Q. Writing off the ARPB2 printer board if the flash upgrade instructions are
not followed.
A. When upgrading the flash memory of an ARPB2/ARPB2+ to an ARPB2a ensure that the new
flash upgrade procedure is followed. If the instructions are not correctly followed, it is possible to
write off the printer board. Please download the latest flash procedure from the Copier/AR
Product/ARPB2a area of the Sharp technical web.
Q. Fixing "F9-00" error codes.
A. An “F9-00” error is described as a “communication error between the ARPB2 and the ICU” board
of the copier.  However, there are additional conditions that might cause this error message.  These
conditions are as follows:
•  When printing a large complex graphic such as an Autocad drawing.
•  After fitting a Flash ROM chip to an ARPB2 that has previously been used as an Engine
Flash ROM chip.
•  When updating the ARPB2 firmware from 1.45 directly to 3.22
•  If the PB2 Flash ROM is faulty.
• 
If additional Installed RAM is faulty.
• 
If the Copier Engine Firmware is not at the latest level.
Refer to NIS Support Bulletin 027 for detailed information on each of the above points.
