR505 
Machine slows down in duplex mode 
when fitted with an external coin vend. 
This is specification. The machine will 
complete each duplex copy before 
starting the next to ensure there is 
enough credit available. To overcome 
this, use the coin vend output signals 
from the operation PWB instead of the 
PCU. 
Cougar 2k 
In either copy or print mode, the 
machine will print the first page and 
wait for a period of time before the 
next page is printed. 
Faulty HDD. Use Sim 61 and execute 
a full read/write test (will take approx 
10 mins). If NG appears, replace the 
HDD. 
AR405 
Main motor continues to operate when 
using cover page insertion at 129% 
and 2 position stapling (FN1). 
Upgrade engine firmware to the latest 
version. Must be v2.02 or higher (All). 
AR280/285/
335 
No pamphlet mode. 
Sim 26-01 not set for duplex. 
AR280/285/

No display after changing the ICU 
Pwb. (Fans running) 
Remove IC22 and retest. If display 
works ok, replace IC22. Also check 
CN1 on ICU Pwb for poor connection. 
 
On AR280/285/335 models, a mixture 
of v2 & v3 flash cards will cause the 
same symptom.
